Repair of the pendulum arm (pendulum) for VAZ 2101-VAZ 2107

The pendulum lever (also known as the “ pendulum”) on the VAZ 2107 is designed for one simple function - synchronous rotation of the front wheels through the steering mechanism. It is thanks to him that the left and right wheels turn in the direction desired by the driver simultaneously, without delay, when turning the steering wheel. This ensures vehicle stability when cornering.

A malfunction of the VAZ 2107 pendulum worsens the vehicle’s performance when maneuvering and can lead to an accident. Therefore, at the first sign of its malfunction, it is necessary to repair or replace the unit.

Replacement of the pendulum lever of VAZ 2107, VAZ 2104.

Pendulum design for VAZ 2104 - VAZ 2107
1 - bipod; 2 — bracket body; 3 — washer; 4 — adjusting nut; 5 - cotter pin; 6 — upper washer; 7 - seal; 8 — bushing; 9 – axis; 10 - lower washer; 11 - lock nut.

Many owners of VAZ 2104 - VAZ2107 cars buy, make repairs and change the pendulum themselves.

To do this you need:

This must be done carefully so as not to strip the threads or flatten the castle nut, so it is better to screw on another nut.

remove by unscrewing two nuts, while on the other side you need to put on an adjustable wrench that will keep the bolt from turning;
unscrew the top nut;
remove the axle from the bracket. During assembly, add lubricant to the pendulum arm bracket.
The bushings should fit tightly in the bracket, and the axle should have no radial play. When the bushings are worn out, replace them with new ones.
check the turning torque of the axle - by tightening or loosening the nut, observe while turning the bipod. When turning, the bipod should “walk” easily and without effort. The lighter this force, the less it will be transmitted to the steering wheel.

Designs on bearings cope better with this task.

check the play on both sides;
tighten the top nut;
install the bracket in place.

Repairing the pendulum on a VAZ 2104 - VAZ2107 car is not difficult and will not take much time, but to be sure of the result, it is better to contact a professional.

Can it be tightened or do I need to install a new one?

If it rattles, you can tighten it if the car is not old, I tried mine - I unscrewed the nut with my fingers. 1. I bought a repair kit and a tube of Litol-24. 2. Removed the cotter pin and unscrewed the nut. 3. Lowered the shaft down. 4.I removed the housing by unscrewing it from the mudguard. 5. I cleaned everything, replaced the bushings and anthers (the old ones were in good condition). 6.Nabil Litol-24. 7. I screwed the housing to the splash guard. 8.Inserted the shaft, tightened the nut, and inserted the cotter pin. Everything was done without a pit, with the right wheel removed, for 50 minutes. Costs - 30 rubles. repair kit, 20 rubles, tube of Litol-24.

Can it be tightened or do I need to install a new one?

Is the pendulum lithium 24? As far as I remember, there is white grease there.

Basic engine malfunctions

VAZ 2107 cars are equipped with three main types of power units with a displacement of 1.5, 1.6 and 1.7 liters. The second engine is equipped with a distributed injection system, which differs significantly from carburetor engines. During long-term operation, parts and components of the unit are subject to wear, which can cause the following malfunctions:

Failure of the power supply system: fuel pump, low or high pressure pipelines.
Clogging of the main fuel or air jet, damage to the starter membranes or other mechanisms.
Failure of the ignition system: high-voltage wires, spark plugs, distributor or other mechanisms.
Oil pump failure, filter clogged.
Extreme wear of parts of the cylinder-piston group, crankshaft or camshaft liners, timing belt.

Diagnosis of injector or ECU malfunctions is carried out using a special tester, which is available at specialized service stations. Repair and restoration work on the engine is classified as complex and requires high qualifications and special skills.

Disassembly and assembly of the pendulum lever VAZ 2106-2103

As a rule, the pendulum arm is disassembled if the resulting play cannot be eliminated by simply tightening the nut. In this situation, the entire bushing will need to be replaced. For repairs, prepare pliers, a screwdriver, a 19mm wrench and a torque wrench.

Disassembling the pendulum mechanism

Clamp the lever together with the bracket in a vice and, unscrewing the nut, unscrew it. Remove the nut and the top washer on the lever axle together with the washer by prying it off with a screwdriver.

Next, release the bushing with the seal from the lever axis and remove the bracket. Do the same for the next bushing with its seal.

Disassembly of the lever is now complete. You will need to conduct a thorough inspection of all removed parts. For example, the axle should not show any noticeable defects caused by wear of the part or corrosion deformation. There should be no signs of wear on the bushings. If any of the above defects occur, then these parts should be replaced with new ones.

Assembly of the pendulum mechanism

Assembly must be done in the reverse order of disassembly. Don't forget to lubricate the hole in the bracket for the axle, as well as the axle itself. After the pendulum arm is completely assembled, the nut should be tightened with a torque wrench with a certain pressure force (1.5-2 kgf). After this, be sure to tighten the nut.

Assembly of the unit

After removing the old rods, take a tape measure and measure their length. The problem is that you will have to adjust the wheel alignment - you won’t be able to do this yourself, it’s better to go to a service station and do diagnostics on a computer stand. After replacing the steering tips of a VAZ-2107, even if you have achieved the same length with the new elements, it is necessary to carry out diagnostics. Otherwise, when driving, tire wear will occur much faster.

Installation of new tips is carried out in the reverse order. Insert the ball pins into the steering knuckles and holes in the bipod, tighten the nuts and secure their position with cotter pins. It is advisable to purchase new cotter pins, as old ones are usually covered with a layer of dirt and rust.

Today, the next article in the series “Crystal VAZs or typical breakdowns of domestic cars” is dedicated to the “classics”: VAZ-2101, 2103, 2104, 2104, 2105, 2106 and 2107. These cars have been driving along our roads for decades and, despite Despite all the shortcomings that we will talk about, their popularity is still high.

How to identify a faulty pendulum

The easiest way to determine if the lever is faulty is to listen for knocking noises while driving on rough roads. You shouldn’t deliberately drive into a hole or run over a bump, so you can pull over to the side of the road and experiment

But this is not the only way to determine the malfunction of such an important part as the pendulum

The second way to determine whether the VAZ 2107 pendulum arm is faulty is the presence of large play in the steering wheel. This can be determined quite simply by turning the steering wheel in one direction and the other. But the most common case of pendulum failure is the presence of load when turning the steering wheel. But these factors do not always indicate that the pendulum lever is the culprit. Malfunctions with such symptoms may include loosening of the bolts or overtightening of the adjusting nut. Therefore, before you start replacing the device, you should definitely make sure that it is broken. This can be done after dismantling it. The first sign of a part malfunction is the presence of defects on its component elements, so to determine the failure you will need to disassemble the mechanism.

Body, front and rear suspension

The VAZ 2107 model belongs to the so-called classic series. During operation, paintwork is exposed to moisture and damage from stones. Exposed metal causes corrosion processes that not only spoil the appearance of the car, but also significantly weaken it. This is especially true for elements of the supporting frame: side members, sills and body pillars.

The main malfunctions of the front suspension: destruction of ball joints, silent blocks, failure of shock absorbers. Failures of this kind are accompanied by a knocking sound at the bottom of the car while driving. In the rear suspension of the VAZ 2107, rubber-metal bushings mainly fail. This causes the car to move away from a given trajectory, especially when making turns and on uneven roads.

Replacing the swing arm

If repair is not possible, you can install a new swingarm and secure it. The procedure is the reverse of removing the pendulum from the car body.

Replacing the pendulum on a VAZ 2107 is a fairly simple process. You can make it yourself.

The first signal that needs to be taken into account and the pendulum replaced is a bent bipod of the pendulum arm. It is possible to carry out repairs to replace the pendulum without an overpass. Initially, it is necessary to dismantle the main filter housing so that it does not interfere. Next, you need to unscrew the castle nuts of the tie rods, as well as the ball pin nut. After this, it is necessary to press out the ball pins of both steering rods. To do this, a long steel rod is used, which is struck with a hammer.

Trouble-shooting

As the vehicle is used, individual components of the steering mechanism gradually wear out. For comfortable and safe driving, as well as to prevent uneven tire wear, any defects in the steering mechanism must be corrected in a timely manner.

Steering gearbox

To identify problems with the steering column, the unit will need to be removed from the car. To do this, you need to prepare the following list of tools:

a set of keys;
knob;
heads;
steering rod puller.

Dismantling is carried out in the following sequence:

We drive the car onto an overpass or lift.
We unscrew the fastening of the cardan to the column shaft.
We unscrew the nuts that secure the tie rod pins to the bipod, and then use a puller to squeeze out the pins.

Let's disassemble the mechanism for troubleshooting parts:

Using a 30mm wrench, unscrew the nut holding the bipod.

Inspect the roller and worm for wear or damage. The gap between the bushings and the bipod axle should be no more than 0.1 mm. The rotation of the bearings should be easy and without jamming. Any defects on the internal parts of the bearing are considered unacceptable, as are cracks on the mechanism body. Damaged parts are replaced with serviceable ones. Before assembling the mechanism, lubricate all elements of the gearbox with transmission oil and perform the assembly:

We hammer the bearing ring into its seat.

Repair of the pendulum arm (Pendulum) on VAZ 2101-VAZ 2107

Welcome! Pendulum lever - over time, like any other part, the pendulum lever, or as it is also called simply “Pendulum”, becomes unusable, and the cost of this lever for some will seem too small, and there will be those people for whom the cost of the pendulum lever will seem too big.

Therefore, in order not to spend money and buy it new right away, you can first try to repair it at minimal cost, but with the loss of some time, which, compared to money, will seem like a more acceptable option.

Note! To repair the pendulum, you will need: A set of basic wrenches, a vice, as well as a screwdriver, pliers, and it is also recommended to stock up on a dynamometer thanks to which you can determine with greater accuracy under what action the bipod of the lever rotates (More details will be discussed in the article, a little below)!

Where is the swing arm located? It is located at the very bottom of the car, and this is easy to understand, because as such the pendulum is part of the main part of the car’s chassis. (But still, you can see a more detailed location of the pendulum in the article entitled: “Replacing the pendulum arm on a VAZ”)

Why do you need to repair the pendulum arm? In most cases, the pendulum is disassembled, thereby repairing it in order to replace the main bushings in it, due to which play appears in the pendulum, which in turn cannot be removed by tightening the pendulum nuts.

Installing a lift kit on Niva 2121

Hello, dear friends! Today I propose to talk to you about the elevator kit for the Niva. This could be a Chevrolet Niva, that is, series 2123, or the more “our” Niva Urban, 2131 or 4x4, and representatives of the 2121 series, that is, 21213, 21214. It all depends on what kind of car you have at your disposal.

Russia, Ukraine, Belarus and a number of other countries are the greatest admirers of Niva cars. They are affordable and provide many benefits.

Some people prefer to do everything themselves. I can’t say that modifying the front and rear suspension of a Niv car will be an easy job in a minute. No, you will have to spend a lot of effort, time and patience on this.

Increasing the ground clearance of the VAZ 2121 (lifting) allows you to increase the vehicle's off-road capability. Thanks to simple manipulations, the ground clearance increases significantly by changing the suspension height (the Niva lift kit will help you here, which makes the work very easy to do even with your own hands without the help of a service center) and installing slightly larger diameter wheels.

Also interesting: Tuning Niva 2121 with your own hands: body, interior, suspension

Lifting - increasing the vehicle's ground clearance by upgrading the suspension. Performed in order to increase cross-country ability.

We propose to consider this issue in more detail.

As a rule, a lift kit for Niva 2121 includes:

Rear and front springs.
A set of spacers for the upper ball joint.
Front oil shock absorber.
Adjustable Panhard rod.

Steering problems

The steering mechanism, like any other vehicle component, wears out and requires repair over time. To simplify the troubleshooting, there are certain signs that allow you to find out the nature of the breakdown and fix it in a short time.

Oil leak

On a classic, the problem of a “wet” steering gear is quite common. There can be many reasons for this:

oil seal wear;
leakage from under the gasket;
loosening of the fasteners that secure the mechanism cover;
Corrosion of the input shaft.

If the oil seal and gaskets can be replaced and the bolts tightened, then if the shaft is damaged, the part will have to be ground.

Tight steering wheel

Sometimes it happens that to turn the steering wheel it is necessary to apply noticeably more effort than usual. Several reasons can lead to this malfunction:

incorrect wheel alignment;
failure of one of the elements in the steering mechanism;
the gap between the worm and the roller is broken;
The pendulum axis fasteners are too tight.

Steering play

One of the reasons for free play in the steering mechanism is wear on the shaft crosspieces. In addition to them, play appears in the gearbox itself. If the unit has a high mileage, then it is advisable to disassemble it, inspect the condition of all the elements, replace parts with high wear, and then carry out adjustments.

Knock and vibration

If you feel feedback on the steering wheel while driving, there can be many reasons for this phenomenon. Driving a vehicle in such a technical condition leads to rapid fatigue and reduces the level of safety. Therefore, the steering mechanism needs diagnostics.

Table: causes of vibrations and knocking on the steering wheel and ways to eliminate them

Cause of steering failure	Troubleshooting method
Increased clearance in front wheel hub bearings	Adjust the front wheel hub clearance
Loosening the tie rod ball pin nuts	Tighten the tie rod ball stud nuts
Increased clearance between the pendulum arm axis and the bushings	Replace the swingarm bushings or bracket assembly
The adjusting nut of the pendulum arm axis is loose	Adjust the tightness of the swingarm nut
The clearance in the engagement of the roller with the worm or in the worm bearings is broken	Adjust the gap
Increased clearance in steering rod ball joints	Replace tie rod ends or tie rods
Loosening the bolts securing the steering gear housing or the pendulum arm bracket	Tighten the bolt nuts
Loosening the swing arm nuts	Tighten the nuts

On needle bearings it would probably last forever

good, I also ordered a Miasovsky pendulum for my Nivasik

Listen, tell me, will it be easier to turn the steering wheel or not with a bearing? I want to install it for myself, if it makes sense and which one is better to take?

depending on the condition of your bushing pendulum and gearbox. Of course it spins easier compared to stock; a friend’s car just felt like the steering wheel was spinning with a smaller diameter. There was a Gusev pendulum - I broke off his ear, then I put the car in a green box and it still drives.

Gusevsky bullshit + just reinforced. I installed it, first of all it tightens my pants and when I turn to the right there is a hum, and secondly it gets loose and there is a knocking sound. I want to change it to a bushing or normal bearing. How to drive an AutoReal vehicle?

The man is still skating. With taxiing - it floats a little at speed, for him. After the Corolla, I felt the same way too.

Steering VAZ 2107

The steering mechanism of the VAZ “Seven” consists of several units connected together by means of fasteners. These components and their constituent elements, like any other part of the car, wear out over time and become unusable. The purpose, design, repair and maintenance of the VAZ 2107 steering system should be discussed in more detail.

Purpose

The main function assigned to the steering mechanism is to ensure the vehicle moves in the direction specified by the driver. On most passenger cars, the trajectory of movement is carried out by turning the wheels of the front axle. The steering mechanism of the “seven” is quite complex, but at the same time it provides trouble-free control in different situations on the road. The car is equipped with a safety steering column with a driveshaft that folds upon impact. The steering wheel of the mechanism in question has a diameter of 40 cm and to completely turn the wheels you need to make only 3.5 turns, which allows you to perform maneuvers without much difficulty.

What does it consist of?

The front wheel control mechanism on the VAZ 2107 is made of the following basic elements:

steering wheel;
shaft;
gearbox;
bipod;
trapezoid;
pendulum;
steering knuckles.

Steering shaft

Through the shaft, rotation from the steering wheel is transmitted to the steering column. The shaft is secured with a bracket to the car body. Structurally, the element is made in the form of a cardan with crosspieces and an upper shaft. In the event of a collision, the mechanism folds, thereby ensuring the safety of the driver.

Gearbox

The VAZ 2107 is equipped with a worm steering column, which converts the rotational movement of the steering wheel into the translational movement of the steering rods. The operating principle of the steering mechanism is as follows:

The driver turns the steering wheel.
By means of cardan joints, the worm shaft is driven, thereby reducing the number of revolutions of the steering wheel.
The worm element rotates, moving the double-ridge roller.
The secondary shaft rotates, on which the bipod is fixed, driving the steering rods.
The trapezoid moves the steering knuckles, turning the wheels in the desired direction.

Steering linkage

The radius of the vehicle's trajectory when turning depends on the angle of rotation of the wheels. Since the outer wheel has a larger radius than the inner one, in order to avoid the latter slipping and deteriorating traction with the road surface, the front wheels must deviate at different angles.

This is what the steering linkage is used for. During the maneuver, the transverse thrust of the mechanism shifts under the influence of the bipod. Thanks to the pendulum arm, it pushes and pulls the side rods. Since misalignment occurs, the impact on the tie rod ends is different, which leads to the wheels turning at different angles. The tips of the trapezoid with the rods are connected through adjusting couplings, which allow you to change the angles of rotation of the wheels. The parts of the trapezoid are connected to each other by identical ball joints. This design contributes to the normal operation of the unit even when driving on bad roads.

Pendulum arm

The steering pendulum of the “seven” is necessary for synchronous rotation of the wheels of the front axle without lag. Thus, the car is able to corner safely. If malfunctions occur with the pendulum, the vehicle’s performance during maneuvers deteriorates, which can lead to an emergency.

Steering and braking system

The VAZ 2107 model car has good handling. The worm-type steering mechanism is quite reliable; wear appears mainly in the ball ends of the rods. Delaying repairs can lead to their breakage and loss of control of the car while driving. Wear of the pendulum bushings is accompanied by knocking and an increase in backlash to unacceptable values.

The VAZ 2107 has a dual-circuit hydraulic brake system with a vacuum brake booster. The most common breakdowns:

Wear of brake pads, drums and discs beyond the maximum level.
Leakage of brake fluid as a result of wear of the sealing rings and the appearance of cavities in the master brake cylinder.
The appearance of fistulas in brake hoses.
Jamming of pistons in the cylinders of the actuator.

It should be remembered that traffic rules prohibit driving a car with faulty steering mechanisms or operating circuits of the brake system. If damage of this kind is detected, you should call a tow truck to deliver the car to the parking lot and repair.

Types of pendulums for VAZ 2104–2107

In the manufacture of pendulum levers, bushings are used, and the bearings on which the lever axis rests. They are designed to provide longer service life for moving parts. Manufacturers believe that bushings are more durable because, unlike fragile bearings, they are not subject to influences other than abrasion. However, both materials are subject to wear. If the elements are worn out, the driver will feel more tension in the steering wheel than usual, and it becomes difficult to control the car due to increased play. When hitting a hole or bump, extraneous knocks begin to be heard from the side of the pendulum, and the steering wheel travel increases. And if the mechanism itself is damaged, the bolts are loosened, or the adjusting nut is overtightened, then the wheel will rotate more tightly.

The designers tried to make the pendulum airtight and isolated the internal cavity of the body with two rubber rings, but usually after traveling 45–90 thousand km it has to be completely changed. When a car drives onto country roads, all the dirt is pulled inside.

Functions and purpose

The steering gearbox is installed on the driver's side, and the steering pendulum mechanism is connected to the bipod on the passenger's side. They are connected to each other by a steering rod and serve as support points. The driver controls them by acting on the steering rod.

The pendulum body is made of cast iron or aluminum and has the shape of a cylinder with holes for attaching it to the spar or to the frame. In the center, an axle is inserted through a hole, which is threaded through the body and makes the handle more movable, and also serves as a support for the steering rod. The other end of the bipod moves like a pendulum and therefore has this name.

Replacing the pendulum arm (Pendulum) on a VAZ 2101-VAZ 2107

Welcome! Pendulum arm – popularly this unit is simply called “Pendulum”. You need this unit to turn both wheels at the right moment in time. Essentially, due to the “Pendulum Lever”, it creates synchronism when turning the wheels, that is, thanks to it, both wheels turn at the same moment and without delay, respectively.

Note! To replace the pendulum, be sure to stock up on: Two 17" wrenches!

Where is the swing arm located? It is located under the bottom of the car, you can see it by opening the hood of the car and looking at the very bottom of the engine compartment, and the easiest way to look at it is from the bottom of the car, to do this, climb under the car and find the lever there that comes from the pendulum itself, and for clarity, this lever is indicated by an arrow.

Note! In fact, it is incorrect to use the word lever in the pendulum (this was done only for convenience), in fact, no lever comes from the pendulum, but only a bipod, which is indicated by the arrow, comes from it!

When should the swing arm be replaced?

Basically, after the pendulum arm fails, knocking noises begin to be heard from the lower part where it is located, which will be especially audible when hitting a bump.
In addition to knocking, the free play of the steering wheel, popularly called play, can also be increased.
Also, the steering wheel itself may be difficult to turn due to the failure of the pendulum arm.

Note! All these signs relate to a malfunction of the pendulum, but they can also occur when the pendulum bolts are loose or the adjusting nut is too tight, so before replacing the pendulum arm with a new one, check the tightness of the bolts and either loosen or tighten them as necessary!

How to replace the pendulum arm, also known as the pendulum, on a VAZ 2101-VAZ 2107?

Removal: 1) First, disconnect both tie rod ball joints that are connected to it from the pendulum. (How to disconnect the hinges, see the article: “Replacing steering rods on a VAZ”)

2) Then take two wrenches in your hands and with one of them at this time hook onto the bolt that secures the pendulum, so that the bolt does not turn when the nut is unscrewed. After you grab the bolt, use a second wrench to unscrew the nut of the bolt you are holding.

Note! There should be washers under both nuts, so if you have them, then remove them, and if there is more than one on one bolt, then before removing the washers, remember which bolt had what number of washers and when reinstalling it, place the required number of washers under the nuts !

3) Now remove the two bolts that secure the pendulum and, as a result, remove the pendulum arm from the car.

Note! Before installing a new pendulum on a car, make sure that it has been assembled correctly; to do this, clamp the pendulum in a vice so that its bipod is directed strictly horizontally. In this position, under the weight of its own weight, the bipod will have to stand in one place, not moving anywhere. It will only have to move under the influence of a force of “1-2 kg” applied to the part on which the right tie rod joint will be installed, in other words, to the tip of the bipod as shown in the figure:

How to identify a faulty pendulum

But this is not the only way to determine the malfunction of such an important part as the pendulum

Location of the pendulum on the VAZ 2107

This product is located on a VAZ 2107 car from below the engine compartment. You can see the pendulum when you open the hood and look at the bottom of the car on the passenger side. It is most convenient to dismantle or examine the device from below from an inspection hole or on an overpass.

A bipod extends from the pendulum, which controls the rotation of the front wheels of the VAZ 2107. The photo below shows a view of the pendulum arm on the VAZ 2107.

Removal and repair of the pendulum

To carry out the work, you will need to stock up on a standard set of tools and a steering rod puller, and then begin the work process:

After removing the product, it is replaced or repaired. Installation of a new pendulum arm is carried out in the reverse order of removal. It is advisable to replace the pendulum arm only if it cannot be repaired. In frequent cases, the product can be repaired, which many motorists do on their own.

Repair of the mechanism is carried out using the following procedures:

The product is assembled in the reverse order of removal, but initially all parts should be lubricated with Litol-24

This completes the replacement of such an important device on the VAZ 2107. After assembly, you should check the steering wheel play

Currently, pendulum arms with rolling bearings are also sold on the market. There are different reviews about the reliability of this option. Everyone is inclined to believe that the pendulum on bearings facilitates the rotation of the steering wheel and lasts several times longer than the factory one, but it is not repairable. In the end, the choice is yours.

Electrical equipment main causes of malfunctions

The on-board network of the VAZ 2107 is powered from the battery, and after starting the engine from the generator. The most common causes of electrical equipment failures:

Failure of the voltage regulator, significant wear of the brush assembly and slip rings, and the generator drive belt.
Undercharging a battery for a long time causes sulfation and destruction of the plates, which leads to a decrease in its capacity.
A breakdown of the solenoid relay or damage to the stator or rotor winding makes it difficult to start the engine.

Any malfunctions of the VAZ 2107 car are diagnosed by employees of service stations or independently. The method of restoring the functionality of systems and mechanisms usually involves replacing failed parts. Experienced car enthusiasts can fix most breakdowns on their own using illustrated repair manuals.

Transmission - causes of failures

The VAZ 2107 is equipped with a four- or five-speed gearbox with mechanical shifting and a diaphragm single-plate clutch. The most common causes of transmission breakdowns:

Wear of the sealing elements of the hydraulic drive and the formation of wear in the cylinder.
Breakage of the release bearing, destruction of the diaphragm spring, drive or driven disk.
Leakage of transmission oil from the gearbox, breakdown of bearings, shafts, gears, synchronizers and other parts.
Breakdown of the gear shift unit.

The causes of a transmission malfunction are identified by indirect signs: the appearance of extraneous noise and vibration while the vehicle is moving. There may be difficulties when engaging certain gears, jerks and jolts. Repair of the clutch, drive, gearbox and other transmission mechanisms involves the need to dismantle these components, disassemble and check all parts for compliance with the parameters.
