MAZ clutch and part device
The MAZ clutch is a double-disc friction type device. It has springs that are located peripherally. The MAZ clutch device also includes discs. The elements are made of durable materials. The MAZ clutch is installed in a crankcase made of strong cast iron. The leading parts of the mechanism are the MAZ clutch disc (middle and pressure) and the MAZ flywheel. AvtoResurs LLC offers a closer look in a number of articles on how to adjust the MAZ clutch and repair the part. However, today we will tell you what the MAZ clutch device consists of and how the MAZ clutch drive works.
1. The MAZ clutch has a complex structure
Let's look at the Minsk Automobile Plant truck model 5335. Let's carefully study the MAZ clutch design. So, the mechanism includes a huge number of elements, for example:
- Release lever and springs;
- MAZ clutch fork, rings, rod;
- Nut, plates, MAZ clutches;
- Fork shaft lever, pin, MAZ clutch cover;
- Gaskets, MAZ clutch disc, flywheel and hubs.
These components are the main ones in the design of MAZ spare parts. Also, all mechanisms are strong and resistant to heavy loads. Therefore, the MAZ clutch, as well as the MAZ clutch drive, last a long time and rarely fail. Cast iron is mainly used for the manufacture of elements from the MAZ clutch device. Let's take a closer look at each part of the part being studied. The MAZ clutch disc (pressure and drive) is cast from durable cast iron.
Has spikes that attach to the truck's flywheel. Thus, the MAZ clutch is a very strong connection, which makes it easy to move the MAZ clutch disc. Also in this case, torque is transmitted to an element such as the MAZ clutch disc from the flywheel. A frictional force arises. The MAZ clutch has several friction attachments that contain the MAZ clutch disc. Therefore, during the operation of the elements, a frictional force occurs. That is, torque is transmitted from the surface of the friction linings, discs and flywheel to the MAZ gearbox. Note that the MAZ clutch drive of a modern truck does not include discs. 2. MAZ clutch is reliable and strong
We continue to consider the MAZ clutch device.
To prevent heating of the springs, which most often occurs when the truck slips for a long time, a pressed cardboard gasket is adjusted under the springs of the MAZ spare parts. The MAZ clutch disc is not interchangeable. The elements are mounted on the MAZ input shaft, that is, on its splines. The MAZ clutch also includes a hub, a disc with linings and a vibration damper.
As a rule, MAZ hubs and MAZ clutch discs are made of steel. The MAZ clutch is protected from the harmful effects of various vibrations when the vehicle is moving thanks to a special damper. These vibrations are most often transmitted from the truck engine shaft. In addition, the MAZ clutch device is reliably protected by a failure absorber when the mechanism is engaged. The damper also allows the gearbox gears to operate more smoothly.
The MAZ clutch disc is not included in the drive to disable the mechanism in question. So the MAZ clutch device when turned off is approximately the following:
- Pins, rods and pedals;
- MAZ clutch levers, springs and forks;
- Cylinder rod, cylinders and retaining ring;
- Gap and valve.
Thus, the MAZ clutch drive is equipped with a pneumatic booster. In general, the part is strong and practically does not break. However, the MAZ clutch drive, like any element of a truck, requires regular inspection. The rods and valves are connected in series. Thus, the mechanical clutch drive is also equipped with a working cylinder of the amplifier. The element is installed in parallel. The MAZ clutch drive includes in its MAZ clutch device and a double-arm lever, which is connected to the cylinder and valve rod. As you can see, the MAZ clutch diagram is simple. However, before adjusting the units, it is necessary to carefully study their design. If we consider the MAZ clutch drive, the element is adjusted in two ways.
That is, by adjusting the free play of the MAZ clutch pedal. In addition, the MAZ clutch drive is regulated by the gap between the ring (retaining ring) and the end of the valve body cover. The MAZ clutch disc does not require special care.
Inspect the part regularly to ensure timely repair of breakdowns. The MAZ clutch drive is also unpretentious.
Just periodically check the free play of the pedal and clutch bearing.
The MAZ clutch device also contains a drive. We recommend that you monitor the condition of this item more carefully. Subscribe to our channels on social networks twitter, facebook, contact, google+.
Design features
The clutch of this model is usually installed on heavy, powerful equipment.
YaMZ 238 is a dry double-disc friction-type clutch; the mechanism’s cylindrical springs are peripherally located.
The engine power and the actual design features of the mechanism very often lead to the fact that an incorrectly configured clutch can easily fail. In order to avoid breakdowns, it is necessary to diagnose and adjust the YaMZ 238 clutch at least once every six months.
Required Clutch Maintenance
Every time you start maintenance of the clutch, you must adhere to a strict sequence so as not to miss anything important and notice the problem in time:
- The first step is to check and, if necessary, adjust the free play of the clutch responsible for engaging the clutch (the gap should be 3.2–4 mm).
- Next, you need to check the mechanism for lack of guidance. (check is carried out with the engine running in first gear and with the clutch disengaged).
If you find out that the value is far from the maximum norm, there is only one way out, adjusting the YaMZ 238 transmission.
Pumping the node
To bleed the clutch, you need to fill the hydraulic reservoir with water, this should be done gradually to a level of 1-1.5 cm. It is necessary to clean the cylinder exhaust valve, it is dirty. It is necessary to remove the special cap from its head and install a rubber hose on the cylinder. Now the end of the hose must be inserted into the hydraulic fluid, which is poured halfway into a liter jar. To pump the clutch, you need to slowly press the pedal of the unit at intervals of 1-2 seconds. You need to press about 4-5 times. Without strict adherence to all points of the instructions, the result may be zero, so you must be careful when bleeding the clutch.
Service
Maintenance of this mechanism is carried out as follows:
- Carry out an external inspection of the pedal and, if necessary, adjust its free play.
- Bleed the hydraulic drive.
- Carry out diagnostics of the crankcase fastening elements and, if necessary, tighten the nuts.
- Carry out an external inspection of the tension spring device, lubricate the bearings and hydraulic coupling.
- Check the functionality of the clutch switch and the shaft sleeve.
- Inspect the fork and clutch pedal for wear and damage.
- Check the operation of the mechanism by changing the gears of the vehicle on the spot and during acceleration.
- Eliminate incorrectly set gaps between support rings and washers.
- Eliminate leaks in the system and lubricate all cylindrical elements with a special liquid.
- Check the gap between the rods and the piston part of the main cylindrical device.

Manufacturability of the production process, allowing to meet the most stringent European requirements for product quality. MAZ clutch baskets produced by TD SPETSMASH are guaranteed to comply with the ISO 9001 standard, which means that the quality of such products is at the highest level.
The advantage of a diaphragm clutch is the nonlinearity of the diaphragm spring characteristics. If the cylindrical springs of the lever clutch, as the driven disk wears out, reduce the pressure force causing slipping, then the diaphragm clutch, on the contrary, slightly increases it and therefore lasts longer (i.e., the maximum wear of the driven disk increases significantly).
There is no need to periodically adjust the clutch lever feet,
Focusing on the secondary market for automobile clutches makes our MAZ clutch cheaper than those from other major manufacturers. As a result, the attractiveness of such a clutch for the buyer increases significantly.
