How to adjust the clutch?

The operation of any car implies the carefor him. But, not knowing the instructions and doubting the correctness of their actions, you should not climb under the hood of the car. The article will tell you how to adjust the coupling of the MAZ truck.

Clutch device

In the car MAZ clutch dry, two-disc,The friction type is arranged on the periphery of springs of cylindrical shape. It is installed in a cast-iron cast-iron crankcase. It is intended for a short separation of the engine crankshaft with the gearbox, as well as their smooth connection at a time when the car starts moving and with further switching speeds.

You need to know how to properly adjustadhesion, i.e. check it, lubricate the drive and the squeeze bearing following the lubrication card. It is necessary to regularly monitor the tightening of the fixing bolts of the clutch housing with the flywheel crankcase. The tightening should be 8-10 kg. This should be done by uniform movements, with a sequence of cross-wise. After tightening the bolts, you must fasten them by deflecting the tines of the locking plates on the sides of the bolt heads.

Clutch and drive adjustment

The rules for the operation of the MAZ car include such adjustments:

adjusting the size of the departure value of the drive medium disk, which provide the necessary clearances of the working surfaces of the clutch after it is turned off
adjustment of the clearance value of the end face of the valve body cover and the adjusting nut
Clutch pedal adjustment
It will take a set of keys (carob and cap) and a ruler with a caliper.

Steps of adjustment

To carry out the full adjustment of the clutch,First, you need to adjust how far the average leading disk goes. This will ensure the necessary clearance of the working surfaces of the clutch. In addition, it is necessary to adjust the clearance of the end cap of the valve body and its adjusting nut, then adjust the operation of the clutch pedal.
Next, you need to determine how to remove the averagedrive the drive, removing the manhole covers from the clutch and flywheel clutches. To do this, you must turn on the clutch and set the neutral position of the gearbox. Then rotate the engine flywheel by screwing the four adjusting screws to the middle drive wheel to the very end. Beforehand, it is necessary to unscrew the locknuts on the screws.
Without stopping to turn the flywheel, it is necessary to turn it awayone turn adjustment screws and secure them with locknuts. By tightening the locknuts, do not apply great effort, and it is best to hold the adjusting screw, to avoid displacement of the adjusted clearance.
We measure the gap between the butt of the backthe cover of the valve body and the adjusting nut, which should be from 3.3 mm to 3.7 mm. Control the size of the gap after each TO-2. Adjusting this is done by loosening the lock nut and setting the correct gap. After this, tighten the locknut without breaking the installed clearance.
The next step is how to adjustclutch pedal. To do this, you need a ruler, with which, after the air is released from the pneumatic system, you will need to measure the amount of the pedal travel. It should correspond to 34-43 mm. The free-wheeling control should be carried out after each TO-1. Before this, it is necessary to make sure that the gap established before is normal.
To regulate the free running of the pedaldisconnect the pedal's two-arm actuator lever with the valve stem plug and the clutch cylinder stem. At the same time, move the piston of the cylinder to the very bottom, and lower the edge of the two-arm lever in the opposite direction until it stops. It must be checked that the fork holes of the cylinder rod and the lever are not aligned by about 50%. When deflecting to a greater or lesser side, it is necessary to bring to the required size by rotating the cylinder rod.
The final stage of how to adjustgrip on the Maze, will link the lever and all the disconnected elements, adjust the distance between the holes of the forks by rotating the forks themselves. It will be difficult to do this with a large wear of the friction linings of the disks. In this case it will be necessary to rearrange the two-arm lever by 1 slot in a counter-clockwise direction. Then re-adjust the clutch pedal travel.
