How to adjust the clutch MAZ

To do a full clutch adjustment adjust the amount of secondary waste from the master drive to provide the proper clearance between the working surfaces of the clutch. Also adjust the gap between the end of the valve body cover and its adjusting nut and the adjustment of the clutch pedal.

Adjust the amount of the waste medium master disk, after dismantling of manhole covers to the clutch and flywheel housing. To do this, engage the clutch and set the gear lever in neutral gear position. Then start to rotate the engine flywheel, at the same time vvorachivaya until it stops in the middle drive plate, four adjusting screws, turning them in advance of the locknut.

Then, continuing to rotate the flywheel, loosen the adjustment screws one turn and tighten the lock nuts. When tightening jam nuts holding tool adjusting screw to avoid axial play and do not apply significant force to the lock nut.

Measure the clearance between the end face of the rear valve body cover and adjusting nut. It needs to be 3.3 to 3.7 mm. Control the size of the gap after each to-2. To adjust it, loosen the lock nut the adjusting nut, set the desired size of the gap and tighten the locknut, trying not to disturb the exposed gap.

To check pedal free play clutch take a ruler, pull the air from the pneumatic system and measure the amount of pedal travel before the appearance of typical efforts. The measured value should be equal 34-43 mm. Control free play whenever-1. Prior to inspection make sure the gap between the end face of the rear valve cover and adjusting nut (item 4) is correct.

To adjust the free pedal travel, disconnect duplici lever pedal linkage from the fork of the valve stem and the plug stem of the clutch slave cylinder. The cylinder piston move to its lowest position, the lower end of duplicera arm slide back until it stops. Make sure the plug hole of the cylinder rod and the hole of the lever is not aligned by about 50%. If the holes are rejected at a much greater or a much smaller quantity, bring the misalignment by rotating the cylinder rod to the desired size.

Then connect duplici arm with all the disconnected elements and the distance between the holes of the forks adjust the rotation of the forks themselves. If the friction linings of clutch disks are worn, to change the distance between the forks of the stem would be impossible. In this case, duplici remove the lever from the shaft the release fork and move it 1 spline counter-clockwise. After that re-adjust the free travel of the clutch pedal.
