Technical condition and traction control
After removing the clutch remove the product from the surface wear on the casing, discs and flywheel using only a special cleaner or methyl alcohol. Work is carried out in a respirator and goggles, as the dust is harmful to health. Wipe with a cloth soaked in gasoline, the inside of the flywheel and check the friction surface of the flywheel. If the friction linings slave drive to the rivet heads are worn out, it is quite possible that the damaged rivets working surface of the flywheel or the pressure plate. Check the pressure plate and clutch cover for damage, scratches, cracks, colored spots appeared from overheating or deformation. If damage is found, replace both parts in the assembly. Checking the status of the slave drive Check the condition of the friction linings. When oiling them, the appearance of cracks, uneven wear and unilateral bullies, as well as reducing the distance between the rivet head and the working surface of the pad up to 0.3 mm, replace the clutch disc to the next.

Make sure the damper spring clutch disc are not damaged, and the wedge engages not broken too much. To test the run-out drive plate put on a suitable mandrel and clamp it between the holders of a lathe (fig. 227). Replace the measuring instrument holder so that the measuring finger located opposite the drive plate edges, namely on the outer edge of the disk. Slowly turning the clutch disc, make sure the meter reading. If the runout of the working surface of the friction linings of more than 0.4 mm, then, if desired, can be carefully straighten it with pliers, or replace the clutch disc. Check the degree of wear of the friction linings are performed using the probe to measure the depth. Check the condition of the spline on the clutch disc on the gearbox input shaft, and clearance of the splined connection. If the gap is greater than 0.4 mm, the splined connection is worn. The reason for this is largely a slave drive. Check the wear of petals of the diaphragm spring

If the ends of the petals (Fig. 228) is the deep traces of wear, replace the housing assembly with the pressure plate. Traces generate all the petals of the diaphragm spring to a depth of up to half its thickness. Check the position of the petals of the diaphragm spring. Deviation petals from one plane should be less than 0.5 mm. If large deviations from the plane, you can slightly bend the petals with a special tool or a slotted metal strip. Checking the deformation of the working surface of the pressure plate The surface of the pressure plate to be checking for warpage using a metal ruler (timber) and the probe.

|
Place a metal ruler on the working surface of a press disk (Fig. 229) and using the probe to measure the gap between the plane of the work surface and line. Pressure plate with inward deflection of less than 0.3 mm can be used in further operation. Checking release bearing Check filmed release bearing, paying particular attention to the smoothness of its rotation, play and wear tracks.
A warning Remove the bearing can only wipe, but do not rinse. |
Bearings should be checked by hand. It must be easy to rotate and not to make noise. Pay special attention to bearings, which have been commented on noise at the time of the clutch (pedal). Increased noise when you turn off the clutch release bearing fault characteristic.
Note It is recommended to replace the release bearing together with the clutch plate. |
