Inspection method of clutch driven plate
(1) Detect the wear of the driven disc friction plate
Measure the depth of the rivet head with a vernier caliper to check the wear of the friction plate. If the depth is less than 0.3mm, it means that the wear is serious and the friction plate should be replaced.
(2) Detect the deformation of the driven disc
The degree of deformation can be checked by the deflection of the driven disc, and the circular runout of the end face of the driven disc shall not be greater than 0.4mm when measured on the peripheral edge of the driven disc with a dial gauge. If the circular runout of the end face exceeds 0.4mm, use the wrench to correct the driven plate or replace the driven plate assembly. Otherwise, it will cause the clutch to shake when the car starts; the clutch is not completely separated, and the gear shift is difficult.
(3) Detect the connection between the driven disc steel sheet and Yi
It can be tested by tapping with a hammer. If the rivet is loose or broken, replace it.
(4) Detect the matching clearance between the driven disc spline shaft sleeve and the transmission input shaft spline shaft
If the gap is too large, it will affect the start of the car or the sound when the speed changes suddenly. During the test, the driven disc spline shaft is sleeved on the first shaft spline of the gearbox, and the driven disc is rotated back and forth by hand. No significant looseness is allowed. If the tooth side clearance exceeds 0.16mm, the driven disc hub or gearbox should be replaced. Input shaft.
