(1) Clutch abnormal noise
Phenomenon: making an unusual noise or when the car clutch engagement
The reason: lack of lubricant bearings, or bearing damage caused by dry friction; no space between the inner end of the release bearing and release lever; oil and greasy dirt between the release bearing sleeve and the catheter serious or release bearing return spring and pedal return spring fatigue, broken off, so that the poor return bearings; driven plate spline hole splined shaft with its rattling; annealing driven disc damper spring fatigue or broken; driven disc friction plate rivets loose or loose rivets or rivet head exposed; pin hole double-plate clutch drive pins with the intermediate pressure plate and the pressure plate wear open.
Diagnosis and exclusion: slightly depress the clutch pedal to release bearing contact with the release lever, if there is "imperfections" sound was bearing abnormal sound, abnormal sound still if refueling, indicating excessive bearing wear, Songkuang damaged, should be replaced; step By lift the clutch pedal, if there is intermittent sound of the collision, indicating that ran before and after release bearing, replace the release bearing return spring; even pedal, there was a noise just engaged or if the clutch just separated, indicating loose rivets driven disc or exposed, replace driven disc
(2) Automotive clutch is not complete
Phenomenon: the engine idling, the clutch pedal, gear Guadang crash and difficult to hang in, if reluctantly put, when the clutch pedal is not yet fully relax completely turn off the engine.
Cause: The clutch pedal free travel is too large; separation lever bending, bearing looseness, bearing axle pin emerge so that the internal separation lever end height difficult to adjust; separation lever to adjust properly, it is not in the same plane inner end or inner end height too; improper dual-plate clutch intermediate pressure plate limit screw adjustment, individual separation spring fatigue, lack of height or broken, intermediate pressure plate on the drive pin or axial movement is not flexible in the clutch drive window; follower plate steel Alice song, broken or loose rivets friction plate; new for the driven disc friction plate is too thick or reverse installed wrong; follower plate spline hole and the transmission of the first shaft spline shaft cassette; hydraulically operated clutch mechanism oil spills, air or fuel shortage; diaphragm spring force weakened; the engine mounts for wear or damage to the engine crankshaft and the transmission input shaft misalignment.
Diagnosis and exclusion: Check auto clutch pedal free travel, free travel if adjustment is too large, the hydraulic control mechanism to check whether the storage tank fuel shortage or air pipe and make the necessary exclusion; internal inspection height separation lever end If separation lever is too low or not in the same plane, then make adjustments, or check driven disc anti-loaded, no problem if you continue to check; check driven disc if warpage rivets off, whether driven axial movement of the cassette tray If the replacement or repair. |
