Maintenance Of Clutch Release Bearing
How to judge and exclude the clutch release bearing sound?
Start the engine.
, gently step on the clutch pedal, when the clutch bearing and separation lever contact, hear a rustling sound, lift the pedal, the sound disappears, can be concluded for the clutch release bearing oil or poor lubrication and sound. such as stepping on the clutch pedal, emitting the metal dry friction sound, remove the clutch bottom bright, if see the clutch bearing and the separation lever contact with ablation discoloration marks, the clutch release bearing does not turn or damage. such as starting the engine, the Xin to intermittent bearing sound, Clutch Release Bearing hook up the clutch pedal, the sound disappeared, mainly the pedal back to the spring off the broken or soft, the pedal back to a bit. Sometimes, the clutch release bearing spring is too soft, elongate or broken off, will always hear the bearing sound.
Bearings are missing oil and should be added. If the bearing card is dead damaged or worn out, the new parts should be replaced.
The clutch release bearing is arranged between the clutch and the transmission, the clutch release bearing seat is loosely sheathed on the tubular extension part of the first shaft bearing cover of the transmission, Clutch Release Bearing and the clutch release bearing's convex shoulder is always offset by the return spring to the separating fork and back to the final position, and the separation lever end (separating means) maintains the 3~4mm left and right clearance.
Because the clutch pressure plate, the separation lever and the engine crankshaft synchronous operation, but the separation fork only along the clutch output axis axial movement, directly uses the separation fork to dial the separation lever obviously is not possible, Clutch Release Bearing the clutch release bearing allows the separation lever to rotate the a edge clutch output shaft to move axially, thereby ensuring that the clutch can be smoothly jointed, separated, softened, reduced wear, and prolonged the service life of the clutch and the entire driveline.
Clutch release bearing movement should be flexible, without sharp noise or stuck phenomenon, its axial clearance must not exceed 0. 60mm, the inner ring should not wear more than 0. 30mm.
Most of the domestic automobile clutch adopts the closed side-pressure ball clutch to release the bearing, and the most of the grease is calcium base grease and calcium-sodium base grease. Most maintenance personnel in the clutch release bearing lubrication, the use of lubricating oil and grease each 50% after the melting of the clutch release bearing into the oil to soak, so that it fills after the cooling method. Although this practice completes the raise task, but the effect is not good, because the heating will cause the calcium base grease the organization structure to destroy, Clutch Release Bearing causes the lubricating grease performance to drop, causes the clutch to release the bearing premature to wear, shortens its service life. The correct way is to raise with the injector. The high-grade car must use the imported lubricating oil.
(1) The engine does not disintegrate the oil injection method first opens the clutch cover, the view check clutch release bearing wear condition, if the bearing is not damaged or wear-free, then remove the clutch pedal, adjust the link shaft pin, so that the clutch release bearing and its seat back to the final position, with a sharp-nosed butter gun to the hole of the bearing seat to add butter, until the bearing oil spill, then slightly rotate the bearing, oiling again, repeat the above work until the bearing is surrounded by a little butter overflow, then make the bearing rotation, observe the oil volume, If there is resistance to the rotation of the bearing, it is proved that the bearing is full of butter. The clutch is then cleared to release the small amount of butter spilled from the bearing seat, and the removed pins and clutch lids are reassembled. (2) The oil injection method of engine disintegration exposes the engine to the clutch release bearing and the bearing seat's fitting, release the small oil hole under the inner ring of the bearing seat with the tip butter gun to the clutch to refuel, the bearing has the butter overflow to rotate the bearing, until the bearing circle all has the butter overflow to be possible. After the two methods are processed, Clutch Release Bearing the clutch release bearing can no longer refuel in half a year.
