How to maintain the automobile clutch bearing because of the long-term exposure of the separation bearing, the lubrication condition is very poor, so after 300 to 500 hours, the tractor should remove the separation bearing, clean it with diesel and make it turn flexibly, then heat it into the butter container until the butter is filled with the bearing and pending cooling. After the solidification, take out and install it. The separation claw and the bearing cover spiral bevel should be often scrubbed clean and lubricated with oil or butter, and often to separate the small oil hole oil on the separation claw to lubricate the separation claw and separate the claw seat. When the friction plate, the active plate and the press plate are contaminated with oil or rust on the clutch, the removal or oil should be removed and cleaned with gasoline or kerosene, and then dried and installed. After cleaning or replacing the clutch bearing, the clutch bearing should be coated with a proper amount of butter and make one side with a dust cover face to the clutch, not to be installed in the clutch, preventing the oil from flowing into the clutch and making the clutch slippery. Adjust the clutch control mechanism regularly, clear the soil, tighten all the connecting bolts, and lubricate the clutch pedal axis according to the regulations. New friction plates should be replaced when the rivet head is discovered, and the cracks, breakage, large area burning and the wear of each piece of friction plate are less than 3.4 millimeters in thickness.
