Key points of automobile transmission shaft maintenance:

During vehicle maintenance, the transmission shaft should be reinjected with grease and the connecting bolts of the transmission shaft should be tightened, which is very important for the running in period of new vehicles.

1. Before use, the transmission shaft must be filled with special automotive grease at the oil filling places such as universal joints, intermediate supports and sliding splines.

2. The lubrication of universal joints, intermediate supports and sliding splines must be checked every 7 days or 2000 kilometers. If the lubrication is poor, special automotive grease should be added. No. 3 lithium grease should be injected in summer and No. 2 lithium grease should be injected in winter.

3. It is strictly prohibited to start with high gear, violently lift the clutch pedal, overload, overspeed and other non-standard operations.

4. Because the fastening bolts of the transmission shaft are easy to loosen and fall off in the heavy-duty transmission environment, the daily maintenance of the transmission shaft is mainly to fasten the connecting bolts and add grease. When filling the universal joint, intermediate support, sliding spline and other parts of the transmission shaft with automotive special grease, the oil nozzle should be cleaned and unobstructed first, and the blocked or deformed oil nozzle should be replaced in time. The oil filling amount is subject to the overflow of new oil. Check the fastening of the bolts and nuts of the transmission shaft, especially the connecting bolts of the lug fork and the fixing bolts of the intermediate support bracket, which should be tightened according to the specified torque.
