Overhaul points of trailer accessory traction seat:

1. During the first level maintenance, check all parts of the traction seat, check the wear of traction pin, traction pin plate, semi horizontal shaft and other parts, and lubricate all parts.

2. Pay attention to check whether there are cracks and severe wear on the traction seat itself. If there are cracks or severe wear that causes the traction seat to be deformed or too thin, replace it with a new one.

3. Check and tighten the bearing seat bolts, and replace the bolts if necessary;

4. Check the lock hole, and use the traction pin for fit detection. If the wear exceeds the limit, resulting in large fit clearance, it can be repaired by surfacing and machining to the required size, or replace the lock hook, lock block and wear ring for repair.

5. Adjust the fit clearance between the locking hook and the traction pin by adjusting the screw, and then lock it with the nut. If the fit is loose, replace the rubber elastic shaft sleeve. Then drive the tractor forward to complete the decoupling of the semi-trailer. Before decoupling, put down the supporting device of the semi-trailer.
