1 The locknut on the valve clearance adjustment screw of this model is often loose, resulting in a series of adverse consequences. Therefore, in addition to the driver's own adjustment of the valve clearance, the trivial nut should be tightened. For new and overhauled locomotives, the locking of the nut should also be checked before and after the trial operation. 2 When adjusting the brake linkage mechanism, the trailer should be braked first and the main vehicle braked immediately. This is to prevent the trailer from colliding with the main vehicle and causing the control to run out of control. At the same time, the front and rear axles of the trailer should be adjusted to ensure that the front axle braking force is less than the rear axle braking force, otherwise the rear axle tires will be seriously worn. 3 Most of the Shanghai-50 tractors are a multi-purpose machine. When they are busy, they go down to the fields and transport them when they are busy. Therefore, the air pump is very important. The force acting on the piston, connecting rod and crankshaft in the air pump is intermittent, the air pressure is large, and the air intake force is small. The air pump adopts a jaw clutch. When the power is transmitted, the tooth is repeatedly impacted and the wear is rapid, and the impact noise after wear is large. This noise is like a knock on the engine. Do not misdiagnose it. Some Shanghai-50 tractors have relatively easy crankshaft wear and wear marks occur in one year. Whatever the cause of this, the user's attention to the cleaning of the oil will reduce the wear of the crankshaft shaft diameter.
