In the long working process of diesel engine, the main operation of the cam shaft is the shaft neck wear, cam surface wear and cam shaft bending, etc..
(1) shaft neck wear
Mercedes Benz accessories in the north of Baotou in the long-term use of the camshaft will be worn. With the increase of wear, the gap between the shaft and the bearing will be increased, the quality of the diesel engine will become worse, and the engine oil pressure of the diesel engine will be reduced. Under normal circumstances, the wear of the shaft neck is generally small.
(2) cam surface wear
Main causes of wear of cam is: Baotou North Benz parts surface of the cam tappet and push rod by cyclical shocks, and cam and tappet contact area is small, the stress of the unit area is larger, and the deterioration of lubrication condition, so the diesel engine in the long time or overload prone cam wear phenomenon.
(3) cam shaft bending
The cam shaft bending of the Mercedes Benz parts in the north of Baotou is generally caused by the collision between the piston and the valve or the valve stuck in the cylinder.
