On the Baotou North Benz accessories camshaft common faults and causes:

Diesel engine in the long-term work process, the camshaft main operation has journal wear, cam surface wear and camshaft bending.

(1) journal wear

Baotou North Benz accessories cam shaft journal in the long-term use will appear wear and tear. With the increase of the wear amount, the cooperation gap between the journal and the bearing will increase, the quality of the valve of the diesel engine will be worse, and the oil pressure of the diesel engine will be reduced. Under normal circumstances, the journal wear is generally small.

(2) cam surface wear

The main reason is that the cam surface is affected by the tappet and the putter periodic impact, and cam and tappet contact area is small, the larger the force per unit area, coupled with the deterioration of the lubrication conditions, so the diesel engine in the Long or overload operation is easy to cam wear phenomenon.

(3) camshaft bending
