Regularly check the camshaft clearance

Date:Jul 12, 2019

The axial clearance of the camshaft of the fuel injection pump is very strict, generally between 0.03 and 0.15 mm. If the clearance is too large, the impact of the roller transmission component on the working surface of the cam will be aggravated, thereby increasing the early wear of the cam surface and changing the supply. The oil advance angle; the camshaft bearing shaft and the clearance are too large, which may cause the camshaft to run unevenly, the oil amount adjustment lever is shaken, and the oil supply quantity changes periodically, so that the diesel engine is not running smoothly, so it is necessary to check and adjust periodically. When the axial clearance of the camshaft is too large, the gasket can be adjusted on both sides, and the radial clearance is too large, and it is generally necessary to replace the new product.
