11.1 Preparatory Information
Operation Precautions:
After disassembling fuel pump, clean the parts carefully and blow the surfaces of parts using high-pressure gas.
During the disassembly of fuel pump, do not drop the foreign body into the crankcase.
Function of lubricating system: The function of the lubricating system of engine is to provide
lubricant to the friction surface of workpiece to make the dry surface friction become into the liquid
friction between lubricant particles so as to reduce the wear of parts; cool the parts with high heat
loads; absorb the impacts of bearing and other parts and reduce noise; increase the sealability
between the piston ring and cylinder wall; clean and remove the impurities on the surfaces of parts.
