10. 1 Service Data
Function of lubricating system: engine lubricating system is to supply lubrication oil to friction
surface of engine elements, turning the dry friction on the surface into liquid friction between
lubrication oil particles, thus mitigating part wearing, cooling down parts with high thermal load,
absorbing impact from bearing and the elements and consequently reducing noises, increasing
tightness between cylinder ring and wall, and cleaning and taking away foreign matters from
surface of parts.
Precautions
After engine oil pump is disassembled, carefully clean its parts and purge the surface with
high-pressure gas.
To disassemble engine oil pump, it is important to prevent any foreign matter from falling into
crankcase.
