Weifang 4100 turbine pump K4100ZH4100 pump rod and cylinder cover four facilities, high pressure pump, water pump, water tank, flywheel, flywheel shell, oil pan, oil pump, filter, filter, fuel filter, starter, generator, air filter, diesel filter, filter, main bearing machining accuracy poor. Because of the large deformation, caused by the connecting rod in the shaft neck on the side and center and the center cylinder gap, endless crank connecting rod mechanism do not coincide, cause partial wear of piston and cylinder wall, after running clearance increases the cylinder compression force
