What are the early primary extrusion gear pump wear is the reason?
Early primary extrusion gear pump wear main reasons: the backlash main, driven spiral bevel gear and Helical Gear too small; improper tooth contact position adjustment; maintenance or repair, the addition of a substandard quality of lubricating oil; each bearing preload adjustment too tight, the process of moving heat caused by high oil temperature, oil viscosity decreased;
Rear axle housing vent hole is blocked at working temperature inside the axle housing so that the pressure increased, forcing the lubricating oil from leaking at each gasket; rear axle final drive housing and connecting bolts loose, the lubricant sink drain; diesel long-term car overloaded or speeding, repair and assembly process mixed with dirt and so on.
