1, before the installation of oil pump, to check the model, the specifications are correct, and remove the rust-proof oil, the gasket thickness should be appropriate to prevent overbooking or too thick and the piston to death or not in place, tighten the bolt tightening torque Even, to prevent damage to the pump. 2, the oil filter joint coarse filter core easily easily clogged with cotton and other dirt, should always check the cleaning, filter damage must be promptly repaired or replaced. 3, hand pump on the oil pump piston and hand oil pump body between the rubber seal, do not arbitrarily move, rubber damage to the timely replacement. 4, after the hand pump must be pressed back, the button tightened to prevent the hand pump and rubber ring or valve and seat pressure is not tight and lead to air or oil leakage. 5, to ensure that the plunger pump "spring" flexible and normal. "Four springs" for the piston spring, tappet (roller) spring, into the valve spring, the valve spring, the spring weakened or broken to be timely replacement or pad adjustment. 6, to ensure that intact gaskets everywhere intact, plastic washers disassembly times should not be too much, and should be replaced on a regular basis. 7, some pumps have a drain on the pump body, the role of the hole is to pump a small amount of diesel leaks directly out of the pump. Do not block the hole to prevent diesel from entering the pump sump to dilute the oil. 8, found that the fuel injection pump sump diesel too much, it is necessary to promptly check the transmission pump piston and pump body, tappet and tappet sleeve clearance is too large, too large to deal with in time to prevent serious diesel leaks, the fuel pump and transfer Poor lubrication within the mechanical parts. 9, a long time down, to prevent the pump with the mating surface, especially the piston and pump body, tappet and tappet suite corrosion due to water in the oil, rust prevention measures must be taken (shutdown, the replacement pump sump With water, diesel and other impurities in the oil). 10, the filling of diesel to be filtered through sedimentation to ensure clean, prevent excessive fuel and exacerbate the fuel pump into the valve, the valve out of oil, valve seat wear and tear, and sometimes the valve will be padded impurities and failure.
