Description
Product Overview
The VP44 electronic control distribution pump is widely used in light trucks and medium/large agricultural machinery. It achieves high-pressure oil supply through an electronic control distribution structure. Under long-term conditions such as high cabin temperature, prolonged diesel exposure, and impurities erosion, various rubber seals harden and expand, metal gaskets are compressed and deformed, and oil circuit filter components get clogged. This can lead to oil pump main shaft leakage, fuel internal leakage diluting the engine oil, insufficient equipment power, idle wobble, and difficulty in starting after engine shutdown. This maintenance package covers all sealing components of the pump head, main shaft, metering valve, outlet, and low-pressure oil chamber, with dimensions fully matching the internal structure of the VP44 oil pump. All worn parts can be replaced at once during major repairs, significantly extending the service life of the oil pump as a whole. It is suitable for maintenance and servicing of VP44 distribution pumps for light commercial trucks, tractors, and small construction machinery.
Core Advantages of the Package
Multiple sizes and colors of fluorine rubber O-rings, covering all sealing points of the oil pump's oil channels
Equipped with black, green, and purple multi-sized oil-resistant sealing rings, suitable for different sealing positions of the low-pressure intake chamber, pump head, metering valve, and pressure regulating valve. The fluorine rubber material is resistant to diesel, high and low temperatures, and is not prone to hardening and leakage under long-term oil pressure impact, effectively blocking the internal return of fuel and pressure relief.
Thickened brown main shaft frame oil seal, effectively curing the leakage of the drive shaft
Integrated double-layer pressure-resistant frame oil seal, assembled at the main shaft installation position, suitable for the reciprocating motion of the shaft body, double-layer blocking the main shaft gap leakage, avoiding diesel flowing into the gear chamber and diluting the lubricating oil.
Green pump head sealing gasket, no leakage at the pump body joint surface
Overall formed green sealing pad, fittingly adhering to the joint plane of the pump head and the housing, filling the fine gaps of the plane, completely preventing high-pressure fuel from leaking out through the joint of the housing.
All purple copper sealing pads, long-term sealing of oil circuit threads
Multiple-sized purple copper flat washers match the high-pressure oil outlet connector and pressure regulating screw installation positions, with a soft and hard texture that is not prone to crushing and cracking after tightening, and no oil leakage or pressure relief under high-pressure conditions.
Multiple-sized white oil circuit protection plugs, for maintenance protection of precise oil circuits
Complementary multiple plastic sealing plugs, sealing various oil ports during oil pump disassembly and maintenance, preventing dust and impurities from entering the cavity and scratching the distribution rotor and piston, reducing assembly rework rate.
Rectangular metal positioning tabs, fixing the internal oil circuit distribution structure
Black long-strip oil circuit positioning tabs, after assembly, limiting the internal oil path components, preventing components from shifting in vehicle bumpy conditions, ensuring uniform and stable fuel supply for each cylinder. List of Accessories
