The engine oil pump is the core lubrication power component of heavy-duty diesel engines, responsible for continuously conveying engine oil to crankshaft bearings, connecting rod bearings, pistons, turbochargers and all friction parts to form a protective oil film. Once the oil pump wears out, the internal gear clearance increases, resulting in insufficient oil pressure, engine abnormal knocking, turbo bearing burnout, and even cylinder locking under full-load climbing, bringing huge overhaul losses to fleet operators. Our OEM standard HG1500079010A gear oil pump is factory-matched for Sinotruk WD615 series engines, widely applied on HOWO A7, Steyr King Prince heavy trucks and matching wheel loader construction machinery, favored by global engine repair shops and spare parts wholesalersAlibaba.co….
This HG1500079010A integrated gear oil pump adopts cast iron pump body with integrated driving gear assembly, precisely matched to WD615 two-valve diesel engines (336hp, 371hp, 420hp). It maintains stable rated oil output under low and high engine speed, effectively solving common faults of inferior pumps such as slow oil pressure rise after cold start and pressure drop under heavy load. Many low-cost aftermarket oil pumps use thin cast pump bodies and low-hardness gears, which suffer rapid tooth surface wear, oil channel blockage and internal oil leakage after short-term operation in dusty working environments. Our product uses high-strength ductile iron shell and carburized quenched alloy gears, with stable clearance between meshing teeth, strong wear resistance and long-term stable oil supply performance.
All finished HG1500079010A oil pumps are manufactured strictly following original Sinotruk OEM casting molds, with fully consistent mounting hole positions, oil inlet/outlet calibers and gear tooth parameters. Maintenance technicians can complete direct bolt-on installation without trimming gaskets or modifying pipeline interfaces, greatly shortening engine overhaul labor time. The built-in pressure limiting valve automatically regulates lubricating oil pressure to avoid excessive oil pressure damage to sealing gaskets. Each pump passes oil flow test, pressure calibration and leakage inspection before leaving the warehouse to eliminate hidden lubrication failures after assembly.
Three core practical advantages make our HG1500079010A oil pump the preferred bulk purchase choice for global buyers. First, exclusive matching for classic WD615 engine platforms, compatible with HOWO heavy trucks and corresponding construction machinery, zero mismatching risk for cross-border export vehicles. Second, high-hardness gear and thickened pump body structure extend service life significantly, reducing engine overhaul frequency and long-term operating costs for transport fleets. Third, we maintain year-round sufficient spot inventory of HG1500079010A, supporting single-piece retail for emergency engine repair and tiered discount large-volume wholesale for regional distributors, neutral export carton packaging can be customized to meet local secondary resale demands1688阿….
HG1500079010A oil pump only fits Sinotruk WD615 series two-valve engines, it cannot be interchanged with four-valve WD615, MC11 or WP13 engine oil pumps. During engine overhaul, it is recommended to replace the oil filter, oil pan gasket and crankshaft oil seal together to form a complete lubrication system maintenance solution. If you cannot confirm engine compatibility, send us your truck VIN code or the OEM number marked on your old failed oil pump, our professional technical team will complete matching verification within 24 working hours.
Stable lubrication system is the fundamental guarantee of diesel engine service life. Cutting procurement costs by installing inferior oil pumps will lead to premature wear of all internal moving parts and expensive full-engine disassembly repairs. Our OEM-grade HG1500079010A oil pump balances reliable long-term lubrication performance and competitive wholesale pricing, providing stable engine overhaul spare parts solutions for global HOWO heavy truck and construction machinery operators.
