WEICHAI WP12 ENGINE Oil Pump Assembly 612630010256 FOR SINOTRUK HOWO TRUCKS
FUNCTION
1. Continuous Pressurized "Blood" Delivery: It draws engine oil from the oil pan and, through the high-speed compression of internal precision gears, generates pressure reaching hundreds of kilopascals to forcefully pump the oil into the engine's main oil galleries.
2. Comprehensive Forced Lubrication: It precisely delivers high-pressure oil to all high-speed friction surfaces-including crankshaft bearings, connecting rod bearings, camshafts, valve rocker arms, and turbochargers-forming a robust oil film that transforms "dry friction" into "fluid friction," thereby preventing engine wear.
3. Cooling and Heat Dissipation: Through a high-flow oil circulation system, it carries heat away from high-temperature zones-such as piston crowns and cylinder liners-back to the oil pan; here, the heat is dissipated via the oil cooler, assisting the coolant in the vehicle's overall cooling process.
4. Cleaning and Debris Flushing: It utilizes the flushing force of the circulating oil to wash away microscopic metal particles, carbon deposits, and sludge generated by internal engine friction, transporting them to the oil filter for removal and thereby maintaining the internal cleanliness of the engine.
Recommended Companion/Wear Parts for Simultaneous Purchase
1. Oil Pump Gasket (Seal): 612600150005 - A metal-composite sealing gasket situated at the junction of the oil pump and the cylinder block; essential for preventing oil leaks at this location, which could otherwise lead to a drop in oil pressure.
2. Oil Pump Drive/Intermediate Gear: 612600020354 - The oil pump intermediate drive gear assembly, responsible for power transmission within the engine's gear chamber.
3. O-rings and Oil Seals: High-temperature-resistant fluororubber O-rings designed for use on the flanges of the oil inlet and outlet lines.

Common Faults and Replacement Indicators
1. Oil Pressure Warning: When the engine is warm or idling, the red oil pressure warning light on the dashboard flashes or remains continuously illuminated.
2. Abnormal Metallic Noises: If the internal gears of the oil pump are excessively worn, have chipped teeth, or if the bearings are damaged, a metallic knocking sound will emanate from the pump housing area.
3. Presence of Metal Shavings in the Oil: During an engine overhaul or oil change, if a significant amount of fine iron shavings is found adhering to the magnetic drain plug in the oil pan, it may indicate abnormal wear of the oil pump or that the pump has begun to "scour" its housing.
