FWA J6 FAW J5 FAW JH6 TRUCK Oil Pump Assembly 1011010-81D suitable for XICHAI CA6DM2 engine

It is responsible for the oil circulation of the engine lubrication system and provides sufficient oil pressure to each friction pair, making it the core lubrication component of the engine.

FUNCTION

1. Provides High-Pressure Oil Circulation: As a high-pressure gear-type oil pump assembly, it draws oil from the oil pan and pumps it at high pressure to various lubrication points in the engine, including main bearings, connecting rod bearings, camshafts, piston cooling nozzles, and turbocharger bearings. This ensures adequate lubrication of all friction pairs in heavy-duty diesel engines under high loads and high torque, preventing dry friction and excessive wear.

2. Maintains Oil System Pressure: A built-in pressure relief valve automatically relieves pressure when the oil pressure is too high, preventing pipe rupture or seal failure. It quickly builds oil pressure during cold starts, at low temperatures, or at high speeds, protecting lubrication during engine startup.

3. Supports the Needs of Large-Displacement, High-Power Engines: The CA6DM2 series operates under high thermal and mechanical loads. Designed with a large flow rate and strong pumping capacity, it can handle the high fuel consumption demands of long-distance heavy-load and uphill driving conditions. The gear pump structure provides high transmission efficiency and good noise and vibration control.

4. Auxiliary Cooling and Cleaning: After circulating through the pump, the engine oil enters the oil cooler, reducing its temperature and slowing down its aging process. Simultaneously, the oil is delivered to the filter for further cleaning of impurities, ensuring the cleanliness of the lubricating oil.

DETAILS

Common symptoms include: oil pressure warning light illuminating, abnormal noises, and oil leaks. These are usually caused by gear wear, a stuck pressure relief valve, or a clogged oil filter. Regularly replacing the oil filter (every 20,000–30,000 kilometers) and checking the oil pump are key maintenance points.
