Weichai Deutz engine oil pump assembly 13039311 for TD226B / TBD226B / WP6 / WP4 engine
This pump is a gear-type oil pump, responsible for drawing oil from the oil pan and pressurizing it to deliver it to various lubrication points in the engine (crankshaft, camshaft, pistons, turbocharger, etc.), ensuring sufficient lubrication, cooling, and cleaning of the engine under high load and prolonged operation.
Function
1. Oil circulation and pressurized supply: Oil is drawn from the oil pan, filtered, and then pumped at a certain pressure (usually 0.4–0.7 MPa) to the main oil gallery and branch oil galleries, lubricating critical friction pairs such as crankshaft bearings, connecting rods, piston pins, camshafts, rocker arms, and turbochargers.
2. Maintaining stable engine lubrication system pressure: Sufficient oil pressure is maintained under various operating conditions, including idling, low speed, high speed, and heavy load, to prevent serious malfunctions such as dry friction, bearing seizure, and shaft damage.
3. Oil cooling and cleaning assistance: The pumped oil simultaneously carries away heat and flushes away impurities, working in conjunction with the oil cooler and filter to extend engine life.
4. Supports the needs of turbocharged engines: Specifically designed for Weichai WP6G/WP4G series (125–175 horsepower range), meeting the higher lubrication requirements of turbocharged and intercooled engines.

2.Weichai Deutz TD226B/TBD226B series (WP6G125E22, WP6G175E22, etc.) are used in loaders (such as Liugong, Lingong, Longgong), excavators (some medium and small models), forklifts, and generator sets.
3.Commonly used in construction machinery: Diesel engine power systems for brands such as SDLG, XCMG, and SANY.
4.Power range: Approximately 110–220 kW (150–300 horsepower) medium-sized diesel engines.
Symptom
1. The engine oil pressure is significantly low or drops suddenly to 0, and the gauge needle barely moves or fluctuates wildly. The pressure warning light stays on or flashes frequently, accompanied by a buzzer alarm.
2. A metallic knocking sound is heard after the engine starts, clearly coming from the oil pan/pump area, and is more noticeable when the engine is cold or accelerating.
3. Engine power decreases, acceleration is sluggish, black/white smoke is emitted, and the exhaust temperature rises abnormally.
4. A large amount of oil mist is ejected from the oil filler cap or crankcase, accompanied by a distinct "popping" sound of blow-by gases, and the crankcase pressure increases.
5. Accelerated engine oil consumption, with a rapid decrease in oil level on the dipstick in a short period.
6. Overall engine temperature is higher than normal, with the coolant temperature 5–15℃ higher than usual.
7. Oil leakage or oil stains at the oil filter/cooler, and oil traces appearing on the pump mounting surface.
Troubleshooting suggestions
1. Immediate replacement: When severe symptoms such as a sudden drop in oil pressure/constant warning light, abnormal noise, and poor performance occur, stop the engine immediately to avoid major damage such as bearing failure, crankshaft seizure, or cylinder scoring.
2. Replace as soon as possible: If the pressure remains consistently low, there is noticeable abnormal noise, rapid oil consumption, and frequent warning lights, schedule replacement within 1-2 weeks.
3. Preventive replacement: If there are no obvious symptoms, but the engine has accumulated 8000–12000 operating hours (approximately 4–6 years, depending on overload/operating conditions) or during major engine overhauls (such as simultaneous repair of cylinder liners and crankshaft), replace it at the same time. Under long-term high-temperature/severely polluted operating conditions, consider replacement earlier, at 6000–8000 hours.
