Toyota Oil Pump Assembly – Original Engine Oil Pump Replacement Wholesale
Genuine Toyota Oil Pump Assembly – Complete Engine Oil Pump for Camry, Corolla, RAV4 & Hilux
Overview – The Heart of Your Toyota Engine's Lubrication System
The oil pump is the heart of a Toyota engine's lubrication system. It draws oil from the sump and delivers it under pressure to every critical bearing surface — crankshaft, camshafts, pistons, and turbocharger. A failing Toyota oil pump causes low oil pressure, triggering dashboard warnings, valve train noise, and ultimately catastrophic bearing seizure.
We supply genuine Toyota oil pump assemblies covering popular Toyota engines, including the 1ZR, 2ZR, 2AZ-FE, 1KD, and 2KD series. Each original Toyota engine oil pump is supplied as a complete, ready-to-bolt-on unit — pre-assembled with:
- Pump housing
- Gears or rotors
- Drive shaft
- Pressure relief valve (factory-calibrated)
- Oil strainer
- Mounting gaskets

Gear-Type vs. Gerotor-Type – What's the Difference?
Our inventory covers both gear-type and gerotor-type oil pumps, exactly as originally fitted to each specific engine.
- Gear-type pumps use two meshing gears to displace oil. They are robust, simple, and commonly found in older Toyota engines.
- Gerotor-type pumps use an inner rotor and outer rotor with a slight eccentricity. They offer smoother oil flow, higher efficiency, and are more common in modern Toyota engines.
Using a genuine Toyota complete oil pump assembly eliminates the risk of mismatched components and ensures the precise rotor-to-housing clearance required for stable oil pressure across the full RPM range.
Why Source From SC INDUSTRY?
- Engine-Code Precision Matching – We match every oil pump by your Toyota engine code and production date. Mid-production changes in pump design are common, and using the wrong variant can cause low pressure or fitment issues.
- Complete Assembly, Ready to Install – Each genuine Toyota oil pump arrives pre-assembled with strainer, relief valve, and gaskets. No transferring old components, no missing parts.
- Technical Screening Before Dispatch – Our team checks your order against the engine code. If a pump variant does not match — such as a 2ZR pump ordered for a 2AZ engine — we flag it before shipping.
- Deep Stock on High-Failure Items – Oil pumps for 1KD and 2AZ engines are held in depth. When your workshop is mid-rebuild, we ship the same day.
