1512154020 Toyota GEAR, OIL PUMP DRIVE, Price: 20.35$, Weight: 0.206kg

Oil Pump Drive Gear for Toyota Engines ⚙️

Why this part is needed

This gear sends crankshaft motion to the oil pump, building the oil pressure that feeds bearings, camshafts, and valve train. Without a healthy drive, the lubrication system cannot protect the engine. It is a small part with a huge job, critical for long service life and quiet running.

How it works ️

The hardened steel teeth mesh with the mating gear or shaft. As the crank rotates, the gear spins the pump at the correct speed, moving oil through galleries to every friction point. Precision tooth form keeps noise low and pressure stable at idle and high RPM. Heat-treated core and accurate bore keep alignment true under load.

What happens if it fails

Warning lamp for low oil pressure, ticking lifters, rough idle, and metallic rattle may appear. Continued driving can wipe crank and rod bearings, score cams, overheat pistons, and in worst cases seize the engine. Metal dust in oil is common after tooth damage.

Quality and fitment

OE-spec material, precision machining, and shot-peen hardening for long wear. Built for selected Toyota gasoline and diesel engines; always confirm by VIN, engine code, and tooth count.

Installer notes ✅

Inspect the oil pump, mating gear, chain/drive, and relief valve. Align marks, set torque, and pre-lube the pump. Replace seals and pan gasket, change filter, and fill with correct-grade oil. After start, verify pressure and check for leaks.
