ap63402-ap63401-122-5053 Oil Pump Solenoid Valve — Cat 3126 322C

This is an Oil Pump Solenoid Valve, a critical component within the engine's lubrication system that precisely controls oil flow and pressure. It ensures optimal engine performance by regulating the oil pump's output based on operating conditions, preventing damage from insufficient or excessive lubrication. Failure typically manifests as erratic oil pressure readings on the dash, potential engine knocking sounds due to poor lubrication, or illuminated oil pressure warning lights.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing oil pump solenoid valve is often inconsistent oil pressure readings or a warning light. If ignored, this can lead to increased engine noise and reduced power as lubrication becomes inadequate. Prolonged operation with a faulty valve risks severe internal engine damage due to wear.

Installation Tip

Ensure the engine oil is at a safe level before starting to prevent oil loss during removal. Avoid overtightening the valve body, as this can damage the threads or the valve seat.

Service Note

Inspect the engine oil filter for metal particles, which could indicate internal wear.
