113-1141 Oil Pump Assembly — Cat 3046 3044C

This oil pump assembly is vital for circulating lubricating oil throughout the engine, maintaining oil pressure and ensuring all moving parts are properly lubricated. Built to OEM specifications, it provides reliable oil flow and pressure, unlike a worn pump that may deliver insufficient lubrication. Operators might observe a fluctuating or low oil pressure warning light, increased engine noise, or signs of premature wear on engine components if this assembly fails.

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 primary symptom of a failing oil pump is a drop in engine oil pressure, often indicated by a warning light or gauge reading. If ignored, this can lead to inadequate lubrication of critical engine components, causing increased friction and heat. Prolonged operation without proper lubrication will result in severe internal engine damage.

Installation Tip

Ensure the oil pickup tube screen is clean and properly sealed to prevent air from entering the lubrication system. Do not overtighten the oil pump mounting bolts, as this can distort the pump housing.

Service Note

Always replace the engine oil and oil filter when installing a new oil pump assembly.
