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

Initial symptoms of a failing fuel injection pump often include difficulty starting the engine, especially when cold. As the problem worsens, engine power will decrease, and excessive black smoke may appear in the exhaust due to incomplete combustion. Severe pump failure can lead to stalling and inability to run the engine.

Installation Tip

Ensure the fuel system is properly bled of air after installation to prevent starting issues. Avoid introducing any contaminants into the fuel system during the installation process.

Service Note

Replace the fuel filter and inspect all fuel lines and seals for leaks or damage when installing a new injection pump.
