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

Erratic engine idle speed, such as surging or stumbling, is a common initial symptom. If left unaddressed, the engine may exhibit poor throttle response, difficulty maintaining speed under load, and increased exhaust emissions. The risk is inconsistent engine operation, potential stalling, and reduced overall productivity.

Installation Tip

Ensure the governor linkage is correctly synchronized with the throttle control before final assembly. Incorrect linkage adjustment can lead to immediate drivability issues or damage to the governor mechanism.

Service Note

Inspect the unit injectors and fuel lines for any signs of leaks or wear when replacing the governor.
