Installation & Application Notes

Always match seal material to fluid type — NBR for petroleum, FKM (Viton) for high-temperature/chemical applications. Lubricate seals with clean fluid before fitting — never grease. Check shaft surface for scoring — rough surfaces destroy new seals within hours.

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 speed fluctuations, particularly noticeable at idle or under changing load conditions, are the first signs of governor issues. If left unaddressed, the engine may become difficult to start, lose significant power, or operate unpredictably. This can lead to inefficient operation and potential damage to other engine components due to improper fueling.

Installation Tip

Ensure all governor linkage points are clean and free of debris before disassembling the governor. Avoid overtightening any adjustment screws, as this can disrupt the governor's calibration.

Service Note

Inspect the governor linkage, springs, and actuator for signs of wear or binding when replacing seals and components in this kit.
