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 tacho-generator is often an inaccurate or fluctuating tachometer reading on the operator's display. If left unaddressed, the engine control unit may receive incorrect speed data, leading to performance issues or engine shutdown. This can ultimately prevent the equipment from operating effectively and safely.

Installation Tip

Ensure the mounting surface on the engine block is clean and free of debris before installation to achieve a proper seal and accurate sensor reading. Avoid overtightening the mounting bolts, as this can damage the generator housing or the engine block threads.

Service Note

Inspect the engine's wiring harness for any signs of damage or corrosion, and check the engine control unit (ECU) for any related diagnostic trouble codes.
