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 indication of a problem might be a slight shudder or vibration during acceleration or load changes. If the key is damaged or missing, it can lead to intermittent loss of power transmission and increased wear on the shaft and mating component. Failure to address this can result in complete slippage and potential damage to the connected components.

Installation Tip

Ensure the keyway in both the shaft and the mating component are clean and free of burrs or debris before installation. Never force the key into place; it should seat smoothly.

Service Note

Inspect the shaft and the mating component's hub for any signs of wear, scoring, or damage where the key seats.
