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 oil seal is typically a visible oil leak around the shaft where the seal is located. If ignored, the leak will worsen, leading to a significant loss of engine oil and potential lubrication issues. Continued operation with a leaking seal can cause excessive wear on engine components due to insufficient lubrication.

Installation Tip

Carefully clean the sealing surface on the shaft and the housing bore to ensure a perfect seal. Avoid using excessive force or sharp tools when pressing the seal into place, as this can damage the seal lip.

Service Note

Inspect the shaft for scoring or wear where the seal rides; replace the shaft if damaged.
