Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of failure may include a grinding noise during operation or increased vibration. If left unaddressed, the bearing can seize, leading to component seizure and potential damage to surrounding drive train parts. Continued operation risks significant downtime and costly repairs to the drive system.

Installation Tip

Ensure the bearing housing is thoroughly cleaned before installation to prevent contamination. Avoid using excessive force or improper tools when pressing the bearing into its seat, as this can cause premature failure.

Service Note

Inspect the adjacent seals and shaft for wear or damage when replacing this bearing.
