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.

Installation Tip

Thoroughly clean the bearing bore and shaft, ensuring they are free from any contaminants or burrs before installation. Avoid hammering or applying uneven pressure when seating the bearing.
