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

Visible signs of failure include cracks, severe dents, or missing sections of the guard. If the guard is compromised, the underlying components become exposed to impacts and debris, leading to accelerated wear or damage. Continued operation without adequate protection risks significant mechanical failure of the exposed parts.

Installation Tip

Ensure all mounting surfaces are clean and free of rust or debris before attaching the guard. Do not overtighten fasteners, as this can strip threads or deform the guard.

Service Note

Inspect the components being protected for any signs of damage or excessive wear that may have occurred prior to guard replacement.
