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

Early signs of failure may include whining or grinding noises from the hydraulic system or drive train, and a potential decrease in operational speed or power. If left unaddressed, the bearing can seize, leading to damage to the hydraulic pump, motor, or drive axle. This can result in significant repair costs and extended equipment downtime.

Installation Tip

Ensure the bearing bore and shaft are meticulously cleaned and free of any debris or old lubricant before installation. Avoid applying excessive force or heat to the bearing, which can alter its internal clearances and compromise performance.

Service Note

Inspect the hydraulic pump/motor shaft, housing, and any associated seals for wear or damage during the bearing replacement.
