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

A failing rotating group often presents as a noticeable decrease in hydraulic system performance, such as slow boom or bucket movements. If ignored, internal leakage will increase, leading to further power loss and potential overheating of the hydraulic fluid. The ultimate consequence is the inability to perform work functions, resulting in extended equipment downtime.

Installation Tip

Carefully inspect the pump housing for any scoring or wear marks before installing the new rotating group. Ensure all internal components are properly lubricated with clean hydraulic oil before assembly to prevent initial damage.

Service Note

Clean the hydraulic system thoroughly and replace the hydraulic filter element when installing a new pump rotating group.
