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 symptoms of failure include sluggish or hesitant swing response, and unusual noises during rotation. If left unaddressed, the drive may lose power, fail to hold the upper structure, or suffer internal damage, leading to significant operational limitations. Continued use risks damage to the swing bearing and potential uncontrolled movement of the upper structure.

Installation Tip

Ensure the mounting surfaces on the machine and the drive are perfectly clean and free of debris before assembly. Avoid overtightening mounting bolts, as this can distort the housing and cause premature failure.

Service Note

Inspect the swing bearing and hydraulic system for leaks or contamination when replacing this drive group.
