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

Symptoms of a failing unloader kit can include sluggish hydraulic response or a sudden loss of hydraulic pressure. If ignored, the system may operate at incorrect pressures, leading to overheating and potential damage to pumps and cylinders. Continued operation risks significant hydraulic system component failure.

Installation Tip

Thoroughly flush the hydraulic system to remove any debris before installing the new unloader kit, as contaminants can cause immediate failure. Ensure all O-rings and seals are properly lubricated and seated to prevent leaks.

Service Note

Inspect the hydraulic pump and cylinders for signs of wear or damage, and check hydraulic fluid levels and condition.
