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 a failing unloader kit include inconsistent hydraulic system response or a noticeable drop in operating pressure. If left unaddressed, the system may operate erratically, leading to inefficient performance and potential damage to hydraulic components. The worst-case scenario involves the inability to operate critical functions, causing significant operational disruption.

Installation Tip

Thoroughly flush the hydraulic system before installing the new unloader kit to remove any contaminants. Ensure all seals are properly seated and that the valve is installed in the correct orientation.

Service Note

Inspect the hydraulic fluid and filter for contamination when replacing the unloader kit.
