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

Initial signs of a failing Body As-Piston include a noticeable decrease in hydraulic system performance and potential leaks around the cylinder. If left unaddressed, the problem can escalate to inconsistent operation and increased wear on other hydraulic components. Continued operation with a compromised piston body risks significant damage to the entire hydraulic system.

Installation Tip

Ensure the cylinder bore is thoroughly cleaned and free of any debris before installing the new piston body. Avoid overtightening the piston rod to the body, as this can damage the threads or the component itself.

Service Note

Inspect the cylinder bore for wear or damage and replace all associated seals when servicing the Body As-Piston.
