This piston body is a fundamental component of the hydraulic system, housing the piston and seals to generate and direct hydraulic pressure. It is manufactured with precise tolerances and robust materials to withstand high pressures and temperatures, unlike a worn body that might show signs of scoring or deformation. Operators may observe a loss of hydraulic function, slow or jerky cylinder movement, or external hydraulic fluid leaks if this piston body is compromised.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A compromised piston body may first manifest as a slight decrease in hydraulic system pressure or a sluggish response from the affected cylinder. Over time, this can progress to jerky or inconsistent cylinder movement, and external leaks of hydraulic fluid may become apparent around the cylinder rod seal. Continued operation risks significant loss of hydraulic power and potential damage to other system components.
Carefully inspect the cylinder bore for any scoring or damage before installing the new piston body; imperfections can quickly damage new seals. Ensure all seals are properly seated and lubricated before assembly.
Inspect the cylinder bore, piston seals, and rod seals for wear or damage when replacing the piston body.
