This piston body is a core component of a hydraulic cylinder assembly, housing the piston and facilitating its movement within the cylinder bore. It is manufactured to precise dimensions and material strength to withstand high pressures and operational stresses. Failure symptoms can include hydraulic fluid leaks around the cylinder, a loss of lifting or actuating force, and erratic cylinder movement.

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.
The initial symptom of a failing piston body is often a gradual loss of hydraulic power or speed in the affected cylinder. This can progress to noticeable external leaks of hydraulic fluid from the cylinder assembly or internal bypassing, leading to sluggish or non-functional operation. If left unaddressed, a damaged piston body can cause significant wear to the cylinder bore and other internal components, potentially leading to complete hydraulic system failure.
Ensure the cylinder bore is meticulously cleaned and inspected for any imperfections before inserting the new piston body. Avoid using sharp tools to guide the piston body into the cylinder, as this can easily damage the sealing surfaces.
When replacing a piston body, it is standard practice to also replace the cylinder seals, wipers, and potentially the piston rings for a complete and reliable repair.
