🔌 Function

Converts fluid pressure into linear force to move the assembly it sits in, sealing against its bore as it travels.

⚠️ Common Signs of Failure

• Movement slow, weak or sinking back under load
• Fluid weeping past the piston or from the assembly
• Bore or piston skirt scored or scuffed
• Seals hardened, swollen or nicked on strip-down
• Rust staining showing water has entered the bore

🛠️ Service Notes

• Renew the seals and check the bore for scoring at the same time, since a scored bore will cut new seals
• Keep everything clean on reassembly, as grit is the usual cause of a repeat failure
