PISTON (JLG JL91514152)

A worn piston can compromise the sealing integrity within a cylinder assembly. The piston is a reciprocating component that transfers force from expanding gas or fluid pressure to a connecting rod. When the piston's sealing surfaces degrade, internal leakage may reduce the system's ability to hold pressure or maintain consistent motion. This aftermarket replacement part references JLG catalog number JL91514152. The part is listed as a piston, a type-level component that moves linearly within a bore to convert pressure into mechanical work. A common failure consequence is loss of force transmission, leading to sluggish or incomplete movement. Verify the serial number or application, then call (562) 693-7748.
