SEAL - CYLINDER PISTON (Clark CL1736247)

A damaged cylinder piston seal can allow pressurized fluid to bypass the piston, reducing force output and causing erratic movement. This aftermarket replacement part references Clark as the OE maker and cross-references part number CL1736247. The seal type creates a dynamic barrier between the piston and cylinder wall, preventing fluid leakage during reciprocating motion. A common failure consequence is internal leakage that leads to slow or incomplete cylinder extension under load. During a rebuild, technicians often find a worn seal that has hardened or developed cracks from thermal cycling. Verify the serial number or application, then call (562) 693-7748.
