CL 1808152

Frequently Asked Questions

Q: What is the CL 1808152 and what role does it play in a manual pallet jack?
A: The CL 1808152 is a hydraulic lift piston for Clark CJ55 manual pallet jacks. It is a critical component of the hydraulic pump assembly that moves within the pump cylinder to generate pressure and volume flow needed to extend the lifting forks and raise loads.

Q: Which Clark models use the CL 1808152?
A: The CL 1808152 is specifically designed for the Clark CJ55 manual pallet jack hydraulic unit. Verify your equipment model and serial range against Clark documentation to confirm compatibility before ordering.

Q: What material is the CL 1808152 manufactured from?
A: Clark lift pistons for manual pallet jacks are typically manufactured from ductile iron or steel alloy to provide the strength needed to withstand repeated reciprocating motion and hydraulic pressure cycles. Material specifications are available in the Clark CJ55 technical documentation.

Q: How do I know if the CL 1808152 needs replacement?
A: Replace the piston if the jack loses lift pressure, leaks hydraulic fluid from the pump body, or if the handle becomes extremely difficult or impossible to pump despite seal replacement. A worn piston will not seal effectively against the pump bore and will cause internal bypass.

Q: Is the CL 1808152 a wear part that needs periodic replacement?
A: The piston itself is durable and does not normally wear out unless contamination or seal failure allows metal-to-metal contact. In most cases, you replace seals and wipers before the piston. However, if damage occurs or the piston surface becomes scored, replacement is necessary.

Q: Are there equivalent part numbers for the CL 1808152?
A: Use only the Clark OEM part number CL 1808152 for the CJ55 hydraulic unit. No cross-reference or equivalent parts are available for this application.
