Clark hydraulic lift piston for CJ55 pallet jack

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 manual pallet jack applications. It plays a critical role in the hydraulic pump assembly by generating 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: The CL 1808152 is typically manufactured from ductile iron or steel alloy to provide the strength needed to withstand repeated reciprocating motion and hydraulic pressure cycles.

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 part number CL 1808152 for the CJ55 hydraulic unit. No cross-reference or equivalent parts are available for this application.
