Frequently Asked Questions
Q: What does the LF 20243 ram piston do in a pallet jack?
A: The LF 20243 is the main piston rod component in the hydraulic pump assembly. It transfers hydraulic pressure from the manual pump handle to the load-bearing cylinder, controlling lift height and load movement.
Q: What Lift-Rite models use the LF 20243 ram piston?
A: The LF 20243 is compatible with Lift-Rite model L-55 (alternate designations include L55 and L 55). Verify your jack serial number against the L55 range before ordering.
Q: What materials compose the LF 20243?
A: The LF 20243 ram piston is manufactured from hardened steel with precision machining to maintain hydraulic seal integrity. The piston rod diameter and stroke are precisely calibrated for L-55 hydraulic pressure specifications.
Q: When should the LF 20243 ram piston be replaced?
A: Replace the piston if the jack fails to hold load, descends slowly without pump operation, or if hydraulic fluid leaks from the pump area. These symptoms indicate piston seal degradation or rod scoring.
Q: Does the LF 20243 require accompanying seal kits?
A: Yes, the LF 20243 ram piston works with hydraulic seal kits. When replacing the piston rod, include a complete seal kit overhaul to restore full hydraulic performance and prevent internal leakage.
