Frequently Asked Questions
Q: What is the material specification for the RL 4-00083 piston pusher?
A: The RL 4-00083 piston pusher is manufactured from alloy steel that has been hardened and finished with a protective oil film. This material composition resists deformation under repeated hydraulic actuation forces and provides corrosion protection.
Q: What is the function of the RL 4-00083 piston pusher?
A: The RL 4-00083 is a hardened steel linkage component that transfers actuation force to the hydraulic piston on Rol-Lift Series T and E manual pallet jack hydraulic units. It is engineered to withstand the repetitive force cycles of manual pump operation.
Q: Is the RL 4-00083 included in factory Rol-Lift repair kits?
A: The RL 4-00083 piston pusher is compatible with factory repair kits for Rol-Lift Series T and E manual pallet jacks and may be included as part of complete rebuild kits. Check your kit contents to confirm whether the piston pusher is pre-assembled.
Q: Which Rol-Lift pallet jack models require the RL 4-00083?
A: The RL 4-00083 piston pusher fits Rol-Lift Series T and E manual pallet jacks. Verify your equipment series and confirm compatibility with your specific hydraulic unit before ordering.
Q: When should the RL 4-00083 piston pusher be replaced?
A: Replace the RL 4-00083 when the piston fails to extend fully, the linkage makes clicking or clunking sounds during pump operation, or visual inspection reveals cracks or permanent deformation. Once damaged, the piston pusher cannot be repaired and must be replaced as a complete assembly.
