Frequently Asked Questions
Q: What equipment does the VJ 55F128 spring fit?
A: The VJ 55F128 is an OEM replacement return spring for Valu-Jack manual pallet jacks equipped with the 5500-2 hydraulic unit. It also fits alternate models 55002 and 5500-2. Verify your hydraulic unit model number before ordering.
Q: What material is the VJ 55F128 spring manufactured from?
A: The VJ 55F128 is manufactured from high-tensile spring steel, engineered to withstand repeated compression and extension cycles in the hydraulic release assembly without permanent deformation or loss of spring force.
Q: What is the function of the VJ 55F128 return spring?
A: The return spring provides restoring force in the hydraulic release mechanism, returning the lift arm to the neutral position after each release cycle. It ensures consistent, repeatable operation of the manual pallet jack release control.
Q: How long does the VJ 55F128 spring typically last?
A: In normal industrial use, high-tensile spring steel springs maintain functional spring force for 5-10 years. Lifespan depends on cycle frequency and load conditions. Replace if the release lever feels sluggish, if spring force is visibly reduced, or if the spring is cracked or broken.
Q: What symptoms indicate the VJ 55F128 spring needs replacement?
A: Replace the spring if the release lever does not return quickly to neutral position, if the lever feels loose or spongy, if visible cracks or breaks appear in the spring, or if manual effort is required to reset the release mechanism.
