Frequently Asked Questions
Q: What equipment does the 00591-22710-81 spring fit?
A: This spring assembly is designed for manual pallet jack lift mechanisms. It fits a range of standard manual pallet jack models from manufacturers including Crown, Toyota, and Raymond. Verify your jack model and serial range before ordering to ensure compatibility.
Q: What is the function of this spring in a manual pallet jack?
A: This spring provides tension and load support for the lift arm mechanism on manual pallet jacks. It helps maintain proper pressure on the hydraulic pump system and assists in lowering the forks when the release valve is engaged. A worn or broken spring will cause sluggish lifting or uneven fork height.
Q: How do I know if this spring needs replacement?
A: Replace the spring if you notice the lift arm is hard to pump, the forks drop unevenly, or the jack feels less responsive during operation. Physical inspection may show cracks, permanent deformation, or rust on the spring surface. Spring replacement typically extends the operational life of your manual pallet jack by 3-5 years depending on usage intensity.
Q: What material is this spring made from?
A: This spring is manufactured from heat-treated alloy steel, which provides durability and corrosion resistance in indoor and light outdoor material handling applications. The spring is designed to withstand repeated compression and extension cycles typical of daily pallet jack operation without permanent set or failure.
Q: Is special training required to install this spring?
A: No special certification is required, but you should have basic mechanical knowledge and the proper tools. Ensure the jack is fully lowered and on a flat surface before removing the old spring. Wear work gloves during installation. If you are unfamiliar with the process, detailed installation instructions are available with the part, or you can contact our technical support team.
