Product Description
13/16 compression spring
Frequently Asked Questions
Q: What equipment uses the 13/16 compression spring SKU 00591-43271-81?
A: This 13/16 inch compression spring is used in forklift and pallet jack lift mechanisms to support mast return and load leveling. It is compatible with Toyota, Crown, Raymond, Hyster, and Linde equipment. Confirm the spring constant (force rating) matches your equipment specification before ordering.
Q: What is the force rating and compressed length of this compression spring?
A: The exact force rating (pounds per inch) and free length depend on your equipment model. The 13/16 designation refers to the outer diameter. Measure your current spring or consult your equipment manual to confirm the correct SKU, as different models require different spring rates.
Q: How long do compression springs last in material handling equipment?
A: A properly functioning compression spring lasts 5 to 10 years, depending on load cycles and maintenance. Springs fail when they lose tension, causing slow mast return, uneven lifting, or hydraulic pressure buildup. Replace springs in pairs to maintain balanced operation.
Q: What are the signs that this compression spring needs replacement?
A: Signs include slow or delayed mast return, uneven mast height when lowered, reduced lift speed, or visible rust and corrosion on the spring surface. A failed spring forces the hydraulic system to work harder, increasing wear on pumps and cylinders.
