Frequently Asked Questions

Q: What function does spring SKU 903040001 serve in pallet jacks?
A: SKU 903040001 is a compression or return spring used in manual and electric pallet jack lift mechanisms. Springs provide restoring force to return the mast or lift platform to neutral position after lowering and support load cushioning. Spring function varies by equipment model and application.

Q: What equipment brands and models use this spring?
A: This spring is compatible with pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and Mitsubishi. Exact fitment depends on lift mechanism design and load class. Verify your equipment model number and serial range to confirm compatibility before ordering.

Q: What are the spring specifications including free length and load rating?
A: Spring specifications including free length, compressed length, wire diameter, and load rating are critical for proper fitment. Review your equipment manual or contact us with your model information to obtain exact specifications. Incorrect spring dimensions or ratings will result in improper lift mechanism operation.

Q: What indicates that this spring needs replacement?
A: Replace springs if the mast or lift platform does not return to neutral position smoothly, feels loose or spongy, shows visible cracks or permanent deformation, or if the equipment requires excessive force to operate. Springs lose tension gradually over time and should be replaced as a set for balanced operation.

Q: How long does this spring typically last in service?
A: Spring service life typically ranges from 3 to 5 years depending on cycle frequency, load consistency, and maintenance. Facilities with high-volume daily use may experience shorter intervals. Environmental factors such as temperature extremes and humidity also affect longevity.
