Frequently Asked Questions
Q: What type of spring is SKU 40505?
A: This is a compression or torsion spring used in the descent control linkage of manual pallet jacks. It provides return force and resistance to maintain fork position and control lowering speed.
Q: Which manual pallet jack models use this spring?
A: SKU 40505 fits multiple Crown, Toyota, Raymond, and Yale manual jack models. Cross-reference your jack model and production year against our compatibility chart to confirm fitment.
Q: What are the material and spring rate specifications?
A: This spring is made from high-carbon alloy steel tempered for durability. The specific spring rate and dimensions are critical to descent control function. Verify exact specifications against the original part before ordering.
Q: What causes spring failure?
A: Springs fail due to metal fatigue from repeated compression cycles, corrosion in wet environments, overloading beyond design capacity, or loss of temper from excessive heat. A failed spring results in poor descent control or inability to hold fork position.
Q: How long does this spring last?
A: A well-maintained spring typically lasts 5 to 7 years in normal use. High-cycle environments, inadequate lubrication, or corrosive storage conditions reduce lifespan significantly. Replace when the jack loses control responsiveness or descent becomes difficult to manage.
Q: Can I substitute a different spring for this part?
A: No. Spring rate, material composition, and dimensions are engineered for specific descent control behavior and load handling. Using an incorrect spring compromises safety and control. Use only the exact OEM equivalent.
