Frequently Asked Questions

Q: What is the plunger spring and what is its function?
A: The plunger spring is a compression spring that provides return force on the piston assembly. It ensures the piston returns to its original position after each pump stroke and maintains proper pump geometry and fluid flow.

Q: Is plunger spring DA 2748-55-96 compatible with my Dayton equipment?
A: This plunger spring is designed for Dayton model 4YX96 pallet jacks. Confirm your equipment model matches before placing an order.

Q: What material and specifications does this plunger spring have?
A: The plunger spring is a coil compression spring manufactured from tempered steel with corrosion-resistant coating. It is engineered to precise load and deflection specifications to maintain consistent pump performance across the operating range.

Q: What are symptoms of a failing plunger spring?
A: A failing spring causes sluggish or incomplete piston return, requiring excessive force on the pump handle or creating a spongy pump action. You may also notice the load lowering on its own or difficulty maintaining a stable raised position.

Q: What is the expected service life of a plunger spring?
A: A well-maintained plunger spring typically lasts 5 to 7 years or 75,000 plus lift cycles. Springs may fail prematurely if exposed to overloading, rust from moisture exposure, or high-frequency cycling beyond design capacity.
