PISTON BALL
Frequently Asked Questions
Q: What is the IN 403958 piston ball component?
A: The IN 403958 is a piston ball component used in hydraulic pump assemblies of manual pallet jacks. Piston balls are precision spheres that work within the pump to create pressure and move hydraulic fluid through the system.
Q: What material is the IN 403958 piston ball made from?
A: Piston balls are typically manufactured from hardened steel to withstand repeated pressure cycles and maintain tight tolerances. Steel offers superior durability and resistance to deformation in high-pressure hydraulic pump environments.
Q: How can I tell if the IN 403958 piston ball is worn or damaged?
A: Worn piston balls cause reduced pump efficiency, difficulty engaging the lift mechanism, weak lift pressure, or grinding sounds from the pump. If your pallet jack requires excessive pump strokes to lift, the piston ball may be damaged.
Q: Which pallet jack brands use the IN 403958 piston ball?
A: The IN 403958 piston ball is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other standard OEM manufacturers. Confirm your pump assembly type and size before ordering.
