Frequently Asked Questions
Q: What is a tappet and what does it do in a manual pallet jack?
A: A tappet is an internal valve component in manual pallet jack hydraulic units. It transfers force from the pump cam to the hydraulic pump valve, controlling hydraulic fluid flow during pump actuation. This part is essential for proper lift cylinder operation and load control.
Q: Which manual pallet jack brands use the 40632 tappet?
A: Part 40632 is compatible with Crown manual pallet jacks. Verify your jack model and serial number against the compatibility documentation to confirm fit before ordering.
Q: What material is the 40632 tappet made from?
A: The 40632 tappet is a precision-machined metal component engineered to withstand continuous hydraulic pressure cycling during manual operation without deformation or wear.
Q: What are the symptoms of a failing tappet in a pallet jack?
A: Signs of tappet failure include difficulty engaging the pump, inconsistent or weak lift pressure, jerky lifting motion, or the load drifting down faster than normal. If these symptoms appear, the tappet may require replacement.
Q: Can the 40632 tappet be removed and replaced without replacing the entire pump?
A: The tappet is an internal component of the hydraulic pump unit. Removal and replacement typically requires disassembly of the pump assembly. Consult your equipment documentation for specific guidance.
