Q: What symptoms indicate the VJ 457 filler screw needs replacement?
A: Replace the filler screw if you notice hydraulic fluid leaking from the top of the reservoir, if the screw is stripped and will not tighten properly, or if the internal strainer is clogged or damaged.
Q: How does a damaged VJ 457 affect pallet jack performance?
A: A leaking or loose filler screw allows hydraulic fluid to escape and air to enter the system, reducing lifting power, creating noise in the pump, and risking contamination of the fluid.

A: Check the filler screw monthly for tightness and leaks. Replace it if it becomes damaged, stripped, or if the internal vent or strainer is worn. Under normal use, plan to replace every 3 to 4 years.
