Frequently Asked Questions
Q: What are the thread size and length specifications for the HJ 125 adjusting screw?
A: The HJ 125 is a precision adjusting screw used in manual pallet jack pump assemblies. Exact thread specifications (diameter, pitch, and length) vary by application. Contact us with your equipment model and serial number to confirm the exact thread size and length required for your pallet jack, as substituting incorrect specifications can affect pump performance.
Q: Which manual pallet jack models use the HJ 125 adjusting screw?
A: The HJ 125 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other OEM manufacturers that use similar pump adjustment mechanisms. Compatibility depends on the specific model and vintage of your equipment. Verify your equipment model and serial range before ordering to ensure fitment.
Q: What material is the HJ 125 adjusting screw manufactured from?
A: The HJ 125 is manufactured from steel with corrosion-resistant finish suitable for hydraulic pump environments. Steel construction provides the precision fit and durability needed for repeated pump adjustment cycles without stripping or degradation of the threads.
Q: Can the HJ 125 be used as a cross-reference for other OEM adjusting screws?
A: The HJ 125 can serve as a cross-reference for equivalent OEM adjusting screws in compatible manual pallet jack models. However, exact cross-referencing requires matching the thread specification, length, and hex size to your equipment OEM part number. Contact us with your equipment documentation for accurate cross-reference verification.
Q: What is the purpose of this adjusting screw in the pallet jack pump assembly?
A: The HJ 125 is used to calibrate and adjust the pump pressure relief setting and flow characteristics in manual pallet jack hydraulic systems. Proper adjustment ensures correct lifting pressure, smooth operation, and protection against over-pressurization. Incorrect adjustment can result in weak lifting, slow operation, or pressure relief activation.
