Frequently Asked Questions
Q: What manual pallet jack models use the 00591-30373-81 bearing assembly?
A: This bearing assembly fits standard manual pallet jacks from Crown, Toyota, Raymond, and Yale equipment. Check your serial number and hydraulic pump configuration to confirm compatibility before ordering, as bearing specifications vary by lift height and load wheel diameter.
Q: How do I know if the 00591-30373-81 bearing assembly needs replacement?
A: Replace this bearing assembly if you hear grinding or squealing noises during operation, notice resistance when raising the mast, or feel grinding sensation through the pump handle. Visual inspection should also reveal excessive play or discoloration at the bearing seat.
Q: What is the installation procedure for the 00591-30373-81 bearing assembly?
A: Lower the mast fully before installation. Remove the pump rod assembly and old bearing. Press the new bearing onto the pump shaft using a press tool, ensuring it seats fully against the shoulder. Verify bearing spins freely by hand before reassembling the pump. Do not use a hammer or impact tool for installation.
Q: What material is the 00591-30373-81 bearing assembly made from?
A: This bearing assembly uses hardened steel races and stainless steel balls designed for pump duty service. The bearing cage is made from bronze or composite material to minimize wear and provide long service life in a hydraulic environment.
Q: How often should I maintain or replace the 00591-30373-81 bearing assembly?
A: Most bearing assemblies last 3 to 5 years with normal fleet duty and regular hydraulic fluid changes. If you operate in dusty or wet environments, inspect bearings annually. Replace if binding develops or seal integrity fails. Extend service life by keeping the pump rod clean and maintaining proper hydraulic fluid viscosity.
