Frequently Asked Questions
Q: What is the 00591-05387-81 bearing assembly and which manual pallet jacks use it?
A: The 00591-05387-81 is a bearing assembly for manual pallet jack pivot locations, installed on equipment from Toyota, Crown, Yale, and Raymond models. This assembly handles radial loads from the pump handle and hydraulic control linkage. Verify your pallet jack model and serial number before ordering to confirm compatibility.
Q: What materials and design features does the 00591-05387-81 have?
A: The 00591-05387-81 features hardened steel raceways, a steel roller or ball retainer cage, and factory-installed high-performance grease. The assembly is sealed or partially sealed to exclude dirt and moisture from entering the bearing during field operation. Do not disassemble the bearing.
Q: How do I remove and replace the 00591-05387-81 bearing assembly?
A: Remove the pivot bolt holding the bearing in place, then slide the assembly out of the frame bore. Clean the bore with a dry cloth to remove rust and debris, then slide the new 00591-05387-81 bearing into position and reinstall the bolt. Do not apply lubricant; the bearing is pre-greased and sealed.
Q: What symptoms indicate the 00591-05387-81 bearing needs replacement?
A: Replace the bearing if you notice grinding or squealing noise during pump operation, loose or play in the pivot connection, difficulty moving the control handle, or visible damage to the bore or bolt hole. Do not attempt to re-grease or repair; replacement is the only solution.
Q: What is the typical lifespan of the 00591-05387-81 bearing assembly?
A: Service life typically ranges from 2 to 4 years under normal warehouse conditions. Heavy use, exposure to moisture or salt air, or operation without regular maintenance may reduce lifespan to 1 to 2 years. Replace proactively if your pallet jack is approaching 3 years of age and operates under high-cycle conditions.
