Frequently Asked Questions
Q: What pallet jack models does the DA 2748-4ZY77-001 fit?
A: This load roller assembly is designed for Dayton model 4ZJ77 pallet jacks. Do not attempt to fit this on 4ZJ76 or 4ZJ78 models, as dimensions differ.
Q: What material is the load roller and hub made from?
A: The roller is polyurethane and the hub is steel. The assembly includes sealed ball bearings for smooth, low-maintenance operation.
Q: Is this the same assembly as the DA 2748-4ZY76-001?
A: No. Both are standard poly load rollers, but the DA 2748-4ZY77-001 is sized specifically for Dayton 4ZJ77 models. Do not interchange with DA 2748-4zy76-001 (which fits 4ZJ76) or DA 2748-4ZY78-001 (which fits 4ZJ78).
Q: What is the expected lifespan for this load roller?
A: Under typical warehouse operations, expect 1 to 2 years of service before replacement. Heavier loads, rough floors, and continuous use will shorten the lifespan.
Q: Can I upgrade to the ultra poly version for my 4ZJ77?
A: Yes. For the Dayton 4ZJ77 model, you can upgrade from the DA 2748-4ZY77-001 (standard poly) to the DA 2748-4zy77-002 (ultra poly) for increased durability in high-cycle or challenging floor conditions.
Q: Are the bearings serviceable on this assembly?
A: The bearings are sealed and cannot be serviced. If the roller does not rotate freely or makes grinding sounds, replace the entire assembly.
