Lw Assy 4 x 1-7/8 for Prime Mover Electric Lift Truck

Frequently Asked Questions

Q: What does PR 309882-X01-A represent and what is included in this assembly?
A: The PR 309882-X01-A is a load wheel assembly with a 4 inch diameter and 1-7/8 inch width. The A-suffix designation indicates this is a complete assembled wheel unit, typically including the polyurethane tire, wheel hub, and bearing pre-installed. Verify your specific equipment requirements to confirm if you need the wheel alone or the full assembly.

Q: Is the PR 309882-X01-A a complete ready-to-mount unit or a wheel-only item?
A: The PR 309882-X01-A is a complete load wheel assembly. The A-suffix indicates it comes with the wheel, hub, and bearing already assembled. This differs from wheel-only SKUs. Confirm your axle bore diameter and spindle length match before ordering to ensure proper fitment on your equipment.

Q: What polyurethane compound and durometer does the PR 309882-X01-A use?
A: The PR 309882-X01-A uses a standard 95A durometer polyurethane compound, delivering moderate hardness and reliable floor grip for typical warehouse operations. This compound balances load capacity against traction and maintains consistent performance in room-temperature environments across concrete and sealed flooring.

Q: Which electric pallet jack models fit the PR 309882-X01-A assembly?
A: The PR 309882-X01-A is compatible with electric lift trucks from BT Prime Mover, Raymond, Crown, Toyota, Yale, and Hyster that use 4 x 1-7/8 load wheel assemblies. Check your equipment documentation or measure the existing wheel assembly to verify spindle length, bore diameter, and wheel pocket depth match this assembly.

Q: How often should the PR 309882-X01-A assembly be replaced?
A: Under normal warehouse use, expect 12-20 months of service life before wheel replacement becomes necessary. The bearing longevity depends on lubrication maintenance and load consistency. Replace the entire assembly when wheel diameter drops below 3.75 inches or visible wear patterns, flat spots, or bearing noise develop.

Q: What maintenance does the PR 309882-X01-A bearing assembly require?
A: Most modern load wheel bearings are sealed units requiring minimal maintenance. Check for smooth rotation and listen for bearing noise during equipment operation. If bearing noise develops, the assembly should be replaced. Do not attempt to repack or service sealed bearings; replace the complete assembly.
