Frequently Asked Questions
Q: Is the GW 083970-035-HL compatible with all Crown electric pallet jacks?
A: No, the GW 083970-035-HL is designed specifically for Crown GPW Series electric pallet jacks. Before ordering, verify your jack model against the GPW series lineup. Cross-reference part numbers CR 083970 and CR 083970-035-HL-A confirm fitment. Always check your current wheel bearing bore at 30mm (1.181 inch) to ensure compatibility. Do not force-fit this wheel on other Crown series or competitor equipment.
Q: What is the difference between the GW 083970-035-HL and the Crown OEM equivalent CR 83970-A?
A: The GW 083970-035-HL and Crown OEM part CR 83970-A are functionally equivalent. Both feature a 3.25 inch diameter by 4.5 inch width polyurethane load wheel with 30mm bearing bore and 95A hardness rating. The GW version is a direct replacement aftermarket part offering the same performance and durability. Verify part number on invoice to confirm you are receiving the equivalent specification.
Q: Can I use the GW 083970-035-HL as a drive wheel or only as a load wheel?
A: This is a load wheel assembly, not a drive wheel. It is designed to support and distribute the pallet load. Do not install this wheel in drive wheel positions. Installing a load wheel in place of a drive wheel will result in inadequate traction, loss of control, and potential equipment failure. Always match wheel type to its designated position on your pallet jack.
Q: What should I do if the GW 083970-035-HL shows uneven wear or wobbling?
A: Check the 30mm bearing bore for damage or corrosion. Spin the wheel by hand to feel for grinding or resistance. If the bearing is damaged, the wheel cannot be repaired and must be replaced. If bearing feels smooth, the wobble may indicate a bent axle or loose mounting bolts. Tighten all fasteners first. If wobbling persists, measure the axle with a dial indicator. Replace the wheel assembly if bearing bore shows wear or cracks.
Q: What is the maximum load capacity and operating temperature range for the GW 083970-035-HL?
A: The GW 083970-035-HL is rated for the full load capacity of the Crown GPW Series pallet jack in which it is installed. Typical Crown GPW Series jacks range from 5000 to 6000 pounds. The polyurethane tread with 95A hardness rating is suitable for temperatures between 40 degrees Fahrenheit and 120 degrees Fahrenheit. Do not operate in cold storage below 40 degrees F as the material becomes brittle. Do not expose to direct heat sources above 120 degrees F as the polyurethane may soften or deform.
Q: How often should the GW 083970-035-HL be inspected or replaced?
A: Inspect the wheel assembly every 500 operating hours or at least quarterly, whichever comes first. Look for flat spots, cracks in the polyurethane, or visible damage to the steel core. Replace the wheel if you see loss of material, deep gouges, or if the bearing bore shows play or noise. Typical service life is 2 to 4 years with normal indoor warehouse use. High-volume outdoor or rough floor applications may require replacement within 12 to 18 months.
