Frequently Asked Questions
Q: What is the OEM part number for GWK-7HBW23-LW-XL, and is it equivalent to part 664110?
A: The manufacturer part number is GWK-7HBW23-LW-XL. The OEM part number is 664110, which this kit replaces and supersedes the older GWK-7HBW23-LW standard model. This kit is also equivalent to part 310700-248-KIT. When ordering, use the exact SKU GWK-7HBW23-LW-XL to ensure you receive the 97A durometer wheels. Always verify the cross-references on your invoice to confirm the correct part shipped.
Q: Does GWK-7HBW23-LW-XL fit all Toyota 7HBW23 pallet jacks, or are there serial number restrictions?
A: GWK-7HBW23-LW-XL fits Toyota 7HBW23 electric pallet jacks without serial number restrictions. However, always verify the model number on your jack nameplate before installation to confirm it is a 7HBW23. Do not use on 7HBC30, 7HBE30, or other models, as fork geometry and axle spacing differ. If your jack is a different model, order the correct kit for your specific model to ensure proper fit and safety.
Q: What is the difference between the XL version (97A) and the standard LW version (95A)?
A: GWK-7HBW23-LW-XL uses 97A durometer polyurethane wheels, while the standard LW version uses 95A wheels. The 97A compound is significantly harder and more wear-resistant, lasting 20-30 percent longer on rough floors, metal debris, and high-cycle operations. The trade-off is that 97A wheels mark floors more visibly. Choose XL for warehouses and demanding environments; choose standard LW for retail or polished floor protection. Both fit the same 7HBW23 jack.
Q: What is included in the kit, and what are the installation requirements?
A: GWK-7HBW23-LW-XL includes two durable 97A polyurethane wheel assemblies, axles, sealed bearings, and fasteners. Installation is straightforward: push the old axle out of the fork carriage, align the new assembly, slide the axle through, and secure fasteners with a socket wrench. Torque fasteners to 35-40 foot-pounds. Test wheel rotation by hand to verify smooth operation. Do not apply additional grease to sealed bearings. Total installation time is 15-20 minutes per wheel.
Q: What are the bearing specifications, and how long do sealed bearings last in cold storage or metal debris environments?
A: GWK-7HBW23-LW-XL bearings are sealed-design bearings rated for continuous duty in demanding environments. Under normal warehouse conditions, expect 18-24 months of life. In cold storage or areas with metal debris, sealed bearing life reduces to 12-18 months because contamination and temperature stress compound bearing wear. Listen for grinding noise and feel for resistance when rotating the wheel by hand. Once bearings fail, replace the entire wheel assembly. Do not attempt to clean or repack sealed bearings.
Q: Can these wheels handle overloaded pallet jacks, and what is the safety limit?
A: GWK-7HBW23-LW-XL wheels are rated for the load capacity of the Toyota 7HBW23 jack, which is typically 3,000 pounds. Do not exceed the jack load rating. Overloading causes wheel compression, flat-spotting, bearing seal failure, and axle bending. The 97A durometer resists compression better than 95A wheels, but exceeding load limits will damage any wheel. Always verify your jack load rating and never intentionally overload. Wheel failure under overload can injure operators or damage cargo.
