Frequently Asked Questions
Q: Is GWK-W45XT-LW-XL compatible with Crown Equipment pallet jacks?
A: GWK-W45XT-LW-XL is engineered for Hyster W45XT equipment. Crown Equipment equivalent reference number is 310700-203-KIT for similar-class applications. Cross-compatibility depends on axle diameter, bearing bore, and mounting hub specifications. Do not assume direct fit to Crown units without verifying hub bore diameter and axle pin size match the Crown specification.
Q: What is the durometer rating and when should I choose 97A over 95A polyurethane?
A: GWK-W45XT-LW-XL features 97A Shore hardness polyurethane, designed for heavy-duty service exceeding 4-6 hours daily operation. The 97A rating provides extended service life and lower wear rate compared to 95A wheels. Choose 97A if equipment runs continuous shifts or on rough concrete. Use 95A for standard duty and smoother warehouse floors where vibration isolation matters more than wear resistance.
Q: What are the wheel dimensions and weight capacity limits?
A: Wheel diameter is 3.25 inches with 4.5 inches face width. The XL service grade designation indicates heavy-duty load rating exceeding standard W45XT specifications. Actual load capacity depends on jack base model and load distribution. Verify your equipment nameplate for maximum lift capacity before operation. Do not exceed manufacturer rated load even with upgraded wheels.
Q: How do I diagnose worn wheels and what is typical service life?
A: Inspect wheels for flat spots, uneven wear, or reduced grip. Worn wheels exhibit visible tread loss and may cause steering drift or noise during operation. Typical service life is 12-18 months under heavy duty usage with proper maintenance. Check grease fitting torque and bearing play monthly. If wheels develop cracks, chunking, or permanent flat spots, replacement is required. Do not attempt to resurface polyurethane wheels.
Q: Are grease fittings standard Zerk type and what maintenance schedule applies?
A: Yes, kit includes standard Zerk grease fittings on sealed bearing assemblies. Lubricate with NLGI Grade 2 multi-purpose grease every 250 operating hours or monthly, whichever comes first. Heavy-duty operation (XL grade) requires more frequent inspection. Do not over-grease as excess lubricant forces bearing seals outward and attracts contamination. Wipe excess grease from hub areas after each lubrication cycle.
Q: What tools and safety precautions are required for wheel kit installation?
A: Installation requires socket set, bearing puller, and cotter pin pliers. Raise jack to full height on level surface and fully lower load forks before starting work. Lock the jack using emergency lowering valve if equipped. Remove cotter pins and axle bolts, then use bearing puller to extract old assembly. Press new wheels onto hardened steel axles using proper bearing press tool. Do not hammer wheels onto axles. Reinstall fasteners and verify wheel spin freely with no binding before operating equipment.
