GWK-W45Z-LW

Frequently Asked Questions

Q: Is the GWK-W45Z-LW a direct replacement for all W45Z production serial ranges?
A: The GWK-W45Z-LW is engineered as a direct replacement for Hyster W45Z series electric pallet jacks. Confirm your equipment model designation matches W45Z, W45ZHD, W40XL, or W40XT. Early production units may have different axle configurations or hub specifications. Verify the existing wheel assembly axle pin diameter and mounting hub bore dimension before ordering to ensure compatibility.

Q: What durometer rating is included and how does 95A compare to alternative wheel grades?
A: The GWK-W45Z-LW features 95A polyurethane wheel hardness, suitable for standard duty cycles of 4-6 hours daily. The 95A compound balances wear resistance with floor grip and vibration damping characteristics. For equipment operating continuous shifts or exceeding 6 hours daily, consider upgrading to 97A XL-grade wheels for extended service life. Standard 95A wheels typically last 12-15 months under normal duty before wear requires replacement.

Q: What components are included in this kit and what grade are the fasteners?
A: The kit includes two 3.25 x 4.50 inch polyurethane wheels, hardened steel axles, precision roller bearings, cadmium-plated steel fasteners, cotter pins, roll pins, and standard Zerk-type grease fittings. All fasteners meet factory equipment specifications and load rating requirements. Do not substitute aftermarket fasteners as they may not provide adequate load capacity. All components are matched to factory bearing specifications.

Q: How do I verify bearing condition and detect premature wear?
A: Manually spin wheels and listen for grinding or roughness indicating bearing damage. Excessive side-to-side play greater than 0.03 inches indicates worn bearings requiring replacement. Brown discoloration or rust on bearing races signals water ingress and seal failure. Wheels that lock suddenly or make noise during operation need immediate bearing inspection. Check bearing grease by removing the grease fitting and inspecting debris on the grease gun tip. Dark or black-colored grease indicates bearing wear particles.

Q: What grease type and lubrication interval are recommended?
A: Use NLGI Grade 2 multi-purpose lithium grease with SAE Grade equivalent to ISO VG 100. Lubricate grease fittings every 250 operating hours or monthly during normal warehouse duty. For harsh conditions with significant dust or moisture exposure, increase frequency to every 125 operating hours. Pump grease until fresh lubricant appears at bearing seals, then stop. Over-greasing forces contamination past seals. Purge and replace grease in fittings every 500 operating hours by purging old grease until clean lubricant emerges.
