Frequently Asked Questions
Q: Is GWK-W60Z-LW a direct replacement for older Hyster W60Z electric jacks?
A: GWK-W60Z-LW is a direct-fit replacement for all Hyster W60Z series walkie electric pallet jacks. The 3.25 x 6.5-inch Durarun 95A polyurethane wheel profile and mounting interface are consistent across the W60Z production line. No axle modification or frame drilling is required. Verify your jack nameplate matches W60Z before ordering; do not attempt to fit this kit to W50Z or W70Z models.
Q: How does the GWK-W60Z-LW wheel size differ from similar Hyster models?
A: GWK-W60Z-LW wheels measure 3.25 inches diameter by 6.5 inches width. Hyster W50Z wheels are narrower (4.50-inch width), and W70Z wheels are wider and taller (4.00-inch diameter). The W60Z geometry is engineered for mid-duty electric pallet jack applications with higher speed and faster load cycles than the W50Z. Width and diameter are not interchangeable between models; mismatched wheels cause uneven load distribution and binding on the mast carriage.
Q: Can GWK-W60Z-LW be used on manual W60Z pallet jacks or only electric models?
A: GWK-W60Z-LW is designed for Hyster W60Z electric (walkie) pallet jack platforms only. Hyster does not manufacture a manual W60Z model. If you operate a manual pallet jack with a similar footprint, confirm the nameplate designation; if it does not read W60Z, do not use this kit. Hyster manual jacks require different wheel profiles due to load dynamics and frame geometry.
Q: What diagnostic steps should I follow if GWK-W60Z-LW wheels squeal after installation?
A: Squealing typically indicates bearing seal contamination or dry bearings. First, rotate each wheel by hand; if movement is rough or jerky, the bearings need replacement. Check that the axles turn freely and that fasteners are not over-tightened, which crushes bearing races. If hand rotation is smooth but squealing persists, apply a light machine oil (ISO 32) to the bearing seals; do not over-grease, as excess lubricant attracts dirt. If squealing continues after 20 operating hours, replace the wheel assembly.
Q: What is the maintenance interval for GWK-W60Z-LW wheels on high-duty electric jacks?
A: For electric jacks operating at full duty (continuous use, multiple load cycles per hour), inspect GWK-W60Z-LW wheels every 100 operating hours. Check for flat spots, tread wear depth, and bearing noise. Lubrication fittings should be greased every 200 operating hours or when the jack is serviced. On standard-duty jacks (intermittent use, 4-8 hours per day), extend inspection to 250 hours. Worn wheels accelerate bearing wear; do not delay replacement beyond visible tread loss.
Q: Does GWK-W60Z-LW include lubrication fittings or sealed bearings?
A: GWK-W60Z-LW wheels include sealed ball bearings that are pre-lubricated at the factory. The kit also includes axle lubrication fittings for periodic greasing of the axle shafts, not the wheel bearings themselves. Grease the axle fittings per maintenance schedule; sealed wheel bearings do not have grease fittings. Do not attempt to force grease into sealed bearings, as this can rupture seals and contaminate bearing races.
