Frequently Asked Questions
Q: What is the difference between GWK-W55-CK and GWK-W55-LW load wheel kits?
A: GWK-W55-CK is a complete wheel system replacement kit that includes dual Ultra-Poly 70D load wheels (2.75 x 3.75 inches) and dual steer wheels (7 x 2 inches) with integrated bearings, axles, and fasteners. GWK-W55-LW includes load wheels only. Use GWK-W55-CK when both load and steer wheels require replacement, or GWK-W55-LW when only the main load-bearing wheels are worn.
Q: Does GWK-W55-CK work on manual pallet jacks other than WanMax W55?
A: No. GWK-W55-CK is designed for WanMax W55 manual pallet jacks only. The 2.75 x 3.75-inch load wheel dimensions and 7 x 2-inch steer wheel profile are specific to the W55 geometry and axle spacing. Cross-fitting to other brands or models will result in misalignment, poor handling, and accelerated bearing failure.
Q: What maintenance does the GWK-W55-CK kit require after installation?
A: The GWK-W55-CK kit ships with pre-installed precision bearings sealed against contamination. No ongoing greasing is required. Inspect wheels monthly for cracks, flat spots, or embedded debris. Wipe the polyurethane tread after use if exposed to oil, water, or dirt. Check that axles turn freely by hand rotation; if friction increases, the bearings may be contaminated and the wheel assembly should be replaced.
Q: Can I install GWK-W55-CK wheels myself or do I need a technician?
A: GWK-W55-CK is designed for field installation without special tools. Remove existing fasteners holding the old wheel assemblies, slide new axles into position, and secure with supplied fasteners. Tighten fasteners in a cross pattern to ensure even seating. Total installation time is 20-30 minutes per wheel pair. No alignment adjustment is required on manual jacks; the kit bolts directly in place.
Q: What is the expected lifespan of the Ultra-Poly 70D wheels in the GWK-W55-CK kit?
A: Under normal warehouse conditions (smooth concrete floors, loads within nameplate capacity), the Ultra-Poly 70D load wheels last 12-18 months with daily use. Steer wheels typically outlast load wheels by 30-50 percent because they carry less load. Lifespan shortens significantly on rough floors, outdoor concrete, or when jacks are overloaded. Inspect wheels at six-month intervals for tread wear depth and durometer hardening.
Q: Are the fasteners in GWK-W55-CK stainless steel or carbon steel?
A: GWK-W55-CK fasteners are high-strength carbon steel with plating for corrosion resistance. They are not stainless steel. If your warehouse uses salt spray, caustics, or washdown environments, consider applying a thin coat of waterproof grease to fasteners after installation to extend life. Check fastener tightness every three months in wet environments; corrosion can reduce preload.
