Product Description
WanMax GWK-W55-LW load wheel replacement kit designed for Model W55 manual pallet jacks. Features dual ultra-polyurethane wheels rated at 70 Shore D durometer, measuring 2.75 x 3.75 inches diameter. Complete assembly includes factory-installed precision bearings, replacement axles, and mounting fasteners. Black polyurethane construction provides load-bearing capability for material handling applications.

Frequently Asked Questions
Q: Is GWK-W55-LW compatible with WanMax W55 pallet jacks made before 2020?
A: GWK-W55-LW is engineered for all WanMax W55 manual pallet jacks regardless of manufacture date, provided the jack has not been modified. The 2.75 x 3.75-inch Ultra-Poly wheel profile and chrome steel double-sealed bearing construction are standard across the W55 production run. Verify your jack nameplate reads W55 and check that the original axle bores match the kit specifications before ordering.
Q: What symptoms indicate that GWK-W55-LW load wheels need replacement?
A: Replace wheels when flat spots or cracks exceed 0.125 inches in depth or length; when the 70D durometer polyurethane feels soft or tacky to the touch (indicating chemical contamination or age hardening); when wheels emit a grinding sound during rotation (bearing seal failure); when visible debris is embedded in the tread and cannot be removed; or when sideways drift develops under load (bearing preload loss). A visual hardness test is to press a fingernail into the tread; if it leaves a permanent indentation, durometer has degraded beyond safe limits.
Q: Do I need to replace the axles when installing GWK-W55-LW wheels?
A: GWK-W55-LW kit includes replacement axles and fasteners. You do not need to reuse old axles. However, if your original axles are straight and not visibly damaged (no bending, scoring, or rust), you may reuse them if the kit bearings fit without excessive play. Inspect old axles for pitting or corrosion before deciding to reuse. When in doubt, use the new axles supplied in the kit to ensure bearing preload consistency.
Q: Can GWK-W55-LW wheels be used on outdoor concrete or only indoor floors?
A: The Ultra-Poly 70D compound is rated for both indoor and outdoor concrete. However, outdoor use accelerates wear due to UV exposure, temperature cycling, and abrasive aggregate surfaces. On rough outdoor concrete, expect wheel lifespan to reduce to 6-9 months versus 12-18 months on smooth indoor floors. After outdoor use, inspect wheels monthly for surface crazing (hairline cracks), which signals imminent failure.
Q: What is the proper installation torque for GWK-W55-LW fasteners?
A: The kit does not specify fastener torque values. Hand-tighten fasteners until snug, then apply an additional 0.25-turn with a wrench. Over-tightening can warp the wheel bore and crush bearings; under-tightening allows axial movement and premature bearing failure. After the first eight hours of operation, re-check fastener tightness. Repeat the check every 200 operating hours.
Q: How does the 70D durometer rating affect GWK-W55-LW performance?
A: 70D Shore durometer indicates medium-hardness polyurethane, a balance between grip and wear life. Softer compounds (60D-65D) provide better grip but wear faster; harder compounds (80D+) last longer but offer reduced traction on smooth floors. The 70D rating in GWK-W55-LW is optimized for standard warehouse concrete. If your floor is very smooth (polished), grip may feel loose; if very rough (exposed aggregate), wear will be accelerated.
