Frequently Asked Questions
Q: What pallet jack models does GWK-D40-LW fit?
A: GWK-D40-LW is designed exclusively for Big Joe D40 electric pallet jacks. The D40 is a powered lift model, not manual. This kit will not fit Big Joe manual models (L-series) or other manufacturers. Verify your jack has a D40 label on the pump assembly or title plate before ordering.
Q: What wheel material does GWK-D40-LW use?
A: GWK-D40-LW wheels are 95A polyurethane. For 97A polyurethane wheels, order GWK-D40-LW-XL instead.
Q: Can I use GWK-D40-LW wheels as a direct drop-in replacement without modifications?
A: Yes. GWK-D40-LW is engineered as a direct replacement for Big Joe D40 factory wheels. The kit includes pre-assembled wheel and bearing units that slide onto existing D40 axles. No drilling, welding, or frame modifications are required. Installation requires only basic hand tools and approximately 45 minutes per wheel assembly.
Q: How do I diagnose wheel failure on a Big Joe D40 electric jack?
A: Warning signs include: reduced speed or increased motor load during operation, steering difficulty or pulling to one side, audible grinding or squealing, or visible flat spots and chunks missing from wheel surface. Test by lifting the jack slightly and manually rotating wheels. Wheels should spin freely with minimal resistance. If they do not, or if motor current increases noticeably, wheels require replacement.
Q: What is the load capacity of GWK-D40-LW wheels?
A: GWK-D40-LW wheels support the full rated capacity of Big Joe D40 electric jacks, which is typically 3,300-4,000 lbs depending on your specific model year. Do not exceed the nameplate rating. Overloading accelerates wheel wear and can cause bearing failure within weeks. Always verify your jack model to confirm exact load specification.
Q: How long do GWK-D40-LW wheels last in typical warehouse operation?
A: Expected wheel lifespan depends on daily use and floor conditions. Lifespan is reduced by 30-50% if the jack operates on abrasive surfaces or if wheels are not properly maintained. Keep bearing axles lubricated annually.
