Frequently Asked Questions
Q: What does the XL designation mean on GWK-B80ZHD-LW-XL?
A: XL indicates the wheels feature a 97A durometer rating, the highest standard polyurethane hardness. This provides maximum wear resistance, extending wheel life significantly in demanding applications. GWK-B80ZHD-LW-XL is ideal for facilities running 24/7 operations, high-traffic warehouses, or environments with rough or uneven flooring. The trade-off is slightly reduced traction and increased noise compared to the standard 95A model. Choose XL if durability is your priority over comfort.
Q: Can I interchange GWK-B80ZHD-LW-XL and GWK-B80ZHD-LW wheels on the same truck?
A: Not recommended. While both kits fit the B80ZHD frame, mixing durometer ratings will cause uneven load distribution and unstable handling. Install either all 95A wheels or all 97A wheels, never a combination. Mismatched wheels increase stress on the jack frame and can damage the hydraulic system. If you are changing from standard to XL wheels, replace all load wheels and steer wheels as a complete set.
Q: How do I diagnose if GWK-B80ZHD-LW-XL wheels need replacement?
A: Inspect wheels every 50 operating hours or monthly, whichever comes first. Replace if you observe flat spots on the wheel surface, visible cracks or chunks missing from the polyurethane, uneven wear patterns suggesting bent axles, wheels that no longer track straight, or a diameter difference of more than 1/8 inch between wheels. Also replace if wheels no longer grip the floor and the jack slides or skids during normal operation. Do not attempt to repair polyurethane wheels; replacement is the only safe option.
Q: What is the installation procedure for GWK-B80ZHD-LW-XL?
A: Lower the jack completely and secure it on wooden blocks or a work stand to prevent accidental lowering. Unbolt the fasteners on the axle ends using appropriate wrenches. Slide off old wheels and bearings. Clean the axles with a dry cloth. Insert new axles through the frame, install new bearing races on each side, then install wheels. Reinsert fasteners and tighten firmly. Do not use air tools which can overtighten and crack axles. Spin each wheel by hand to confirm smooth rotation before operating the truck.
Q: Will 97A durometer wheels mark floors?
A: GWK-B80ZHD-LW-XL wheels are formulated as non-marking, so they will not leave black marks on tile, polished concrete, or painted floors even at 97A durometer. However, on extremely smooth or waxed surfaces, any polyurethane wheel can cause temporary track marks. Wipe the wheels with a damp cloth before operating on pristine floors. If marks appear, they are typically surface-level deposits that can be wiped away and do not represent permanent floor damage.
Q: What bearing type is used in GWK-B80ZHD-LW-XL?
A: GWK-B80ZHD-LW-XL includes hardened steel bearing races designed for heavy-duty service. These are sealed or shielded to keep debris out and reduce maintenance. Do not apply grease or oil to the bearings as this attracts dirt and can cause binding. If a bearing becomes noisy or rough, inspect the axle for bending. Replace bent axles immediately as they cause bearing damage and uneven wheel wear. Bearing replacement without axle replacement is not recommended as damaged axles will destroy new bearings.
