Frequently Asked Questions
Q: What is the difference between GWK-SMX45-LW-XL and the standard GWK-SMX45-LW kit?
A: GWK-SMX45-LW-XL and GWK-SMX45-LW are interchangeable direct replacements for BT Prime Mover SMX45 jacks. Both include dual 97A durometer polyurethane wheels, sealed precision bearings, and heat-treated steel axles. The XL designation indicates extended-duty specification; XL kits are recommended for trucks operating over 4-6 hours daily. For light to moderate duty, either kit works. Verify your expected duty cycle before ordering.
Q: Can I use GWK-SMX45-LW-XL wheels if my truck is an older BT Prime Mover model?
A: GWK-SMX45-LW-XL is designed specifically for BT Prime Mover SMX45 and SMX 45 models. Before installation, verify your truck nameplate matches one of these models. If your truck is older (pre-2010), check the wheel axle diameter and bearing housing diameter against the kit specifications. If unsure, contact BT Prime Mover service or compare part numbers to ensure 100 percent fit. Installing incompatible wheels can damage the truck frame.
Q: What maintenance is required after installing the GWK-SMX45-LW-XL kit?
A: After installation, operate the truck 5-10 minutes at low speed to seat the wheels and bearings, then check that all fasteners remain tight. Recheck after 8 hours of operation. Every 40 operating hours, clean debris from around bearing seals and inspect tread for damage. Do not over-lubricate sealed bearings; they are packed for life. If you hear grinding noise within 20 hours of installation, remove wheels and verify bearing installation seats are flush with the wheel hub.
Q: Are replacement axles and fasteners included in the GWK-SMX45-LW-XL kit?
A: Yes, GWK-SMX45-LW-XL includes heat-treated steel axles and all mounting fasteners for direct replacement. You do not need to purchase additional components. If your existing axles are bent or damaged, do not reuse them; the kit provides new axles. Fasteners are Grade 8 or equivalent. Do not substitute with lower-grade fasteners.
Q: What floor conditions will affect the lifespan of the GWK-SMX45-LW-XL wheels?
A: Polished concrete and smooth warehouse floors maximize wheel lifespan (24-36 months). Rough, uneven, or debris-strewn floors reduce life to 12-18 months. Extreme temperatures below 40 degrees F will stiffen the polyurethane, reducing traction and increasing wear. Hot floors above 110 degrees F can soften the tread prematurely. Clean floors daily to prevent buildup of grit that accelerates wear.
