Frequently Asked Questions
Q: Is GWK-SMX45-LW compatible with GWK-SMX45-LW-XL, or do I need a different kit?
A: GWK-SMX45-LW and GWK-SMX45-LW-XL are cross-reference equivalents for BT Prime Mover SMX45 electric pallet jacks. Both fit the same application and use identical 97A polyurethane treads with sealed ball bearings. Choose either kit; they are direct replacements. Always verify your truck model (SMX45 or SMX 45) on the nameplate before ordering.
Q: What symptoms indicate the load wheels on my BT Prime Mover SMX45 need replacement?
A: Replace wheels when you observe flat spotting or visible wear patterns on the tread, reduced traction causing slippage on smooth floors, audible grinding or squealing from the bearing assembly, or visible cracks in the polyurethane tread. If the jack is over 2 years old in continuous duty (4-6 hours daily), inspect wheels quarterly. Worn wheels reduce load capacity and increase strain on the truck frame.
Q: How do I install the GWK-SMX45-LW wheel kit, and what tools do I need?
A: You need a socket set (metric or SAE depending on your truck generation), a rubber mallet, and a wheel bearing puller if bearings are pressed. First, lift the truck on blocks and remove the cotter pins and axle nuts. Pull the old wheel assembly off the axle shaft. Install new wheels by sliding them onto the axle, ensuring bearings seat fully, then torque nuts to the specification on your truck manual (typically 35-50 ft-lb). Install new cotter pins. Test wheel spin before operating. Do not operate the truck until wheels rotate freely.
Q: What is the load capacity rating for the GWK-SMX45-LW wheels?
A: GWK-SMX45-LW wheels are rated for the full capacity of the BT Prime Mover SMX45 truck, typically 4500-5000 lbs at a 24-inch load center, depending on your specific truck serial range. The 97A durometer polyurethane provides durable load support in continuous material handling environments. Exceeding rated load will void warranty and shorten wheel life. Check your truck nameplate for exact capacity.
Q: How long do these polyurethane load wheels typically last in continuous operation?
A: In continuous duty cycles of 4-6 hours daily, expect 18-36 months of service life for GWK-SMX45-LW wheels. Lifespan depends on floor surface (concrete extends life vs. rough warehouse floors), load distribution, and operator technique. Smooth floors and balanced loads extend wheel life. Inspect wheels every 500 operating hours and clean debris from bearing seals every 250 hours to maximize service life.
