GW 528-A

Frequently Asked Questions

Q: What are the cross-reference part numbers for the GW 528-A load wheel?
A: The GW 528-A is equivalent to GP 528-A, GW528-A, GP 528A, GW528A, and 528A. All these part numbers reference the same assembly with a 3.250 inch diameter, 6.380 inch width, and 25mm bearing ID. When ordering, verify your equipment model because this wheel size is specific to certain electric lift truck designs. Check your current wheel marking to confirm compatibility before purchase.

Q: Is the GW 528-A wheel compatible with my electric pallet truck?
A: The GW 528-A is designed for electric lift trucks, not electric pallet trucks. Do not install this assembly on electric pallet trucks or walkies, as the 6.380 inch width is significantly wider than standard pallet truck wheels. Verify your equipment type and mounting dimensions before purchase. Using an incompatible wheel size will prevent proper operation and may cause damage to the truck frame or steering assembly.

Q: How do I know if the GW 528-A wheel bearing needs replacement?
A: Symptoms of bearing failure include grinding or squeaking sounds during operation, excessive wobble when spinning the wheel by hand, or difficulty rotating the wheel freely. To test, lift the truck and spin each wheel manually. A good bearing rotates smoothly with minimal resistance and stops gradually. If the wheel locks up, does not spin, or produces noise, the assembly requires replacement. Do not operate the truck with a failed bearing as this creates a safety hazard.

Q: What is the load capacity and operating temperature range for the GW 528-A?
A: The GW 528-A is rated for the standard electric lift truck load capacity specified by your equipment manufacturer, typically 2000 to 3000 pounds per wheel assembly depending on truck model. The Durarun 95A polyurethane tread operates reliably between minus 20 degrees Fahrenheit and plus 160 degrees Fahrenheit. Do not exceed these temperature limits or use in extreme conditions, as material degradation may reduce traction and load-holding capability. Verify your truck rating before operation.

Q: How often does the GW 528-A wheel require maintenance?
A: Inspect the GW 528-A wheel monthly for tread wear, flat spots, or damage. Clean debris and dust from the wheel and bearing surfaces to prevent accelerated wear. The polyurethane tread typically lasts 2 to 4 years depending on floor type and usage intensity. Rough or slippery concrete shortens life. When tread depth reduces by half or wear patterns become uneven, plan wheel replacement. Lubricate the bearing if your truck design permits access, using only light machine oil. Never use grease, which attracts dirt and causes premature failure.

Q: What tools and steps are required to install the GW 528-A wheel assembly?
A: Installation requires a socket set, wheel hub removal tool (if applicable), and an arbor press for pressing the bearing onto the shaft. First, raise the truck and secure it on jack stands. Remove the fastener or snap ring holding the old wheel. Press off the old assembly and inspect the axle shaft for damage. Press the new GW 528-A assembly onto the shaft, ensuring the bearing is fully seated. Reinstall the fastener or snap ring and verify the wheel spins freely without wobble. Installation typically takes 15 to 30 minutes per wheel. If you lack an arbor press, contact a local equipment repair shop.
