Frequently Asked Questions
Q: Will GWK-AC20-CK wheels fit other manual pallet jack brands besides NobleLift AC20?
A: No. GWK-AC20-CK is engineered specifically for the NobleLift AC20 mounting configuration. The wheel core fastener pattern, axle diameter, and bearing pocket dimensions are OEM-matched to AC20 only. If you have a different jack model, verify the exact make and model before ordering. Using mismatched wheel kits will cause improper fit, bearing preload issues, and safety hazards.
Q: What is the difference between the 70D load wheels and 92A steer wheels in this kit?
A: The 70D Ultra-Poly load wheels are harder and more wear-resistant for rolling capacity. The 92A polyurethane steer wheels are softer for better grip and control during steering. This combination allows the jack to handle heavy rolling loads while maintaining directional precision on concrete, tile, and factory floors. Do not swap them or substitute alternatives.
Q: Are the bearings pre-installed and sealed on the GWK-AC20-CK assemblies?
A: Yes. All four wheel assemblies come with sealed precision ball bearings pre-installed on the axles. The bearings are maintenance-free and cannot be repacked. If bearing noise or drag develops during use, the entire wheel assembly must be replaced. Do not attempt to disassemble or lubricate the bearing seals.
Q: What tools and steps are required to install GWK-AC20-CK wheels?
A: Installation requires a socket set, wrench, and jack stand. Step 1: Raise the pallet jack and secure with jack stands. Step 2: Remove cotter pins and fasteners from the existing wheel assembly axles. Step 3: Slide off the old wheels. Step 4: Slide the new wheel assemblies onto the axles, aligning the mounting flanges. Step 5: Replace fasteners and cotter pins. Tighten to hand-firm plus one-quarter turn. Do not overtighten. Step 6: Verify wheels rotate freely before lowering the jack.
Q: How long should GWK-AC20-CK wheels last in normal warehouse operations?
A: Typical lifespan is 2 to 4 years with daily use in standard indoor environments such as carpet and concrete warehouses. Lifespan decreases with constant outdoor exposure, rough surfaces, or sustained heavy loading beyond jack capacity. Check wheels quarterly for flat spots, cracks, or bearing play. Replace immediately if flat spots exceed 1/8 inch or if the jack feels unstable when turning.
Q: Can I replace just the load wheels and keep the existing steer wheels?
A: No. The GWK-AC20-CK is a complete wheel kit designed and tested as a matched set. Mixing old and new wheels creates uneven weight distribution, unpredictable handling, and accelerated wear on remaining components. Always replace all four wheels at the same time.
