Frequently Asked Questions
Q: Is GWK-CPI-CK compatible with Clark CJ55 pallet jacks or only Wesco CPI?
A: GWK-CPI-CK is designed for Wesco CPI model pallet jacks only. It is not compatible with Clark CJ55 jacks. The load wheel size (3 inch by 3.75 inch) and steer wheel size (7 inch by 2 inch) on the CPI model differ from the CJ55. Installing CPI wheels on a CJ55 jack will cause binding, poor steering, and safety hazards. Always verify your jack manufacturer and model before ordering.
Q: What does Ultra-Poly 70D mean for the load wheels in GWK-CPI-CK?
A: Ultra-Poly is a premium polyurethane formulation. 70D means 70 Shore D hardness on the durometer scale. Harder wheels (higher number) last longer and roll smoother but transmit more vibration. 70D is ideal for high-volume, continuous-use warehouses. The load wheels experience the most wear and stress, so the 70D specification in GWK-CPI-CK ensures extended service life under heavy loading.
Q: Do I need to remove the jack hydraulic unit or disassemble the base frame to install GWK-CPI-CK?
A: No. You can replace wheels with the jack on a flat surface without removing the hydraulic unit. Lift the jack slightly using blocks or a hoist to relieve weight on the wheels. Remove axle fasteners and slide old wheels off. Slide new wheels onto axles, ensuring they seat fully. Reinstall and tighten fasteners snugly (do not over-tighten). Installation takes approximately 45 minutes for all four wheels.
Q: Are the steer wheels in GWK-CPI-CK the same hardness as the load wheels?
A: No. GWK-CPI-CK includes two Ultra-Poly 70D load wheels and two Poly steer wheels. Steer wheels are softer (typically 60D to 65D durometer) to allow easier turning and smoother directional control. Load wheels carry weight; steer wheels control direction. Using the same hardness for both would make steering difficult and cause tracking issues. Never swap steer and load wheels.
Q: What is the maximum load capacity with GWK-CPI-CK wheels installed?
A: The wheel kit itself does not change the jack load rating. GWK-CPI-CK maintains the Wesco CPI jack rated capacity (typically 5500 pounds nominal). Verify your jack nameplate for the exact capacity. Overloading beyond the rated capacity will damage wheels, bearings, and hydraulic components regardless of wheel condition. Replace worn wheels before load capacity is affected by dragging resistance.
