Product Description
This wheel kit includes two Ultra-Poly Load Roller Assemblies (70D) and two Poly Steer Wheel Assemblies, complete with bearings, axles, and fasteners, designed to enhance the performance of pallet jacks. The 70D durometer wheels provide superior durability and ease of movement compared to standard 92A polyurethane wheels. This kit is compatible with ECO I-55 pallet jacks for optimal functionality in various environments, ensuring a non-marking, smooth ride while protecting your floors.
Compatibility: Fits pallet jacks made by Mobile, model ECO I-55. SKU: GWK-ECO-CK

Frequently Asked Questions
Q: Is GWK-ECO-CK compatible with all ECO I-55 pallet jacks, or are there serial number restrictions?
A: GWK-ECO-CK is designed for the ECO I-55 model line manufactured by Mobile. The kit fits standard ECO I-55 production units without serial number restrictions. However, if your jack has been heavily modified, has a non-standard chassis, or uses fork extensions wider than the original equipment, verify axle diameter and bolt hole spacing match before installation. Request a parts diagram from the manufacturer if you are uncertain about model compatibility.
Q: What is the difference between the load rollers and steer wheels in GWK-ECO-CK, and are they interchangeable?
A: Load rollers are larger diameter wheels rated to support the full weight of the load and are mounted at the front. Steer wheels are smaller and mounted at the rear, allowing directional control without bearing the full load. They are not interchangeable due to different axle diameters, bearing sizes, and mounting flange geometry. Installing them in the wrong position will cause steering to bind and load wheels to fail under weight.
Q: How do I diagnose whether load rollers or steer wheels are the problem on my ECO I-55?
A: For load roller failure, the jack becomes difficult to push forward, feels heavy even on level ground, or you hear grinding from the front wheels. Visually inspect for flat spots, cracks, or debris embedded in the polyurethane. For steer wheel failure, the jack pulls hard to one side during normal operation, steering is stiff or erratic, or you hear squealing from the rear. Manually spin each wheel; they should rotate freely without grinding or resistance. Replace any wheel that does not spin freely.
Q: What fastener specifications and torque values should I use when installing GWK-ECO-CK?
A: GWK-ECO-CK includes Grade 8 steel fasteners. Use a socket wrench set and torque all load wheel bolts to 40 to 50 foot-pounds and steer wheel bolts to 30 to 40 foot-pounds. Do not over-torque, which can crack the mounting flange or strip bolt threads. After 24 hours of operation, re-check fastener tightness to account for any settling of the polyurethane and mounting surfaces.
Q: Can GWK-ECO-CK wheels be used in cold storage or freezing environments?
A: Yes. The 70D Shore durometer ultra-poly wheels are rated for continuous use in cold storage at temperatures as low as 0 degrees Fahrenheit. Below 0 degrees Fahrenheit, the polyurethane becomes brittle and may crack; do not use the jack below this temperature. In cold storage, the wheels may feel slightly stiffer and require marginally more push force, but this is normal and does not indicate failure. Ensure wheels are free of ice buildup before operation.
