Frequently Asked Questions
Q: Does GWK-YA55-CK include both load wheels and steer wheels?
A: Yes. GWK-YA55-CK is a complete replacement kit containing two 3 inch by 3.75 inch load wheels (70D ultra-poly) and two 7 inch by 2 inch steer wheels. This is a full wheel assembly replacement for Yale YA55 manual pallet jacks. If you need only load wheels or only steer wheels, you must order the individual kits GWK-YA55-LW or equivalent steer wheel component separately.
Q: What is the difference between 70D durometer load wheels and steer wheels?
A: Load wheels (70D, 3 x 3.75 inch) carry the pallet weight and require a softer compound for floor grip and shock absorption. Steer wheels (7 x 2 inch) guide direction and use the same 70D durometer for consistency. The larger diameter of steer wheels reduces rolling resistance and steering effort. Both compounds are ultra-polyurethane 70D, optimized for manual pallet jack operation on standard warehouse floors.
Q: Can I install GWK-YA55-CK wheels on other Yale models like YA50 or YA60?
A: No. GWK-YA55-CK is engineered exclusively for Yale YA55 manual pallet jacks. Wheel bore diameter, axle length, and fastener patterns differ between YA series models. Using incorrect wheels causes binding, poor steering, and bearing failure. Verify your jack nameplate shows YA55 before installation. Using parts on incorrect models voids warranties and creates safety hazards.
Q: What tools and how much time do I need to install this complete kit?
A: You will need a socket set, cotter pin removal tool, ball-peen hammer, grease, and jack stand. Installation takes 45 to 60 minutes for a complete wheel replacement (all four wheels). Remove the jack from service and support it on a work stand during replacement. All fasteners, pins, and precision bearings are included in GWK-YA55-CK. Do not work under a raised jack.
Q: How often should I grease the bearings on these wheels?
A: If bearings are sealed units, grease annually or every 500 operating hours, whichever comes first. Apply a small amount of lithium or NLGI-2 grease to bearing access points. If bearings are open designs (check your kit components), grease every 250 hours or monthly with light use. Over-greasing causes bearing drag and overheating. Listen for grinding or squeaking noise, which signals bearing wear.
Q: What is the maximum load capacity with GWK-YA55-CK wheels installed?
A: Maximum load is determined by the YA55 frame and hydraulic capacity, typically 3300 pounds for standard configurations. GWK-YA55-CK wheels are rated to support this capacity without exceeding bearing or polyurethane stress. Do not exceed nameplate load rating. Overloading causes accelerated wear on load wheels, bearing failure, and unsafe steering response. Check your YA55 documentation for exact capacity.
