Product Description
This complete wheel kit is designed to replace worn or damaged wheels on Big Joe pallet jacks. It includes two Ultra-Poly (70D) load wheel assemblies and two poly steer wheel assemblies, complete with bearings, axles, and fasteners for easy installation. The high-quality materials ensure durability and easy movement under heavy loads, while the specified 70D durometer polyurethane offers greater resilience compared to standard options, avoiding shattering common with nylon.

Frequently Asked Questions
Q: What wheels are included in the GWK-ALT50-CK complete kit?
A: The GWK-ALT50-CK includes two Ultra-Poly 70D load wheel assemblies and two 92A durometer poly steer wheel assemblies. Each assembly comes with bearings, axles, and fasteners ready for installation on Big Joe ALT50 manual pallet jacks.
Q: Is the GWK-ALT50-CK compatible with any other pallet jack models?
A: The GWK-ALT50-CK is specifically designed for Big Joe ALT50 manual pallet jacks. For other models, verify your jack model and serial number before ordering, as wheel compatibility varies by manufacturer and load capacity rating.
Q: What is the difference between the 70D load wheels and 92A steer wheels?
A: The 70D load wheels are harder durometer polyurethane providing greater resilience and resistance to shattering under heavy loads. The 92A steer wheels are softer, offer better floor traction and steering control, and reduce noise during operation.
Q: Do I need special tools to replace the wheels with this kit?
A: Basic tools are required: a socket wrench set, jack stand or mechanical lift, and possibly a gear puller for bearing removal. All fasteners are included. If bearings are seized, penetrating oil and a bearing press simplify removal. Consult your jack manual for torque specifications.
Q: How long do these wheels typically last before replacement?
A: Lifespan depends on load, surface conditions, and usage frequency. On average, 70D polyurethane wheels last 2 to 4 years in moderate industrial use. Inspect wheels quarterly for flatspotting, cracks, or excessive wear. Replace immediately if floor traction is lost or steering becomes difficult.
Q: Are these wheels non-marking and suitable for finished floors?
A: Yes, the polyurethane wheels in this kit are non-marking and safe for finished floors, warehouses, and clean room environments. The material will not leave black marks on polished concrete or epoxy surfaces under normal operating conditions.
