Frequently Asked Questions
Q: Will GWK-MJ55-CK fit my Maxx Jack MJ55 pallet jack?
A: Yes. GWK-MJ55-CK is engineered specifically for Maxx Jack MJ55 manual pallet jacks. The kit includes steer wheels, load wheels, axles, and bearings matched to the MJ55 frame geometry and 5500 lb load capacity. Verify your jack frame matches MJ55 before ordering. Do not use on other Maxx Jack models without confirming frame compatibility.
Q: What materials are included in the GWK-MJ55-CK kit?
A: GWK-MJ55-CK includes ultra-polyurethane load wheels (70D Shore hardness), dual nylon steer wheels, hardened steel axles with powder coat ASTM A36 construction, precision ball bearings, and stainless fasteners. The frame is ASTM A36 structural steel with powder coat finish. All materials are selected for 5500 lb capacity performance.
Q: Is installation of GWK-MJ55-CK plug-and-play or do I need tools?
A: Installation requires basic hand tools: socket wrench set, hammer, and possibly a press for bearing installation depending on your shop setup. The kit includes roll pins and fasteners. If you do not have bearing-press capability, many field technicians use a bearing puller and installation tool. Total install time is typically 1 to 2 hours per jack. Safety: always lift the jack frame on blocks before wheel removal.
Q: What is the expected service life of GWK-MJ55-CK wheels?
A: Under continuous manual duty (8-hour shifts, standard warehouse loading), load wheels typically last 18 to 36 months before visible tread wear requires replacement. Steer wheels last 24 to 48 months. Service life depends on floor surface, load profiles, and maintenance. Inspect wheels every 6 months for flat spots, bearing play, or polyurethane degradation.
Q: Can I replace only the load wheels without replacing steer wheels?
A: Yes. GWK-MJ55-CK is sold as a complete kit, but individual load wheel and steer wheel assemblies are available separately. If you need only load wheels, contact your supplier for GWK-MJ55-LW (load wheels only). This approach saves cost if steer wheels still have tread and bearing function.
