Frequently Asked Questions
Q: What does GWK-MJ55-LW include and is it a complete wheel kit?
A: GWK-MJ55-LW is a load wheel kit only, not a complete wheel kit. It includes two durable ultra-polyurethane load wheels (70 Shore D per ASTM D2240) with molded tread over reinforced hub, and bearing assemblies. It does not include steer wheels, axles, or fasteners. Use this SKU only if you are replacing worn load wheels while keeping existing steer wheels and hardware.
Q: Is GWK-MJ55-LW compatible with the MJ55-N48 or MJ55-W48 models?
A: GWK-MJ55-LW is designated for the standard MJ55 frame. The MJ55-N48 and MJ55-W48 are extended-fork variants with different wheel mounting geometry. Do not force GWK-MJ55-LW into N48 or W48 jacks. Use GWK-MJ55-N48-LW for N48 models and GWK-MJ55-W48-CK for W48 models. Verify fork length (48 inch, 20.5 inch width) before ordering.
Q: How do I check if GWK-MJ55-LW wheels will fit my fork ends?
A: GWK-MJ55-LW wheels have specified mounting clearance to fit MJ55 series fork ends. Measure your existing wheel diameter and width, and confirm your axle pin diameter. If your existing load wheels are worn but still mounted, the replacement will fit the same axle and bearings. When in doubt, contact your supplier with your jack serial number.
Q: Can I install GWK-MJ55-LW myself or do I need a technician?
A: Installation is straightforward if you are experienced. You need a socket wrench, possibly a bearing puller, and knowledge of axle removal. If you do not have bearing-press equipment, take the jack to a service center. Improper bearing installation or axle torque will cause premature failure and safety risk. Estimated labor is 30 minutes per wheel if you have the tools.
Q: What is the typical replacement cost and lifecycle for GWK-MJ55-LW?
A: GWK-MJ55-LW is a consumable part. In standard warehouse duty, load wheels wear every 18 to 36 months depending on floor type (smooth vs. rough concrete). Regular inspection every 6 months will detect flat spots or bearing noise before failure. Replacing wheels before bearing damage saves the entire jack from damage and extends equipment life by 5 to 10 years.
