Frequently Asked Questions
Q: What wheels are included in the GWK-MJP55-CK complete kit?
A: GWK-MJP55-CK is a complete four-wheel kit comprising two ultra-polyurethane 70D hardness load wheel assemblies and two polyurethane steer wheel assemblies. All wheels arrive pre-assembled with bearings and mounting hardware. The two pairs are not interchangeable; load wheels must go on the rear axles and steer wheels on the front. This complete kit eliminates separate ordering and ensures all wheels are from the same production lot for consistent performance.
Q: Does GWK-MJP55-CK fit both Helmar and Maxx Jack MJP55 pallet jacks?
A: Yes. GWK-MJP55-CK is cross-compatible with both Helmar MJP55 and Maxx Jack MJP55 manual pallet jacks. Both manufacturers used identical wheel axle geometries and mounting configurations for this model series. Before ordering, confirm your pallet jack nameplate shows MJP55 designation. Do not assume compatibility based on similar appearance; verify the model number printed on the pump handle or frame.
Q: Can I purchase just the load wheels or steer wheels separately from this kit?
A: GWK-MJP55-CK is sold as a complete four-wheel assembly only. Individual wheel pair components are not available under this SKU. If you need only load wheels or steer wheels, contact the distributor for separate part numbers specific to those components. Mixing old and new wheels on the same pallet jack can cause handling inconsistencies and uneven wear.
Q: What is the rated load capacity when using GWK-MJP55-CK wheels?
A: GWK-MJP55-CK wheels are rated for the full 5500 lb capacity of Helmar and Maxx Jack MJP55 pallet jacks when properly installed. The 70D ultra-polyurethane load wheels and standard polyurethane steer wheels are engineered to handle sustained industrial use at rated capacity. Do not exceed the pallet jack nameplate capacity, as wheel assemblies are designed to distribute load equally across four points.
Q: How long does installation take, and what is the process?
A: Installation takes approximately 20-30 minutes total. Remove roll pins from all four existing wheel axles using a pin punch. Slide out the old assemblies. Align the new load wheel assemblies on the rear axles and steer wheel assemblies on the front axles. Re-install roll pins (included) into each axle. Test wheel rotation to confirm smooth operation before resuming service. No special tools are required beyond a small punch or pin driver.
