Frequently Asked Questions
Q: What is the difference between GWK-MJ55-N48-CK and the standard GWK-MJ55-CK?
A: GWK-MJ55-N48-CK is engineered for the N48 variant, which has a 48 inch fork length and 20.5 inch fork width. The standard MJ55-CK uses shorter forks. N48-CK includes 7 inch diameter dual nylon steer wheels and scaled load wheel assemblies matched to the extended-fork geometry. Do not substitute standard MJ55-CK parts into an N48 frame; the wheels will not fit the fork ends correctly.
Q: Does GWK-MJ55-N48-CK support the same 5500 lb load capacity?
A: Yes. GWK-MJ55-N48-CK is rated for 5500 lb capacity, matching the standard MJ55-N48 pallet jack design. The extended fork length does not reduce load rating. All materials—ultra-polyurethane load wheels (70 Shore D), sealed bearing assemblies, hardened steel axles, and roll pins—are engineered for the full 5500 lb working load.
Q: How do I install GWK-MJ55-N48-CK and what tools do I need?
A: Installation follows standard wheel-kit replacement procedure. You will need socket wrench set, bearing puller (if needed), hammer, and blocks to safely lift the jack frame. The kit includes sealed bearing assemblies and roll pins; some techs prefer to press bearings fresh to ensure proper seating. Total labor is 2 to 3 hours for a complete kit swap. Always verify bearing torque specifications before operation.
Q: Can I use GWK-MJ55-N48-CK wheels on a standard MJ55 (non-N48)?
A: No. The N48 wheels are sized and mounted for the extended 48 inch fork length. Attempting to fit N48 wheels to a standard MJ55 frame will cause improper clearance, bearing misalignment, and safety hazards. Always verify your jack model and fork length before ordering. Use the correct part number for your specific configuration.
Q: What is the expected service life of GWK-MJ55-N48-CK?
A: Under normal material-handling duty (8-hour shifts), load wheels last 18 to 36 months; steer wheels last 24 to 48 months. Extended-fork models (N48) sometimes experience slightly faster wear due to increased lever arm stress on the front wheels. Inspect wheels every 6 months for flat spots, bearing noise, or polyurethane cracking. Preventive replacement extends pallet jack life significantly.
