Frequently Asked Questions
Q: What is the difference between GWK-BF-LW and GWK-BF-CK?
A: GWK-BF-LW is a load wheel kit only, containing two wheels, axles, bearings, and fasteners for the Mighty Lift ML55. GWK-BF-CK is a complete kit that includes both load wheels and steer wheels. If you only need to replace the load wheels and your steer wheels are in good condition, order GWK-BF-LW for cost savings. If you need to replace steering wheels as well, order the complete GWK-BF-CK kit.
Q: Does GWK-BF-LW fit ML5500 or only ML55?
A: GWK-BF-LW is listed for the Mighty Lift ML55 model. The product notes compatibility with ML55 slash 5500 variants, indicating ML5500 may be an alternate designation for the same truck. Verify by checking your equipment nameplate. If your nameplate does not match, contact parts support with the serial number. Incompatible wheels can fail to mount correctly and create unsafe operating conditions.
Q: What durometer rating do the load wheels have on GWK-BF-LW?
A: GWK-BF-LW features ultra-polyurethane wheels with 70D durometer hardness, delivering exceptional wear resistance and durability. The 70D rating is one of the hardest standard polyurethane compounds available. This makes GWK-BF-LW ideal for high-cycle operations on abrasive surfaces. Wheels will last longer than standard 92A but will require slightly more operator effort to push the jack due to increased rolling resistance.
Q: What materials are used in the GWK-BF-LW bearings and axles?
A: GWK-BF-LW includes hardened steel bearing races and hardened steel axles, providing durability under heavy loads. The lock ring material is spring steel, which maintains tension on the wheel assembly. These components are industrial-grade and rated for continuous service. Do not apply lubricants to the bearing raceways; clean dry bearings are preferred. If bearings become rough or noisy, replace them and inspect the axle for bending.
Q: Can I install GWK-BF-LW wheels myself or do I need a technician?
A: GWK-BF-LW installation is straightforward and can be done by a trained operator or technician. Lower the jack and secure it on wooden blocks. Unbolt the old wheels, remove them, clean the axles, install new bearings and wheels, and reinstall fasteners. The process takes about 30 minutes for both load wheels. Use hand wrenches only; do not use pneumatic tools which can over-tighten fasteners and damage axles. Verify wheels spin freely and track straight before operating.
Q: What is the load capacity with GWK-BF-LW wheels installed?
A: Load capacity remains the same as your original ML55 jack, typically 5000 pounds. Wheels do not determine truck capacity; the hydraulic pump and frame do. The 70D Ultra-Poly wheels are rated to support the trucks full capacity with excellent durability. Never exceed the nameplate load limit even though these wheels are very hard and durable. Exceeding capacity stresses the hydraulic system and frame welds, creating safety hazards.
