Frequently Asked Questions
Q: What is the difference between GWK-UL5500-LW and the complete GWK-UL5500-CK kit?
A: GWK-UL5500-LW contains only the dual load wheel assemblies with bearings and axles. Use this kit if your steer wheels are still serviceable. GWK-UL5500-CK is the complete system with both load and steer wheels. Choose GWK-UL5500-LW when load wheels have worn but steering components are sound.
Q: Are the bearings pre-installed on GWK-UL5500-LW?
A: Yes. GWK-UL5500-LW arrives with precision ball bearings pre-installed in the wheel hubs. The hardened steel axles are included and ready to mount. You only need to slide the assembly onto the jack frame mounting points and secure with the supplied fasteners. No bearing installation or pressing is required.
Q: Can GWK-UL5500-LW be installed without removing steer wheels?
A: Yes. GWK-UL5500-LW load wheels mount independently of steer wheel systems on the Ultra UL5500. You can replace load wheels while steering components remain in place. Jack must be lowered fully and blocked securely before work. Use bearing grease-compatible cleaner on axles; do not use solvent that may damage bearing seals.
Q: What is the maximum load rating with GWK-UL5500-LW installed?
A: GWK-UL5500-LW maintains the Ultra UL5500 jack rated capacity of 5500 pounds. Load wheels are engineered for the full platform load distribution. Do not exceed this limit. Overloading degrades wheel hardness faster and shortens bearing life. Always verify combined load including pallet weight.
Q: How often should GWK-UL5500-LW wheels be greased during service?
A: Sealed precision ball bearings on GWK-UL5500-LW do not require routine greasing—they are sealed at factory. If you notice resistance or grinding at bearing, the seal has failed and the wheel assembly must be replaced. Do not attempt to force grease into sealed bearings; this damages seals and creates debris.
Q: Will GWK-UL5500-LW work on an older serial range Ultra UL5500?
A: GWK-UL5500-LW is cross-compatible across all Ultra UL5500 production runs that use the same axle spacing and bore diameter. Check your jack serial plate. If the jack is labeled UL5500 and shows no frame modifications, fitment is direct. Verify axle-to-frame spacing matches 3.75 inch wheel width before ordering.
