Frequently Asked Questions
Q: Is GWK-ML55-LW compatible with both older and newer Mobile ML55 jacks?
A: GWK-ML55-LW is engineered specifically for newer Mobile ML55 series jacks. Older ML55 models may have different bearing sizes or axle configurations. Check your jack serial number and frame design before ordering. Contact the supplier with your jack serial number if you are unsure of the model generation.
Q: Why does GWK-ML55-LW come with two wheel assemblies?
A: GWK-ML55-LW includes two complete load wheel assemblies because pallet jacks have two rear load wheels. This kit replaces both rear wheels at the same time. Each assembly includes the wheel, 20mm ball bearing, axle, and fasteners ready to install on the rear frame position.
Q: What is a 20mm ball bearing and why is it important?
A: A 20mm ball bearing is the inner rotating component that allows the wheel to spin freely. The 20mm measurement refers to the bore diameter. Quality ball bearings reduce friction and extend wheel life. GWK-ML55-LW uses sealed 20mm bearings to protect against contamination. If a bearing fails, you will hear grinding or feel resistance when pushing the jack.
Q: Can I replace just one load wheel or must I replace both?
A: Best practice is to replace both load wheels at the same time to maintain equal rolling resistance. Replacing only one wheel can cause the jack to pull to one side during operation, creating uneven wear and unsafe handling. GWK-ML55-LW includes two wheels to support this maintenance standard.
Q: How do I install GWK-ML55-LW and what tools do I need?
A: Installation requires a wrench or socket set to match your jack fasteners, typically 9/16 inch or 12mm. Lift the jack using a floor jack or ramp, remove the axle fasteners, slide out the old wheels, and insert the new GWK-ML55-LW assemblies. Torque fasteners securely but do not over-tighten. Installation takes 15 to 20 minutes per wheel. Safety: always use proper lifting equipment and never work under an unsupported jack.
Q: Do GWK-ML55-LW wheels come pre-lubricated?
A: GWK-ML55-LW bearings are sealed and pre-lubricated from the factory. Do not disassemble or attempt to re-grease sealed bearings, as this can damage the seals and introduce contamination. If a bearing becomes noisy or stiff during use, replace the entire wheel assembly. Sealed bearings are maintenance-free under normal operating conditions.
