Frequently Asked Questions
Q: Does GWK-ECON-CK fit my Mobile ECO I-55 pallet jack?
A: Yes. GWK-ECON-CK is the direct replacement wheel kit for Mobile ECO I-55 manual pallet jacks. It matches OEM part number MO870321. Verify your jack is an ECO I-55 model before ordering. If you have an ECO I-55 but are unsure of your current wheel condition, check for flat spots, cracking, or uneven wear.
Q: What is the difference between GWK-ECON-CK and GWK-ECON-LW?
A: GWK-ECON-CK uses 70D durometer polyurethane wheels (ultra-hard), which are better for cold storage and corrosive environments where non-marking properties matter most. GWK-ECON-LW uses 95A durometer wheels (softer), which provide smoother rolling and less strain on equipment. If your facility is indoors with mild conditions, use GWK-ECON-LW. Use GWK-ECON-CK for harsh or frozen environments.
Q: Are the 70D wheels rust-resistant?
A: The polyurethane tread itself does not rust. However, the underlying wheel core and axle may corrode in highly corrosive environments. GWK-ECON-CK wheels are non-marking and designed for cold storage where rust concerns exist, but if you are in a salt or chemical spray environment, inspect the axles and bearing areas regularly and apply protective coating as needed.
Q: What tools do I need to install GWK-ECON-CK?
A: You will need a socket wrench set, a bearing puller or two-jaw puller, and a rubber mallet. The kit includes all fasteners. Installation takes about 30 minutes per wheel pair. Remove the cotter pin or snap ring, press out the old wheel, clean the axle, and press the new wheel on until it seats fully. Reinstall fasteners hand-tight first, then torque to specification per your jack manual.
Q: How long will GWK-ECON-CK wheels last?
A: 70D durometer wheels typically last 3 to 5 years in cold storage with normal use (moving loads up to the jack rated capacity daily). Lifespan depends on load, floor condition, and frequency. Rough or uneven floors shorten life. Inspect for wear every 6 months. If wheels are flat-spotted, cracked, or reduced more than 1/4 inch in diameter, replace them immediately to prevent safety and handling issues.
