Frequently Asked Questions
Q: What electric lift truck models does the SU 250 load wheel fit?
A: The SU 250 is designed for compact electric pallet jacks and walkie stackers with standard hub configurations. Verify your truck mounting bracket diameter and axle width before ordering. If your truck uses a quick-change wheel system, confirm the interface type matches.
Q: Is SU 250 equivalent to any other brand load wheel?
A: SU 250 cross-references to Yale EZ305, Crown WC-5, and Hyster EW-224 load wheels for equivalent duty. Always verify the hub bore diameter and tread width on your existing wheel before substituting. If the bore is 2.25 inch or larger, check compatibility with your bearing type.
Q: What load capacity does the SU 250 handle?
A: SU 250 supports up to 4000 pounds per wheel in standard duty electric truck applications. Exceeding this limit accelerates tread wear and bearing failure. Four-wheel configurations distribute load across all wheels, so total truck capacity is approximately 16000 pounds when all wheels are rated equally.
Q: How do I know when to replace the SU 250 wheel?
A: Replace when tread depth drops below 0.125 inch, when you observe flat spots or uneven wear, or when the wheel develops a wobble during operation. A wobbly wheel indicates bearing failure. Do not weld or attempt to repair a failed wheel; replacement is required for safety.
Q: What installation tools do I need for the SU 250?
A: You need a 7/16 inch socket, a hydraulic jack rated for at least 1 ton, and a wheel puller if the wheel is pressed onto the axle. Do not force a pressed wheel by hand. Lift the truck 12 inches off the ground before removing or installing wheels. Retorque the axle nut to 35 foot-pounds after installation and verify no movement.
Q: Can I use the SU 250 on both front and rear axles?
A: Yes, the SU 250 is rated for front and rear duty on most electric jacks. However, some trucks require thinner wheels on the front for steering clearance. Measure your available space before ordering. If your truck specifications call for different front and rear sizes, do not mix them.
