Load Wheel Assembly
Frequently Asked Questions
Q: What does SU S249-A include, and is it plug-and-play for my lift truck?
A: SU S249-A is a complete load wheel assembly with wheel, hub, and fasteners. Installation requires removing the old assembly from the axle and sliding the new assembly onto the axle, then securing it with the axle bolt. Before installation, verify that your lift truck axle bore and bolt pattern match SU S249-A specifications. Consult your equipment manual for proper installation torque and procedure.
Q: How do I remove the old wheel assembly and install SU S249-A safely?
A: Raise the lift truck with a floor jack and support it on jack stands rated for the load. Do not work under an unsupported vehicle. Locate the axle bolt connecting the wheel assembly to the axle. Use the appropriate wrench or socket to remove the bolt. Slide the old assembly off the axle. Align the hub bore of SU S249-A with the axle shaft and slide it on. Replace the axle bolt and tighten it to the specified torque, typically 30 to 50 foot pounds depending on bolt size. Spin the wheel by hand; it should rotate freely without binding.
Q: Is SU S249-A equivalent to OEM assemblies from Raymond, Yale, Hyster, or Toyota?
A: SU S249-A may be equivalent to specific OEM models if dimensions and bolt patterns match. Do not assume interchangeability based on brand or model year alone. Cross-reference your lift truck model number with the parts supplier to confirm that SU S249-A is a valid replacement. Mismatched assemblies can cause steering problems or fail to secure properly.
Q: What is the lifespan of SU S249-A, and what conditions shorten it?
A: Load wheel assembly lifespan depends on usage intensity and floor conditions. Typical service life is 2 to 5 years with daily use in a warehouse. Wet floors, outdoor use, or rough surfaces reduce lifespan significantly. Worn or flat-spotted wheels should be replaced before they fail. Replace both left and right assemblies at the same time to maintain steering balance and prevent uneven wear on the next pair.
Q: Can I replace just the wheel if the hub on my SU S249-A is still good?
A: Yes. If the hub is not cracked or damaged, you can order the wheel separately as SU S249 and reuse the hub. You will need a wheel puller tool to remove the old wheel from the hub if it is tight. Press the new wheel onto the hub using the same bore diameter. Inspect the hub bore for dirt or damage before installation; a contaminated bore reduces wheel life.
Q: What is the difference between SU S249-A and SU S248-XL-A?
A: SU S249-A and SU S248-XL-A are different wheel sizes designed for different lift truck models. SU S248-XL-A is 3.25 inch diameter by 6 inch width. SU S249-A size must be verified with the parts supplier or your equipment manual. Never interchange wheel sizes; mismatched wheels cause steering drift, premature wear, and potential equipment damage.
