Load Wheel Assembly
Frequently Asked Questions
Q: What truck models is the SU S250-A Load Wheel Assembly compatible with?
A: The SU S250-A is designed for Toyota and equivalent electric lift trucks with 6-inch wheel wells and standard spindle specifications. Verify your truck serial number range and axle configuration before ordering. Cross-reference against Yale, Hyster, and Crown equivalents if your truck is not a Toyota. Incompatible fitment will result in binding or excessive play.
Q: What is the load capacity and wheel diameter for the SU S250-A?
A: The SU S250-A assembly supports up to 5000 lbs per wheel when properly installed on a balanced axle. Wheel diameter is 6 inches with a 1-inch bore. Do not exceed rated capacity as overload will cause premature seal failure and bearing wear. Operating temperature range is 20F to 140F.
Q: Does the SU S250-A come pre-assembled or do I need to install bearings and seals?
A: The SU S250-A is supplied as a complete wheel assembly with bearings, seals, and retaining hardware installed. No bearing installation is required. Simply remove the old wheel, slide the axle through the bore, and secure with the included cotter pin and nut. Tighten to 45-55 foot-pounds. Do not over-tighten as this damages bearings.
Q: What maintenance is needed for the SU S250-A and how often?
A: Inspect wheel assembly weekly for cracks, wobble, or unusual noise. Check bearing play monthly by grasping the wheel and trying to move it side-to-side at 3 and 9 o clock positions. Slight play is normal. If wheels bind or make grinding sounds, bearings are worn and the assembly must be replaced. Typical lifespan is 3-5 years with normal duty use.
Q: What is the equivalent part number if SU S250-A is not available?
A: Direct equivalents include Yale 8193-8 and Hyster 0152157 for identical performance. However, verify bore size and bolt pattern match your truck. Crown 043313 and Toyota 87401-87405 may fit but spindle diameter differs slightly. Always test-fit before committing to purchase. Mismatched assemblies will not roll true.
