Frequently Asked Questions
Q: What models and serial ranges does the SU 673-EZ-A assembly fit?
A: The SU 673-EZ-A Load Wheel Assembly is compatible with Yale, Hyster, and similar electric lift truck lines using the EZ series frame (check your truck nameplate for exact model compatibility). Verify your current wheel bore diameter and axle width before ordering; this assembly ships pre-configured for standard 2.238 inch bore applications.
Q: Is the SU 673-EZ-A shipped as a complete bolt-on assembly?
A: Yes. The SU 673-EZ-A includes the wheel, sealed bearings, axle sleeve, and mounting hardware. Installation requires only removal of the old wheel assembly and bolt-on attachment (approximately 15 minutes per side with basic hand tools). No shimming or bore adjustment is needed if replacing an identical OEM assembly.
Q: Can I purchase just the wheel without the assembly?
A: No. The SU 673-EZ-A is sold only as a complete assembly. If you need the wheel alone, order SKU SU 673-XL. If your existing bearings and axle are serviceable, you can reuse them with the SU 673-XL wheel replacement.
Q: What is the maximum load rating for this assembly?
A: Load capacity depends on truck configuration and drive wheel count. The SU 673-EZ-A assembly is rated for up to 6,000 lbs per wheel on four-wheel drive models and 4,500 lbs on three-wheel models. Consult your truck manual or contact your distributor with your truck serial number for exact rating.
Q: How do I know if the bearings need replacement instead of just the wheel?
A: Spin the wheel by hand. If it rotates freely with minimal drag and stops smoothly, bearings are serviceable. If you hear grinding, feel roughness, or the wheel has excessive wobble (more than 1/8 inch play), replace the assembly. Do not re-pack sealed bearings; they are non-serviceable.
Q: What is the typical service life of the SU 673-EZ-A assembly?
A: Under normal warehouse conditions (indoor, level floors, 8-hour shifts), expect 3 to 5 years service life. Outdoor or rough-floor use reduces life to 18 to 36 months. Inspect wheels quarterly for tread wear, scoring, or flat spots. Replace when tread depth falls below 1/8 inch or visible damage appears.
