Frequently Asked Questions
Q: What is the difference between SU S928 and SU S922-XL load wheels?
A: The SU S928 has a different bore diameter and load rating compared to the S922-XL. The S928 is designed for lighter-duty or smaller jacks, typically 1,500 to 2,500 lb capacity. Do not interchange them without verifying axle diameter and equipment nameplate specifications.
Q: Can I use the SU S928 on a Hyster or Jungheinrich electric jack?
A: Possibly, but only if your jack axle bore and load class match the S928 specifications. Hyster and Jungheinrich models vary widely in configuration. Verify your jack model number against the S928 compatibility list or provide your equipment serial number for confirmation.
Q: How do I diagnose a failing SU S928 load wheel?
A: Look for visible cracks, flat spots, or missing chunks from the tread. Listen for grinding or squealing when the jack operates. Try spinning the wheel by hand; it should rotate smoothly. If it binds, wobbles, or makes noise, the bearing is likely damaged and the entire wheel assembly should be replaced.
Q: What is the removal and installation process for the SU S928?
A: Remove the cotter pin and axle nut, then slide the wheel off the axle. If the wheel is corroded or seized, use a bearing puller or wheel puller. Clean the axle, apply a thin coat of multipurpose grease, slide the new wheel on, reinstall the nut and cotter pin, and verify free rotation. Ensure the axle is not bent before reinstalling.
Q: How often does the SU S928 require greasing and maintenance?
A: Grease the bearing every 500 operating hours or monthly, whichever comes first. Use standard lithium multipurpose grease. In wet or abrasive environments, increase frequency to every 250 hours. Inspect the wheel visually each time you grease it for cracks or wear.
Q: What is the typical service life of the SU S928 under normal operating conditions?
A: Under light to moderate duty use, the SU S928 typically lasts 18 to 36 months. High-impact or continuous operation may reduce life to 12 months. Heavy-duty or high-speed environments require more frequent inspection and replacement.
