Frequently Asked Questions
Q: What is the difference between SU 652-XL and SU 652-XL-A?
A: The SU 652-XL-A is a complete wheel assembly that includes the polyurethane wheel, pre-installed bearings, and hub components. The SU 652-XL is the wheel only. Choose the SU 652-XL-A if you need a complete drop-in replacement or if existing bearings are damaged.
Q: Is the SU 652-XL-A assembly maintenance-free?
A: The SU 652-XL-A comes with sealed bearings that are pre-installed and lubricated. Under normal conditions, the bearings require minimal maintenance. However, inspect the assembly periodically for debris and ensure the wheel rotates freely without grinding noise.
Q: Can I use the SU 652-XL-A assembly on any electric lift truck?
A: The SU 652-XL-A is compatible with electric lift trucks that accept the specified bore diameter and mounting hardware. Confirm your truck model and axle configuration before purchase. Some models may require adapter sleeves or modified mounting brackets.
Q: How is the SU 652-XL-A installed on an electric lift truck?
A: Lift the truck safely using a jack stand. Remove the old wheel assembly by unbolting or pressing out the axle pin. Slide the SU 652-XL-A assembly onto the axle, aligning the bore with the axle shaft. Reinstall fasteners and verify the wheel rotates freely without wobbling before lowering the truck.
Q: What do I do if the SU 652-XL-A assembly makes noise after installation?
A: A grinding or clicking sound indicates bearing failure or misalignment. Inspect the wheel bore and axle for debris. If noise persists, the bearing cartridge may be damaged and the assembly should be replaced. Do not operate the truck; bearing failure can cause wheel lock-up.
