Frequently Asked Questions
Q: What are the exact dimensions and specifications of the SU 653-A load wheel assembly?
A: The SU 653-A is a 5 inch outside diameter by 2.875 inch width load wheel assembly with a 3.149 inch bore diameter and 0.591 inch bore depth. The wheel features a 3/8 radius tread profile, 4.25 inch tread width, and 95A Shore hardness polyurethane (Cushothane XL compound 302). The internal bore outside diameter is 2.045 inches. This assembly includes shoulder bearings manufactured from high-strength steel.
Q: Which electric lift truck models does the SU 653-A load wheel fit?
A: The SU 653-A is designed as a direct replacement load wheel for electric lift truck applications from manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify that your equipment uses a 3.149 inch bore and accepts a 5 x 2.875 inch wheel dimension before ordering. Check your truck documentation or measure the existing wheel to confirm fitment.
Q: What material properties does the Cushothane XL compound 302 offer?
A: The Cushothane XL polyurethane compound 302 at 95A Shore hardness is engineered for heavy load transfer applications in debris-prone, wet, and cold storage environments. This material provides good load capacity, reduced vibration, and improved traction on wet or contaminated floors. The compound resists abrasion and maintains performance in temperatures typical of refrigerated warehouses and dock areas.
Q: How do I install or replace the SU 653-A load wheel assembly?
A: Remove the truck from service and place it on a level surface. Use a hoist or lift to raise the wheel off the ground. Remove the snap ring or retaining clip holding the old wheel assembly, then slide the wheel off the axle shaft. Clean the axle shaft to remove any debris. Slide the SU 653-A assembly onto the axle, ensuring the bore aligns correctly, then reinstall the snap ring or retaining clip. Verify the wheel rotates freely before placing the truck back in service.
Q: What is the typical maintenance schedule for the SU 653-A load wheel assembly?
A: Inspect the load wheel monthly for debris accumulation, cracks, or flat spots on the tread. Clean the wheel and shoulder bearings with a damp cloth to remove dirt and salt residue, particularly after use in wet or cold storage areas. Monitor bearing condition; if the wheel becomes difficult to turn or makes grinding noises, the bearings may need replacement. Replace the entire assembly when tread depth reduces significantly or visible damage appears. Proper maintenance extends wheel life to 1-2 years depending on usage intensity.
