Frequently Asked Questions
Q: What does the EZ designation mean for the SU S654-EZ wheel?
A: The EZ designation indicates a tandem wheel configuration. The SU S654-EZ is designed for dual-wheel setups where two wheels are installed on the same axle position for load distribution. This design is common on heavy-capacity reach trucks and pallet jacks. Do not install a single S654-EZ wheel; the part is engineered for tandem use only.
Q: What are the specifications for the SU S654-EZ tandem wheel?
A: The SU S654-EZ has a 5.000 inch outside diameter and 3.625 inch width (127.00mm x 92.07mm). Inside diameter is 2.188 inches. Bore outside diameter is 2.4384 inches with a 0.67 inch bore depth. Material is Cushothane XL with a 3/8 inch radius tread profile. These dimensions are identical to the SU S654-A single wheel assembly.
Q: Can I use the SU S654-EZ on a truck not designed for tandem wheels?
A: No. The SU S654-EZ is engineered for tandem mounting. Installing a single S654-EZ wheel on a single-wheel axle causes misalignment and bearing stress because the wheel geometry and mass distribution assume two wheels are present. Always verify your truck design calls for tandem wheels before ordering.
Q: How many SU S654-EZ wheels do I need per axle and how are they mounted?
A: Install two SU S654-EZ wheels per axle. They are mounted side-by-side on a shared bearing hub or on two adjacent bearing positions. The dual wheels distribute load evenly and improve stability on uneven floors. Both wheels must be ordered and installed together. Installing only one wheel leaves the axle unbalanced.
Q: Does the SU S654-EZ require different maintenance than a single wheel assembly?
A: Maintenance is similar to single wheels. Inspect both wheels weekly for cracks, flat spots, and debris. Check bearing bolts monthly on both wheels and re-torque if loose. Both wheels should wear evenly; if one wheel shows more wear, the axle alignment may be off. Replace both wheels together to ensure uniform wear and handling.
Q: What is the load capacity of the SU S654-EZ tandem setup and when do I replace it?
A: The tandem configuration distributes load across two wheels, increasing total axle capacity (typically 6000 to 10000 pounds total depending on truck design). Replace the wheels when tread depth falls below 50 percent on either wheel, when cracks appear in the sidewall, or when the bearing develops play. Under normal use, tandem wheels last 18 to 30 months. Always replace both wheels at the same time.
