Frequently Asked Questions
Q: What components are included in the SU 674-EZ-A load wheel assembly?
A: SU 674-EZ-A is a complete assembly that includes the 6.000 x 3.625 inch Cushothane XL wheel pre-bonded to the hub, sealed bearings, and pre-drilled mounting points. No additional hub or bearing installation is required. This is a true plug-and-play replacement for defective or worn load wheel assemblies.
Q: How does SU 674-EZ-A differ from ordering SU 674-EZ separately?
A: SU 674-EZ-A saves labor because bearings are pre-installed and sealed. If you order SU 674-EZ alone, you must remove the wheel from the old hub, install it on a new hub, and set up bearings and seals. SU 674-EZ-A is faster for field replacement but costs more. Choose SU 674-EZ-A if your hub is damaged; choose SU 674-EZ if only the wheel tread needs replacement.
Q: What is the typical lifespan and maintenance interval for SU 674-EZ-A?
A: Under standard warehouse conditions, expect 2 to 4 years of service before tread wear or bond degradation requires replacement. Sealed bearings require no lubrication. Inspect every 6 months for tread wear, sidewall cracks, or noise during operation. Do not attempt to relubricate or disassemble sealed bearings. Replace the entire assembly if bearing noise develops.
Q: Can the SU 674-EZ-A be used on Class 2 and Class 3 trucks?
A: SU 674-EZ-A is designed for standard industrial lift truck duty. Verify your truck class in the equipment manual before ordering. Class 2 trucks (narrow aisle pallet jacks) typically use this size. Class 3 (walk-behind pallet jacks) may require different wheel sizes. Always cross-reference your truck model and frame type before installation to prevent overload and premature failure.
Q: What mounting dimensions do I need to verify before ordering SU 674-EZ-A?
A: Measure the axle pin diameter and the distance from the truck frame to the wheel mounting point. Verify that the 6.000 inch outside diameter and 3.625 inch width fit your truck frame without interference. Check that existing bolt hole or pin hole patterns on your truck frame match the assembly. If uncertain, photograph your current wheel assembly and provide the truck model number to verify fitment.
Q: Is the SU 674-EZ-A wheel non-marking?
A: Cushothane XL provides very low marking on clean warehouse floors and concrete. However, on dirty or oily floors, some residue transfer is possible. Cushothane XL is formulated to minimize black marks. If your application is ultra-clean flooring (food, pharmaceutical, clean rooms), consult product specs or test a sample wheel first. Standard warehouse floors generally show minimal to no marking.
