Frequently Asked Questions
Q: What lift truck models are compatible with the SU S671-XL-A load wheel assembly?
A: The SU S671-XL-A is compatible with Yale ERP (electric reach), Toyota 8FGCU, and Nissan UGF series trucks with 48V systems. Always verify your truck nameplate and serial range before ordering. XL designation indicates extra-wide tread for stability on uneven warehouse floors.
Q: Is the SU S671-XL-A a complete wheel assembly or just the wheel?
A: SU S671-XL-A is a complete load wheel assembly, which includes the wheel, sealed bearing cartridge, and axle collar. This is a plug-and-play replacement; you do not need to transfer bearings or spacers from the old wheel.
Q: What is the weight capacity and tire material of the SU S671-XL-A?
A: The SU S671-XL-A supports up to 5500 pounds per wheel and features a polyurethane elastomer tire rated for indoor use on concrete. Operating temperature range is 32F to 104F. Do not exceed load limits or operate in freezing conditions without inspection.
Q: How do I install the SU S671-XL-A on my truck?
A: Lift the truck on jack stands, remove the axle pin or castle nut from the damaged wheel, slide the old assembly off, align the new SU S671-XL-A hub onto the axle shaft, and reinstall the pin or nut. Torque castle nuts to 45-55 foot-pounds. No wheel bearing adjustment is required.
Q: How long does the SU S671-XL-A wheel assembly last before replacement?
A: With normal warehouse use (light to medium duty, 5 days per week), the SU S671-XL-A lasts 18-24 months before polyurethane tire wear requires replacement. Sealed bearings are typically good for the life of the wheel. Inspect for flat spots or chunks missing from the tire every 6 months.
Q: What is the difference between SU S671-XL-A and SU S673-A?
A: SU S671-XL-A is wider (extra-large footprint) and rated for 5500 lb capacity, while SU S673-A is standard width for 4200 lb capacity. Do not mix both types on the same axle as this causes handling instability. Choose based on your load class and truck model compatibility.
