Frequently Asked Questions
Q: What comes in the SU S673-A load wheel assembly package?
A: SU S673-A includes the polyurethane wheel, sealed bearing cartridge, axle collar, and spacer ring. Everything is pre-assembled and ready to slide onto your axle shaft. No bearing transfer or adjustment is required.
Q: What is the load capacity and tire diameter of the SU S673-A?
A: SU S673-A supports 4200 pounds per wheel and is 8 inches in diameter by 6.5 inches wide. Polyurethane tire is rated for indoor concrete use. Do not exceed weight limits or use on outdoor rough terrain.
Q: Is SU S673-A equivalent to Yale YL-582031623 or Crown WL-2436?
A: SU S673-A is functionally equivalent to Yale YL-582031623 for electric reach trucks and Crown WL-2436 for certain pallet jacks, but always verify your truck model nameplate before ordering. Cross-references vary by truck manufacturer and year, so confirm part compatibility with your original equipment manual or parts diagram.
Q: How do I install the SU S673-A on my lift truck?
A: Jack up the truck on stands, remove the axle cotter pin and nut from the worn wheel, slide off the old assembly, position the new SU S673-A onto the axle shaft, align the hole in the collar, reinstall the nut, and secure with a new cotter pin. Torque to 40-50 foot-pounds. Install does not require special tools.
Q: How often should I replace the SU S673-A and how long does it last?
A: Under normal warehouse use (light to medium loads, 5 days weekly), the SU S673-A lasts 20-28 months before polyurethane tire wear becomes severe. Sealed bearings rarely wear out before the tire does. Inspect for flat spots, cracks, or missing chunks every quarter. Replace when tire thickness drops below 0.25 inches.
