Frequently Asked Questions
Q: What components are included in the SU 671-XL-A assembly?
A: The SU 671-XL-A is a complete pre-assembled wheel kit including the 6-inch polyurethane wheel, sealed ball bearing, axle cartridge, snap ring, and retaining clip. All components are factory-matched and pre-lubricated. This is a drop-in replacement assembly.
Q: When should I choose SU 671-XL-A instead of SU 671-XL wheel alone?
A: Use SU 671-XL-A if the bearing is damaged, the axle is bent, or you want a full assembly replacement to eliminate mixed component ages. If only the wheel tread is damaged and the bearing spins freely with minimal play, replace with SU 671-XL wheel only to save cost.
Q: How do I install the SU 671-XL-A assembly?
A: Remove the old assembly by sliding it off the frame mounting point and disconnect the axle clip. Slide the new SU 671-XL-A assembly into the frame pocket, ensuring the axle cartridge seats fully. Reattach the retaining clip and tighten the mounting bolts to 30 ft-lbs. Do not over-torque as it will crack the plastic axle housing.
Q: Is the SU 671-XL-A bearing sealed and maintenance-free?
A: Yes. The SU 671-XL-A bearing is sealed and does not require re-lubrication. It is maintenance-free for its service life of 2,000 to 3,000 operating hours. Do not attempt to open the bearing or add grease as this will void the warranty and compromise the seal.
Q: Can I use SU 671-XL-A to replace the wheel assembly on a Yale NR035 truck?
A: The SU 671-XL-A fits Yale NR035 models. However, verify the frame pocket dimensions match a 6-inch wheel diameter before ordering. If your truck uses 5-inch wheels, the assembly will not fit. Contact the manufacturer or check your truck manual for wheel size.
Q: What is the warranty on SU 671-XL-A?
A: The SU 671-XL-A carries a 12-month manufacturer warranty from date of purchase against bearing defects and material failure. This warranty does not cover wear from normal use, damage from overloading, or contamination. Keep your proof of purchase to file a warranty claim.
