Frequently Asked Questions
Q: What is the difference between SU S233 and SU S233-A?
A: SU S233-A is a complete load wheel assembly that includes the wheel, hub, bearings, and seals as one unit. SU S233 is the wheel only. Use SU S233-A if the hub or bearings are damaged. SU S233-A installs faster if you do not have access to bearing removal tools.
Q: Is SU S233-A a direct replacement for a damaged SU S233 wheel?
A: Yes, if the axle shaft, snap rings, and bearing bores are undamaged. If the axle is bent or cracked, install a new axle assembly rather than wheel replacement alone. Always inspect the axle carefully before attempting assembly replacement.
Q: Can I install SU S233-A wheels on both ends of the axle, or do I need matching pairs?
A: For even load distribution and consistent handling, always install matching wheel assemblies on both sides of an axle. Mismatched wheels cause uneven wear and can create steering and braking imbalance on powered trucks.
Q: What tools and safety steps are required to install SU S233-A?
A: Tools needed: hydraulic lift, snap ring pliers, and a 3/4 inch socket set. Steps: lift truck frame, remove the snap ring from the axle shaft, slide the old assembly off, align the new SU S233-A on the axle, and install the snap ring fully. Always lock the snap ring in place. Never work under an unsupported truck.
Q: Do I need to repack bearings or add grease when installing a new SU S233-A assembly?
A: SU S233-A assemblies come pre-greased at the factory. Do not disassemble or repack. If noise develops after installation, remove the wheel and inspect for bearing damage, which indicates a defective unit. Contact the supplier for warranty replacement.
