Frequently Asked Questions
Q: What does the -A designation mean on the SU 629-A?
A: The -A designation indicates this is a complete load wheel assembly, meaning the polyurethane wheel is pre-bonded to the steel hub. The assembly is ready to install on the axle without additional machining or hub preparation. Order SU 629-A if you need a complete assembly or SU 629 if you only need the wheel tread.
Q: Can the SU 629-A be disassembled for hub reuse?
A: No. The SU 629-A wheel is permanently bonded to the hub and cannot be separated without destroying the wheel. If you need to reuse the hub, you must order only the SU 629 wheel tread and have it bonded to your existing hub by a specialist (not a field-replaceable procedure). Always replace the complete assembly for warranty compliance.
Q: What are the bore specifications for the SU 629-A assembly?
A: The SU 629-A has a 1.938 inch inside diameter with a 2.0467 inch bore outside diameter and 0.591 inch bore depth. The hub width is 5.873 inches. Measure your lift truck axle to confirm these specifications match. The 0.591 inch bore depth is shallower than the single wheel SU 629, so verify which assembly your equipment requires.
Q: What is the metric equivalent for the SU 629-A?
A: The SU 629-A measures 82.55 mm diameter x 150.80 mm width (metric equivalent for 3.25 x 5.937 inches). The assembly is 5.873 inches wide (hub width measurement). Use these metric dimensions when ordering parts for equipment manufactured outside North America.
Q: How should the SU 629-A be installed and what tools are required?
A: Installation requires an axle bearing puller to remove the old wheel assembly and a wheel press (or hammer and drift if no press is available) to seat the new assembly. Ensure the axle is clean and free of burrs. Install the bearing retaining ring or cotter pin per your lift truck manual. Do not use impact tools as they can damage the hub bore. After installation, verify the wheel spins freely with no wobble.
