Frequently Asked Questions
Q: What is the SU 9107-A load wheel assembly?
A: The SU 9107-A is a Superior-brand replacement load wheel assembly designed for electric lift trucks. It is a direct aftermarket component that replaces OEM load wheels on compatible pallet jack models. It features a reinforced steel core with precision ball bearings for smooth operation under load.
Q: How do I install the SU 9107-A load wheel assembly?
A: To install: (1) Lift the truck and secure it on jack stands. (2) Remove the cotter pin and axle bolt from the existing wheel. (3) Slide the old wheel off the axle. (4) Position the SU 9107-A onto the axle, ensuring the bearing races seat properly. (5) Reinstall the axle bolt and cotter pin, tightening securely but not over-torquing, which can damage the bearing races. (6) Spin the wheel freely to confirm smooth rotation before use.
Q: When should I replace the SU 9107-A load wheel?
A: Replace the SU 9107-A when you notice flat spotting, visible cracks in the tread, or rough rotation indicating bearing wear. If the wheel does not spin freely or makes grinding noise, replacement is needed. Most load wheels last 2 to 5 years depending on load cycles and floor conditions. Rough surfaces accelerate wear.
Q: What maintenance does the SU 9107-A require?
A: Maintenance is minimal. Periodically inspect the tread for debris and clean with a dry cloth. Do not hose down or soak the wheel assembly, as water can damage the sealed ball bearings. Spin the wheel monthly to ensure smooth rotation. If rotation becomes stiff or makes noise, the bearings may require replacement.
