Frequently Asked Questions
Q: What components are included in the SU S1130-XL-A assembly?
A: The SU S1130-XL-A includes the polyurethane wheel, sealed bearing cartridge, steel hub, and all spacers and retaining hardware pre-assembled at the factory. All components are matched for fitment and do not require adjustment. This is a plug-and-play replacement for most Toyota, Nissan, and Yale models. Verify your truck model and axle diameter before order placement to ensure correct fit.
Q: Is the SU S1130-XL-A pre-assembled and ready to install directly?
A: Yes, the SU S1130-XL-A arrives fully assembled. Remove the old assembly from your truck axle, clean the axle shaft with a wire brush, slide the new assembly on, reinstall the axle nut, and secure with a new cotter pin. Installation takes 10 to 20 minutes per wheel if you have basic tools. Do not press on the bearing cartridge; only press on the hub itself. Pressing on the bearing will damage the seals and cause premature failure.
Q: Can I replace just the polyurethane wheel if the bearings are still good?
A: If you have the SU S1130-XL-A assembly and only the wheel is worn, you can purchase the SU S1130-XL wheel separately and replace the poly tread. This requires pressing the old wheel off and the new wheel on using a bearing press. This is labor-intensive and not cost-effective unless the wheel cost is significantly lower than a full assembly replacement. Consult your parts supplier for the economics on your specific order.
Q: Is the SU S1130-XL-A compatible with all 24V and 36V lift truck systems?
A: The SU S1130-XL-A wheel assembly is voltage-agnostic and works on any DC voltage system. However, compatibility is model and truck-specific, not voltage-specific. You must match the wheel bore, hub width, and axle diameter to your truck. A 24V Toyota and a 36V Nissan may use completely different wheel assemblies despite similar truck size. Always verify model compatibility with the manufacturer before purchase.
Q: What are the warning signs that the SU S1130-XL-A bearings are failing?
A: Grinding noise from the wheel, visible wobble or lateral play when hand-spinning the wheel, steering resistance, and heat radiating from the hub are all indicators of bearing wear or contamination. Spin each wheel by hand monthly; rotation should be smooth and silent. If noise is audible or movement is rough, the bearing cartridge is damaged. Sealed bearings cannot be serviced and must be replaced as part of the assembly. Do not operate the truck further; bearing failure can cause sudden wheel lockup.
