Frequently Asked Questions
Q: Is SU S9107-A a plug-and-play replacement?
A: SU S9107-A comes as a complete pre-assembled load wheel with bearing hub ready for installation. However, you must verify that the axle bore matches your trucks hub diameter and that the bearing type (greaseable vs. sealed) is compatible with your truck maintenance requirements. Check your truck manual for the exact bore size before ordering.
Q: What bearing configurations are available for SU S9107-A?
A: SU S9107-A may be ordered with either greaseable bearings or sealed non-greaseable bearings depending on your truck model and maintenance schedule. Greaseable versions require periodic lubrication. Sealed versions are maintenance-free but cannot be relubricated if dry. Confirm the correct configuration with your truck manufacturer before installation.
Q: Can I reuse SU S9107-A if only the tread is worn but the hub is good?
A: No. SU S9107-A is a bonded assembly; the tread material cannot be separated from the aluminum hub. If the tread is worn but the hub and bearings are serviceable, you may be able to order the wheel component separately (SU S9107) instead of the full assembly. Contact the manufacturer to confirm if loose components are available.
Q: What are the installation steps for SU S9107-A?
A: Lift the truck safely. Remove the old wheel by unbolting it from the axle hub. Slide SU S9107-A onto the axle, align the bolt holes, and torque the bolts to the manufacturer specification (typically 45 to 65 foot-pounds, depending on truck model). Spin the wheel to confirm free rotation. Do not operate the truck until all wheels are replaced and torque is verified.
Q: How often does SU S9107-A need maintenance?
A: If your assembly has greaseable bearings, add grease every 250 operating hours or per your truck maintenance schedule. Sealed bearing versions require no lubrication. Inspect the wheel and bearing for wear every 500 operating hours. Replace when tread depth reaches 0.25 inch or if bearing play exceeds 0.010 inch.
Q: What is the typical lifespan of SU S9107-A?
A: Lifespan depends on load, surface conditions, and maintenance. Under typical conditions, SU S9107-A will last 1500 to 3000 operating hours. Concrete surfaces cause faster wear than smooth warehouse floors. Overloading the truck, inadequate bearing lubrication, or misalignment will significantly reduce lifespan.
