Frequently Asked Questions
Q: What is the cross-reference part number for SU 9164?
A: SU 9164 is directly equivalent to SUS9164-XL and Superior SU9164. When ordering replacement wheels, verify your lift truck model against all three part numbers, as some distributors reference one over the other. If you are upgrading from an OEM wheel, SUS9164-XL indicates the factory original.
Q: Can SU 9164 be installed on any electric lift truck?
A: No. SU 9164 is engineered for select Superior and compatible aftermarket electric lift trucks. Before installation, confirm your truck hub diameter and mounting type match the wheel specifications. Measure the hub bore and compare against the wheel center bore diameter. Mismatch will cause wobble or binding under load.
Q: What is the tread material and why does it matter?
A: SU 9164 features a polyurethane tread bonded to a steel hub. Polyurethane provides grip on smooth warehouse floors and resists abrasion better than rubber on concrete. Steel hubs offer durability under load cycles. If your truck shows signs of wheel slip or drift, worn polyurethane tread is likely. Replace both wheels on the same axle to maintain even handling.
Q: How long does an SU 9164 wheel typically last?
A: Lifespan depends on load, floor surface, and hours of use. In high-cycle warehouse operations with 2000+ hours annually, expect 3 to 5 years before tread wear becomes noticeable. Inspect monthly for flat spots, cracks, or separation between tread and hub. Proper wheel alignment and load balancing extend service life.
Q: What tools do I need to replace an SU 9164 wheel?
A: Most SU 9164 installations require a press fit. You will need a wheel puller (mechanical or hydraulic), a bearing/hub press, and a torque wrench. Do not use a hammer to drive the wheel onto the axle shaft, as this can damage the bearings. If your truck uses castle nuts or snap rings, have an appropriate socket set and spring tool available. Always wear safety glasses during removal and installation.
Q: What should I check if my truck pulls to one side after wheel replacement?
A: Pulling indicates uneven wheel installation or bearing preload. Verify both wheels on the same axle are seated fully on the shaft and torqued to spec. Check that the wheel is not rubbing the frame or brake assembly. If a new wheel pulls but the old wheel was fine, the new wheel hub bore may be out of spec. Contact the supplier for exchange or bearing re-shimming.
