Frequently Asked Questions
Q: What is included in the SU S9814-A Load Wheel Assembly?
A: The SU S9814-A is a complete load wheel assembly for electric lift trucks, including the wheel hub, polyurethane tread, and all necessary mounting hardware. It is supplied as a ready-to-install unit and does not require additional components for fitment on compatible models.
Q: Which electric lift truck models are compatible with the SU S9814-A?
A: The SU S9814-A is engineered for electric pallet jacks, stackers, and powered lift trucks that use this specific wheel assembly size and mounting pattern. Verify your truck model documentation or contact us with your serial number and current wheel specifications to confirm exact compatibility before ordering.
Q: How do I install the SU S9814-A wheel assembly on my lift truck?
A: Remove the fasteners securing the existing wheel assembly using the appropriate wrench or socket. Lift the truck using a hoist or jack to safely remove the wheel. Slide the new SU S9814-A assembly onto the axle, align the mounting holes, and torque fasteners to manufacturer specifications (typically 35-45 ft-lbs for most electric lift truck wheels). Lower the truck and test operation under load.
Q: What load capacity does the SU S9814-A wheel assembly support?
A: The SU S9814-A is rated for continuous industrial duty on electric lift trucks. Load capacity is determined by your trucks design specification and axle rating, not the wheel alone. Refer to your lift trucks nameplate or manual for maximum rated load. Exceeding rated capacity will cause accelerated wear and void the warranty.
Q: How often should the SU S9814-A wheel assembly be replaced?
A: Lifespan depends on floor conditions, load weight, and daily cycle hours. Polyurethane wheels typically last 12-24 months in continuous 8-hour-per-day operation on average indoor floors. Rough concrete, outdoor use, or heavy loads reduce lifespan to 6-12 months. Inspect quarterly for flat spots, chunking, or tread separation. Replace when tread depth is visibly reduced or wheels no longer roll smoothly.
Q: What symptoms indicate the SU S9814-A needs replacement?
A: Watch for flat spots or worn areas on the wheel surface, visible chunks or tears in the polyurethane, resistance or grinding during operation, steering difficulty, or vibration at typical speeds. If the truck pulls to one side when rolling straight, one wheel may be worn unevenly. Replace both front or both rear wheels as a set to maintain balanced operation.
