Frequently Asked Questions
Q: What are the key specifications for the SU 9812-XL-A load wheel?
A: The SU 9812-XL-A is a 3.25 inch diameter by 6.01 inch width load wheel with Cushothane XL polyurethane material. Dimensions: inside diameter 1.938 inch, bore depth 0.584 inch, hub width 6.01 inch, bore outside diameter 2.0467 inch. The XL-A designation may indicate a specific assembly variant, so verify against your truck manual.
Q: Can the SU 9812-XL-A replace the standard SU 9812-EZ wheel?
A: The SU 9812-XL-A has the same nominal dimensions as the SU 9812-EZ. However, the XL designation suggests a different specification level or load class. Always verify the OEM part number in your truck manual before substitution. Consult the manufacturer if your manual specifies SU 9812-EZ; do not assume XL-A is interchangeable without written approval.
Q: What does the A suffix indicate on the SU 9812-XL-A wheel?
A: The A suffix typically designates a specific variant within the XL load class, such as a modified hub design, alternate bearing type, or supply channel. Full technical documentation for the A variant is not readily available online. Contact your distributor or the wheel manufacturer with the part number to obtain detailed specifications and confirm fitment for your truck.
Q: How do I diagnose if the SU 9812-XL-A wheel is worn and needs replacement?
A: Replace the wheel if you observe flat spots greater than 0.5 inch in diameter, visible cracks or chunks missing from the tread, hardening of the material (reduced bounce when pressed), loss of traction, or steering wobble. A worn wheel will also squeal during turns. Rotate wheels front to rear every 6-12 months to extend lifespan and detect uneven wear early.
Q: What is the correct procedure to install the SU 9812-XL-A wheel on an electric lift truck?
A: Power down the truck and secure it with wheel blocks and a lift on a stable surface. Remove the axle retaining pin or snap ring. Slide the old wheel off the axle. Inspect the axle bore and hub for wear or corrosion; clean if needed. Slide the SU 9812-XL-A wheel fully onto the axle, aligning the bore. Reinstall the retaining pin or snap ring and verify it is seated. Spin the wheel by hand to confirm smooth rotation before lowering the truck.
