Frequently Asked Questions
Q: What is the difference between SU 9149-EZ and SU 9149-EZ-A?
A: SU 9149-EZ-A is a Load Wheel Assembly designation. The -A suffix typically indicates a complete assembly configuration. Verify your truck documentation to determine which SKU is correct for your model. Ordering the wrong SKU may result in incompatible bore diameter or width.
Q: What is a Load Wheel Assembly and how does it differ from a single wheel?
A: A Load Wheel Assembly includes the polyurethane wheel mounted on a hub or core, ready for installation on an axle. It is a complete drop-in component. A single wheel is just the polyurethane tread. Assemblies save installation time and ensure proper centering on the axle. Confirm your truck requires an assembly, not just a wheel tread.
Q: Is SU 9149-EZ-A compatible with all electric pallet jack brands?
A: SU 9149-EZ-A is compatible only with trucks that have matching bore diameter and axle width specifications. Brands such as Yale, Crown, Still, Toyota, and Hyster use different wheel specifications depending on model and year. Verify the current wheel bore diameter and width dimensions before ordering. Do not assume cross-brand compatibility.
Q: What symptoms indicate SU 9149-EZ-A wheels are failing?
A: Watch for: difficulty steering or increased steering effort, visible flat spots or uneven tread wear, grinding or squeaking sounds when turning, chunks missing from the wheel, cracks in the polyurethane, or the wheel tilting inward or outward. Any of these conditions means the wheel assembly should be replaced immediately to prevent truck immobility or safety hazards.
Q: How is SU 9149-EZ-A installed on an electric lift truck?
A: Secure the truck on stands. Remove the retaining clip, cotter pin, or bolt from the axle. Slide the old assembly off. Clean the axle with a dry cloth. Check the axle for dents or scoring. Align the SU 9149-EZ-A bore with the axle and slide it on until it seats fully. Install the retaining clip, cotter pin, or bolt and tighten. Spin the wheel by hand to confirm it does not rub. No tools required beyond basic mechanics tools.
Q: What is the expected service life of SU 9149-EZ-A and what maintenance is required?
A: Service life is typically 12 to 18 months in standard duty applications, shorter in high duty cycle use. Maintenance includes monthly visual inspection for cracks or separation, quarterly cleaning with water and neutral soap, and checking the axle for straightness. Do not use pressure washers or strong solvents. If wheels develop flat spots or chunks, replacement is required. Regular cleaning extends service life by preventing chemical and salt degradation.
