Frequently Asked Questions
Q: What applications is the SU 9152-XL-A designed for?
A: The SU 9152-XL-A is a 5.000 inch by 2.875 inch load wheel assembly engineered for electric lift truck applications, particularly Class 3 sit-down counterbalanced forklifts. The narrower 2.875 inch width makes it ideal for tight warehouse aisles and narrow load centers. Verify your truck model specifications before ordering to confirm the 3.1491 inch bore diameter and 0.983 inch bore depth match your existing hub assembly.
Q: Is the SU 9152-XL-A compatible with my Yale, Crown, or Toyota lift truck?
A: The SU 9152-XL-A cross-references to Yale YL-582028491, Crown L509152, and Toyota 42-7FD15 on equivalent specifications. However, do not assume compatibility based on brand alone. Verify bore diameter (3.1491 inch), bore depth (0.983 inch), and your truck serial range. Some models shifted mounting standards between production years. Request the original equipment part number from your truck nameplate before purchasing.
Q: What is the load rating for this wheel assembly?
A: The SU 9152-XL-A is rated for loads up to 1250 pounds per wheel under Class 3 duty cycle (operator plus load, minimal travel distance). This 5-inch diameter wheel is designed for indoor, level floor operation. Do not exceed the load rating or use on outdoor, uneven surfaces. Overloading accelerates wear on the 3/8 radius tread profile and can damage the hub assembly.
Q: How do I replace the SU 9152-XL-A wheel on my truck?
A: Lift the truck on a jack stand to remove load from the wheel. Use a 7/16 inch socket to remove the retaining nut on the wheel axle. Slide the old wheel off and inspect the axle and hub for damage or excessive wear. Slide the new SU 9152-XL-A wheel onto the axle, ensuring the bore seats fully against the hub. Reinstall the retaining nut, torque to 35-40 foot-pounds, and spin the wheel to confirm free rotation. If the wheel does not spin freely, the bore depth may be incorrect.
Q: What maintenance does the SU 9152-XL-A require?
A: Greaseable SU 9152-XL-A models require lubrication every 250 operating hours using a multi-purpose lithium grease. Non-greaseable sealed models require no maintenance but cannot be disassembled. Inspect the 3/8 radius tread profile every 6 months for uneven wear or flat spots. If wear exceeds 1/8 inch depth or tread separates from the hub, replace the wheel immediately. Check axle play at the bearing surface and replace if lateral movement exceeds 0.062 inch.
Q: Why is my SU 9152-XL-A wheel showing flat spots or excessive wear?
A: Flat spots indicate the truck was loaded and left stationary for extended periods, concentrating load pressure on one wheel section. This is normal but shortens wheel life. Excessive radial wear on the 3/8 radius profile suggests overloading, worn bearings, or misalignment. Check that the truck frame is square and the wheel rotates freely without binding. If bearing play exceeds 0.062 inch measured at the hub, replace bearings and inspect the axle for bending. Replace the wheel if tread depth falls below 1/8 inch.
