3 3/8 X 2 5/8 Poly Load Wheel
Frequently Asked Questions
Q: Is the SU S322 a direct replacement for the Yale YL-582031652?
A: Yes. SU S322 is the equivalent part for Yale YL-582031652 and provides the same 3 3/8 inch diameter poly load wheel with 2 5/8 inch width. Always verify the wheel bore diameter (typically 5/8 inch or 3/4 inch) matches your lift truck model before ordering.
Q: What lift truck models use the SU S322 load wheel?
A: The SU S322 fits most electric pallet jacks and walk-behind lift trucks with 3 3/8 inch wheel wells. Common models include Yale MP20, MP25, Toyota 8FD and 8FG series up to 3000 lb capacity, and Crown WP2000 series. Verify your truck manual or the existing wheel size before purchase.
Q: What causes premature wear on the SU S322 poly wheel?
A: Premature wear stems from uneven tire pressure in paired wheels, incorrect wheel alignment causing sideways dragging, or overloading beyond truck capacity. Inspect wheels for flat spots or uneven edge rounding. If one wheel shows wear faster than its pair, check for bent axle or bent wheel spindle.
Q: How do I remove and install the SU S322 wheel?
A: Remove the wheel by loosening the axle nut (typically 1/2 inch wrench) and sliding the wheel off the spindle. Slide the new SU S322 wheel onto the spindle, ensuring the bearing sits flush. Retighten the axle nut firmly but do not over-torque, which can crack the bearing. The wheel should spin freely with minimal side play.
Q: What is the load rating and durability of the SU S322?
A: The SU S322 supports up to 3000 lb per wheel pair on most lift trucks. Poly wheels typically last 2 to 4 years under normal use (8 hour daily operation). Operating above capacity or on rough concrete surfaces reduces lifespan to 12 to 18 months. Inspect wheels monthly for cracks or flat spots.
Q: Does the SU S322 work on both load and steer wheel positions?
A: No. The SU S322 is designed for load wheels only (rear wheels on pallet jacks). Steer wheels require the SU S329 or equivalent. Installing a load wheel in the steer position causes poor turning radius and can damage the steering linkage.
