LOAD WHEEL
Frequently Asked Questions
Q: What pallet jack models use the SU S9870 load wheel?
A: The SU S9870 is a standard load wheel for Crown, Toyota, Raymond, and Yale electric pallet jacks manufactured between the late 1990s and early 2010s. The exact models vary by bore diameter and axle width. Contact us with your machine model and serial number, and we will confirm if the SU S9870 is the correct replacement.
Q: How do I check if the SU S9870 will fit my current machine?
A: The safest method is to remove the old wheel and measure the bore diameter (the inside hole where it slides onto the axle) and the overall width. Compare these dimensions to the SU S9870 specifications. If your old wheel is still in good shape, bring it to us or provide a clear photo; we can match it to the SU S9870 or suggest an alternative.
Q: What are the material and durability characteristics of the SU S9870?
A: The SU S9870 is manufactured from industrial-grade polyurethane or rubber compound designed for warehouse and material handling duty. It resists oil, cutting, and abrasion. Under typical daily use (8-12 hours, light to moderate loading), expect 3-5 years of service life. In light-duty or intermittent use, the wheel may last 5-7 years. Replace immediately if flat spots, cracks, or chunks appear.
Q: Can I swap the SU S9870 with a newer model wheel if the dimensions are close?
A: Not recommended. Even if bore and width dimensions appear similar, newer wheels may have different tread patterns, hardness, or bearing configurations that do not perform correctly on older axles. Always specify the exact OEM or equivalent part number for your machine. Mixing old and new wheel designs can cause pulling, vibration, and premature wear.
Q: Does the SU S9870 require any special tools or steps to install?
A: Installation is basic: lift the jack on a hoist or jack stand, remove the wheel pin (usually a cotter pin and cotter key), slide off the old wheel, and slide the SU S9870 onto the axle. Replace the pin and cotter key. Use a hammer to set the pin; do not force it. No special tools required beyond a wrench and hammer. Both wheels should be replaced together to prevent uneven wear and pulling.
Q: What symptoms indicate the SU S9870 needs replacement?
A: Replace the SU S9870 if you notice: the jack pulls or drifts to one side; flat spots or flat-sided wear on the wheel; cracks or chunks missing from the tread; or if the wheel does not roll smoothly when lifted. If both wheels are worn evenly but the machine still operates, wait until flat spots appear before replacing. Replacing prematurely wastes parts; replacing too late creates safety and productivity loss.
