Frequently Asked Questions
Q: What trucks use the SU S674 load wheel and what is the OEM equivalent?
A: The SU S674 is an OEM direct-fit replacement for electric pallet jacks and reach trucks using this wheel size. The OEM part number is also SU S674. Measure your current wheel diameter and width 6.000 inches by 3.625 inches or 152.40mm by 92.07mm before ordering to confirm fit.
Q: What material is the SU S674 wheel and how does Cushothane XL perform?
A: The SU S674 uses Cushothane XL, a polyurethane material with solid wheel shell construction. Cushothane XL provides good traction on most floor types, resists oil and grease, and offers longer life than standard urethane. It is suitable for indoor and light outdoor warehouse use.
Q: Can the SU S674 be used as a replacement for wheels on different brands of forklifts?
A: The SU S674 is designed for specific OEM applications. Do not use on other brands or models without verifying bore diameter, shaft type, and load rating match your equipment. Using an incorrect wheel can cause loss of control and safety hazards.
Q: What are the bearing specifications for the SU S674?
A: The SU S674 has precision bearing seats and comes with pre-pressed bearings matched to the 2.238 inch inside diameter bore. Bore depth is 0.669 inch on each side. The outer bearing diameter is 2.4384 inches. Do not modify the bore or attempt to install non-standard bearings.
Q: How do I diagnose if the SU S674 wheel needs replacement?
A: Spin the wheel by hand; it should rotate smoothly for 5-10 seconds without grinding noise. Check for flat spots, cracks, or chunks missing from the tread. Listen while the truck moves for squeaking or grinding. If the truck pulls to one side, the bearing may be damaged. Replace immediately if any of these symptoms appear.
Q: What is the tread profile 3/8 Radius on the SU S674 and why does it matter?
A: The 3/8 inch radius tread profile is the curved contact surface of the wheel. This shape provides better grip on concrete and tile compared to flat wheels, and reduces shock when rolling over small debris. The radius is optimized for the load rating of your truck; do not substitute wheels with different profiles.
