Frequently Asked Questions
Q: What are the cross-reference part numbers for the SU S9151?
A: The SU S9151 is equivalent to SU S9151-XL and SU S9151-XL-A. The manufacturer part number is SU S9151-XL. All three designations reference the same polyurethane load wheel with sealed precision bearing and steel core construction. Always verify the exact part number on your truck documentation or with the parts supplier when ordering replacements.
Q: What dimensions does the SU S9151 wheel have?
A: The SU S9151 specifications are not fully detailed in standard catalog data, but cross-reference to SU S9151-XL-A specifications, which use the same core wheel. Confirm exact diameter and width with the supplier before purchasing, as dimension variations affect fitment on different axle assemblies.
Q: Is the SU S9151 compatible with Raymond or Yale electric pallet jacks?
A: Compatibility depends on the specific model and model year. Raymond and Yale use wheels ranging from 4 inches to 8 inches in diameter. The SU S9151 can fit Raymond and Yale models if the diameter and width match the truck specification. Never assume compatibility based on brand alone. Obtain the OEM part number from the truck documentation and cross-reference it to confirm fitment.
Q: What should I check if the SU S9151 wheel does not roll smoothly or makes grinding sounds?
A: Lift the truck on jack stands and spin each wheel by hand. A smooth wheel should coast for 5-10 revolutions with minimal friction. If it stops abruptly or makes grinding or clicking sounds, the sealed bearing is likely damaged. Check for external debris around the bearing seal. If no external damage is visible, the bearing assembly has failed internally and the wheel must be replaced. Do not attempt to relubricate sealed bearings in the field.
Q: How often should SU S9151 wheels be inspected for wear?
A: Inspect wheels weekly in high-use operations (16+ hours per day) and monthly in standard duty (8 hours per day). Look for flat spots on the tread, visible chunking or gouges, and loss of roundness. If the wheel rims are visible (tread worn through), replace immediately. Worn wheels reduce braking efficiency and load control, creating a safety hazard.
