Frequently Asked Questions
Q: What machines does the SU 9138-XL load wheel fit?
A: The SU 9138-XL is designed for electric lift trucks and powered pallet jacks. Always verify your machine model and bore size before ordering. Check your existing wheel specifications on the jack nameplate or cross-reference documentation to confirm compatibility.
Q: How do I know if my SU 9138-XL wheel needs replacement?
A: Replace the wheel if you see flat spots, cracking, uneven wear, or hard chunks missing from the tread. If the wheel wobbles during operation or makes grinding noises, the bearing is likely failed and replacement is needed. Visual inspection should show smooth tread without cracks or separation.
Q: Can I use the SU 9138-XL wheel as a drop-in replacement?
A: The SU 9138-XL is typically a direct replacement on compatible models with matching bore diameter. However, verify the axle configuration and load rating on your specific machine. If your equipment has been modified or has non-standard mounting hardware, verify fitment before installation.
Q: What is the maximum load capacity for the SU 9138-XL wheel?
A: Load capacity depends on bearing type, bore size, and hub construction. Do not exceed the rated capacity of your complete jack assembly, which is typically marked on the machine nameplate. Overloading causes premature bearing wear and can result in wheel failure during operation.
Q: How should I maintain the SU 9138-XL wheel during normal operation?
A: Inspect the wheel weekly for debris, buildup, or cracks in the tread. Keep the tread clean to maintain traction and identify wear early. Check bearing play monthly by lifting the jack and spinning the wheel by hand. Any grinding sound or excessive wobble indicates bearing failure.
