Worn bearings would not cause a motor to run fast. I would approach diagnosing this in this way.
- Determine if the speed is fast for both 33 and 45.
- Determine if the speed is faster for 45 to the same extent as it is for 33.
- Determine what specific speed range for 33 and 45 you can adjust over.
- Determine whether the speed is steady even though fast.
From the answers to the above, one can pin down the area of the system causing the problem. Feel free to post these and I’ll give you my diagnosis.
