It is better to get a new unit. i have experience before using a second hand unit it does not last long. If the shaft is out balance then you can send it for dynamic balancing.
Ultimat,
You can call my contractor Nan they specialise in dynamic balancing. Most of my equipment is done by them. Just mention my name Michael Ong.
But if your shaft is bent than its better to change coz taking out the shaft and pump it back to position will not help. You will still get a bit of vibration after balancing. Good Luck.
