Here is MY advice and I know it won't be popular but here it is.
Pull that POS out and have it checked out. You have NO IDEA what is in it and what has been done. It's been a shaker since day one. Stop pissing away time and pull it out. The rotating assembly has not been CORRECTLY balanced. In fact, it sounds like you don't have a clue as to what you have.
Can't tell you how many times guys have paid for a balance job and didn't get it. Fixed many of them
You got screwed. Pull it out and get on with it.
Post back on what you do and what you find. But I'd bet everything RustyRatRod has I'm correct.
That's just the kind of guy I am!!! O.P.M Other People's Money...I spend it like water.
