I know exactly what your saying.
What i meant was, i hope it doesn't blow, if it does, i hope it doesn't hurt anything else.
But if it does...i guess I'll fix it, and lesson learned.
I don't know the exact specs on the shaft, fins, etc.
But..the shaft and fins showed no signs of excessive wear, and everything was symmetrical.
After reassembling, shaft play was eliminated.
The original bearings however, did show wear, but i wouldn't think it was excessive. As they checked out about .150 thinner and 1/16" shorter than the replacement bearings
I do plan on testing it with a compressor, and about 150 psi of air blowing into the exhaust impeller while upside down and full of oil, the plan is to get the shaft spinning to the approximate speed of normal operation, and feel for vibration.
If anything feels abnormal, I'll definitely send her off
