shaft bent on fan assembly

just installed my rebuilt aa130 all piped up and now running. when runnin g the fan was rattling and had some vibration. i took everything apart and noticed the shaft was bent on my new fan assembly. i know the cost of a new assembly is significant, i was wondering if anyone here knows if i can just replace the shaft and put everything back togvether? it appears that everything is attatched with set screws to the shaft and if i removed the back plate off the boiler took the fan off the shadft then proceeded to remove brass bushings etc. and replace them on the new shaft. if this is possible does anyone have dimensions of shaft before i remove it? if not and i do have to remove and replace entire assembly, any reason not to buy used fan assembly? any one have a used fan assembly within reasonable distance of the williamsport area?
question two: my doghouse setup allows for the auger/coal tube to stick out of the doghouse by about 4or5in will this cause permanent damage to my auger/boiler? my dads has been this way for years seems to be fine? since now my boiler is all piped in moving may not be easy. any thought opinions on this?
thank you jack

If the assembly is "new", call whoever you bought it from and tell them the fan shaft is bent. That isn't acceptable on a new or rebuilt unit.

On the bright side, if you are located in the Williamsport area you can always bring the entire fan assembly right to Axeman Anderson.

The shaft is available separately, and like Rob said, you are located in the home town of Axeman Anderson, so parts are just
a short drive away.
Should be an easy fix.
Not sure how the shaft could have been bent, seems unlikely, unless the fan assembly was dropped ?

i purchased the unit rebuilt. it has a gaurentee from the man that rebuilt it but i purchased it second hand from the gentleman that bought it from him and never used it. so this is the first time it has been in service since the rebuild. i am very confident i didnt bend the shaft during transport but i am also confident thats what the gentleman will say i did since he didnt have a shipping braket with the unit when i bought it, to which i question he said it would be fine. i will try contacting him but he is about three hours from me. and again i am doubtful anyone will have any interest in my issue. based off of your responces i assume it is possible to replace the shaft only? how difficult is this to do myself? have either of you ever done this before? do you reccomend it?

do i need to replace the gaket if i take off the back panel?
does the shaft have any ket ways on it?
reason i ask i have access to 1/2" shaft

If the gasket is new you should be ok. The shaft is easily replaced but take your time and take measurements for fan to box . There are a few parts in there but it really pretty simple. If you are in williamsport you can always have axeman do it as well.
