Nice! That's awesome. I'd love to learn how to weld, and what welders are best to use in different situations. A mig welder sounds like its the most versatile. Easy also, a 220v plug and your good to go.
I'll be interested in how you make out with the tube bender. That will definitely take care of your issue with making the right angled bends coming off your M90. You should be able to make a perfect fit now.
I have no idea if the bearing is pressed in or not. I'm going to have to take it apart and see. I'd love to have the parts required first though.
I wonder if this is the right rebuild kit.

I guess I'd have to take it to a machine shop to press the bearing on(And old one off), if a press is required. I will need a pully puller to get the pulley off. The pulley nut comes off easily, but a puller will be required to get the pulley off.
Haha yea its probably a press on.ive seen youtube vid of people doing it with a press but read it can damage the pulley or bearings when using a press.a special puleey is used to take it off and put it back on.also something i never heard rocket warn you about is those blades are synchronize and need to be kept together or put back in the same way,so if you pull the unit apart dont separate them.
Yes, on pulling the screws out, thats my concern. Im certain that if I manage to separate the screws (Gear even) I just made a boat anchor out of the blower. I just purchased the rebuild kit. So, I'll be doing some minor porting and polishing tot he m90 now. Nothing like Rocket, as I don't have the experience. I will smooth out the casting, and remove those two bolt castings to make that exit hole a bit larger.
Not to change the subject but on a side note about porting.you remember you said you dont know why they removed that bar on the bottom of my unit when they port it it?well found out why,they remove it for use on intercoolers,they said it allows more air flow through more suface of the cooler.they also suggest you open the inlet on your lower intake manifold to match the rectangle of the IC instead of the little square thats the size of the sc outlet.they said it made a significant decrease in temperature .i googled it and seem alot of people are split about removing it but half wasnt running a IC or half didnt enlarge there lower manifold.so im having it removed and going back and matching my LIM to my IChttp://spinningwheels-sc.com/eatonm90refresherkit.aspx
This is the kit I used. It is a small family company but the people are very polite and ship fast. Your kit is missing the rear main case bearings that support the rear of the rotors. I highly suggest that you get those too because they are usually the first to burn up. See the link below.

A press is required to get the bearings out of the snout and out of the rear case.
The snout pulley on the Thunderbird SC Eaton M90's is press on. Just get that big 3 jaw puller like you mentioned and you will be fine. If you press slowly then you won't marr the stock pulley so you can reuse it.
Pulling the front bolts out is not an issue.and separating the three main sections of the blower is a breeze for anyone with a little common sense and a rubber mallet. The middle plate contains the synchronized gears with rotors attached and all pressed together. There is no way for them to just fall apart, lose timing, or otherwise separate so don't worry about that at all. Once you have it apart you will see what I am talking about and understand why taking this blower apart into its 3 main sections isn't hard at all. It may take some whacks with the mallet and prying with a flathead screwdriver but once you have them separated by about 1/8" you can just pull them apart. The snout housing will pop off pretty easily too. Try to be a little careful when pulling the middle bearing plate/rotor assembly out of the rear main case. You don't want the rotors banging into and scratching the inside of the case as you pull them out. Once that is out you can set it aside into a plastic bag. All of the rebuild or porting that you can do are in the rear main case and the snout itself.
Just a note going back to your original issue of having a leak after sitting. Chances are that you just needed to take the 3 sections apart, clean up the mating surfaces, reapply some anaerobic sealant, and bolt them back together. But it isn't a terrible idea to rebuild the blower since you will already have it apart so you know it will be fresh after install.
I keep a pretty large personal library of articles and publications, etc of different things including Eaton rebuild articles. If you PM me your email addy I can send you some of what I have so you don't feel like you are flying blind. Some searching around in the internet should yield good info on rebuilding these units too.

maybe its just the pic or im use to 3800 m90dont get me wrong not saying you over did it or anything like, that just saying it looks big compared to my 3800
YOURS

Just went back and saw this post
So looks like this was irrelevant to your chargers so that IC core from ZZ may be too larger for you all.

Rocket, whats a bearing press look like. Could I get one at a reasonable price that would work for the M90?
oops....looks like a hydraulic floor press is needed.
There are ways to work around using a larger than needed core. Now if it were too small then that may pose an issue but a quick call to ZZP will yield those dimensions. If it is not wide enough then that Bell Intercoolers core will work for sure once some end tanks are welded or brazed on.
I can give you a ruff measurements if you cant get ahold of them.there pretty good on customer service tho

Thanks guys, It does look like the only way to rebuild the snout is to use a hydraulic press. I found one for $160.00
I bet it would cost me that in labor to have someone else do it. Figures. If only I could find someone that had one I could borrow.
I would not feel comfortable attempting to bang these bearings out with sockets and a hammer. Blowers are high speed units, and any bearing damage at all would be a very bad thing.
Rocket, how do I replace rear main case bearings?
Any info I see is on the gen 5, and it looks like some drilling and tapping, then using a grease gun to push the bearings out. Is that the way our older ones are done?
I took the M90 apart tonight, and found the reason for the oil leak....No sealant was used when the snout went together. There wasn't much oil in there (Maybe 3-4 ounces).
Also, the oil had no smell. Its not the same smelly stuff I hear people talk about. Maybe the bearings are still good...Maybe not. Theres a few strikes against them based on what I found.
I still think its best practice to rebuild though. No telling what other surprises there are. I might pack up the rebuild kit (Minus the oil), snout, and bearings for shipment to Rocket. I think cost of shipping will be lower with the blades removed, and packed in a smaller box.
