Yes, I rebuilt my P600B because it was leaking a slight amount of oil past the oil seal. ATI will not give you any information or sell you any parts whatsoever, so you will need to do some research on what parts will work since you can't get their proprietary stuff. ATI wouldn't even give me a quote to inspect my unit, they just wanted me to send it in.
The high speed bearings are ~$75 ABEC 7 angular contact thrust bearings with a phenolic cage (the impeller moves upwards of 50,000rpm), the low speed bearings are regular ball bearings with a metal cage. You will need to do some measuring to figure out what oil seal you need but Napa came through for me with one from Chicago Rawhide. The impeller is pressed onto the main shaft. The impeller nut requires a special tool to remove, you might need to get creative. Take pictures as you take it apart and put fasteners into marked baggies so you know what goes where.
The cool thing is, since everything is press fit/interference fit..everything is machined with stops. So you press the bearing on until it's all the way on. And you press the impeller on until it's all the way on. Etc. The bearings are held in place with clips, and if those clips don't line up with the grooves in the housing, then you know something is wrong.. really easy actually.
If your Procharger explodes after I gave you some sort of false hope that you could rebuild it yourself, I take no responsibility for what I have just posted.
Or you can take the bearing numbers down to a bearing shop and see what they run... I've found that most of the stuff they use goes for a few $ if you buy it by pn from a normal shop not as a "supercharger bearing" from somone specializing in them

high speed bearings aren't cheap no matter where you get them from.....i'd be willing to bet its either a timken or a BCA bearing # though

That's what I did, I went to a place here called Johnson Bearing with my numbers and dimensions... they are a wholesaler that specializes in nothing but bearings. They were still pretty expensive (well, I consider $75 a bearing expensive, anyway).
procharger didnt charge us for looking at out p600b. they had it for 5 days an called us with the cost to rebuild it and it came back looking new.they've always anwsered our questions when we called long as we gave them the ser# number....Sam
And at that point, you weren't just talking about bearings and seals anymore, it was more like bearings, seals, impeller, and compressor housing, right?
the total was just under 1400.00 but we chewed it up pretty bad becuase we couldn't hear it until it went getting home.
What was the cause? Operator error or just worn out? How many miles between rebuilds on one of those things?
It seems that the SC shops are a lot like the turbo diesel shops, Harley shops, etc. They are tight-lipped and try to get everyone thinking that it is rocket science and only a select few can get the parts and do the actual work when in fact it is just cheap stuff that mostly anyone could do. I bet most of the hard parts are just from some generic turbo.

The impeller and compressor housings definitely aren't turbo pieces. They have a gear drive inside of them, 4 bearings and two shafts which obviously turbos don't have. I'm guessing about the only things that aren't proprietary ATI pieces are the bearings themselves... whether or not the other stuff is all made in-house, I don't know.
I just disassembled my p600b Procharger with 160k miles on it. It started to ruin belts rather quickly. I have found replacement bearings and one seal. The high speed seal seems to be made of solid Teflon and I have not found any type of seal like it.
I have enjoyed this supercharger very much and have found it to be very reliable.
Thanks,
Steve
