B&M 250 refresh
 

Guys I need the low down on replacing the seals, bearings and teflon strips on my B&M 250's. I've read a few threads on the internet and it doesn't seem to be to be too complicated.

Anyone have a technical component breakdown sheet laying around.
Thanks,
Jason

Jay, I know the rear bearings and seals are piece of cake, as is the snout bearing.

I may have the literature you seek. Ill dig thru some stuff tomorrow.

Are you finally gonna bolt those babies on??? :santa:

Maybe I'll just pack up some booze and head down to Chicago and see if they'll refresh themselves... lol

It might be cheaper to just send them out to california. We like to drink around here! :drink:

That's a relative term.I've probably bought less for more $$$.

Were you able to find any literature? Do you know what bearing and seal part #'s?
No hurry, just curious.
Thanks

Sorry Rook, cant find the book I had with the breakdown of parts and diagrams.

The bearings themselves, I would buy from a bearing shop. From what I remember, they are nothing more than a very common industrial style bearing. 188 bucks for the bearing kit from jegs is alot. Prob get them from a bearing supply for way less than that.

As far as the blower to manifold mounting. They used an o ring setup on some, and some just a paper gasket. I can tell ya, forget the o ring setup. It flat out leaks. B&M actually had a bulletin on them, to basically go back to the regular gasket. The best gaskets I found are these from RBS superchargers. Good price and they are thick, and dont leak. The B&M 4 bolt mounting setup is not the best, compared to like a GMC blower.

They also have the carb plate gasket, and much cheaper too.

I see they also now have a bearing AND seal kit for them as well.

Lol, I'm sorry I can also use Google. I just thought you might have had the part#'s handy. RBS give you the bearing #'s on their site. Looks like SKF or Timken are about $6ea. I thought there might be some seal inside the ends. I have the intake and carb gaskets already. And I've already been warned to sealant, gasket sealant the intake and blower together. And that the Orings stuck... Literally!

Thanks once again,
Jason

And so it begins...:)
