Mamiya 90mm rb lens repair manual?

[brent.bousquet]

I got a lot of old rb lenses and some of them are in different states of disassembly. I think the person was going to try to make a good one using the parts but now I'm not sure exactly how they go back together any ideas on a manual for at least the 90mm I cant find one online.

I think I might have one buried around here someplace Brent. I'll take a look, if I can find it I'll scan it for you. If its the one I'm thinking of however it didn't look overly useful. I think it amounted to an exploded view and a parts list. Could however be enough to show you how things screw back together.

Back soon...

Thanks for looking anything is better than what I have which is a pile of parts. haha Luckily there was a mostly complete one but I cant figure out how the back goes together.

Brent, I found some information for you. I have scans of the exploded views for the 50, 65, 90, 127, 180, 250, and 360mm lenses. I also have a scan of the Pro S repair manual which has some lens detail near the end. All together the two .pdf documents will be about 8.5mb. PM me your email address and I'll get them off to you.

90's are pretty cheap. If nothing else, buy one, take it apart and take pics of every step. You should be able to ID every screw and so on. Then you can sell one. And you'll need a spanner wrench either way.

Apugger Ron Paul is very knowledgable about servicing RB lenses, too.

Www.Edsawyer.com/lenstests/ is where I have a bunch of mamiya repair info posted, mostly RZ but it would be similar to RB as well.
