Here is a MPS that doesn't hold a vacuum. Looks like a rebuilt unit too.

After drilling out the rivets, the MPS comes apart

covers with and without the epoxy

After heating the epoxy with a heat gun, it is scraped off and the plug is screwed into the cover. The threads are carefully cleaned so the plug screws back in.

A good diaphram without any cracks.

The diaphram is installed with a light coating of sealant

The spacer installed

nice shots, thanks. can we put this in classics?

I need a couple of "not-yet visible cracks" diaphragms.

Excellent photos.

What kind of digital camera are you using?

So why wasn't that MPS holding a vacuum? Are you putting back the same diaphram?

Looks like the paper gasket and the big o ring weren't sealing. Trying to finish that MPS tonight as I read all the funny posts.

Oh, the shots were taken with a Nikon 5000 without a flash. DaveP, I wish I had a stash of good diaphram!!! I have two or three left.

Read this funny man: Where is the MPS you still owe me?

If all goes well with my Kit Carlson, you guys can take yer MPS's and......

What MPS?
