4wd Vacuum diaphram fix

[iapexl8r]

Hey everybody i have a 1976 Jeep cherokee chief . And I think my 4wd actuating diaphram is shot. I hook my vac pump to either side and cannot make vacuum.

I cannot seem to find this part. Is there a modification or a fix for this. Any help would be greatly appreciated.

Been several years since I had to deal with a QT but @ one time mile marker was still making them.
Might try giving them a phone call?

Used to be someone on eBay selling them, or used is obviously an option as well.

I had to search one down last year and bought one of the NOS ones on ebay. Dude was charging $80/each but I needed it. When I bought it, he said he only had one more after me. I do not know of anyone else making them.

The want ad you posted is probably your best bet. I am sure someone has one laying around.

At one time Rocklaurence was entertaining the idea of making a manual pull handle but I don't think anything came of that.
