Vacuum motor repair options?

#1

Post by 428cougarguy » 10 Sep 2019, 21:48

I need a working 1969-1970 headlight actuation vacuum motor. Is critter creek the only option?
Sorry but I just can't afford $685+shipping. :shock: I have bought entire parts cars for less.
I have several core actuators, but none seem to be able to pull in both directions.
Thanks, Scott Taylor

Yeah, for $700 I can put a LOT of man-hours and materials into figuring out how to restore one. Then I can pocket the shipping money I saved >.>
I have a few trashed ones as well that I've thought of tearing apart and trying to rebuild. I've put quite a bit of thought into it, but I just haven't put any time into actually doing it. Hmm... maybe a good side business opportunity :think:

Seriously though, it's metal and rubber. How difficult can it be to fix one if you really put your mind to it? Last I heard, WCCC is making the upper seal and accordian boot. So all you need to do is gently pry one open. Find a suitable rubber material to replace the inner diaphragm. Repair / replace said diaphragm (including remounting the shaft and associated components). Gently pinch it all back together.

And if you have it apart and broken into the basic pieces, why not send the metal cannister halves to the plater and have them redo the original "olive drab" plating instead of using spray paint on it. Or order the materials and plate it yourself, if you're so inclined.

I think the hardest part will be opening the pinch seal without distorting the metal too much, and then pinching it closed again and making it look presentable.

If your center diaphragm is good John's will rebuild it. Here is a link on how to check it. Won't help you out if it sucks air in both directions. His rebuilt won't include replacing the center diaphragm.

I wouldn’t really call that rebuilding. $120 gets you a new seal, and a new boot. Not very good value.

Just buy the Corvette seal kit. Enlarge the holes and install. Easy.

Is that actually olive drab plated? Or is it just painted? I thought Critter Creek painted theirs.

Looks like zinc dichromate - not even close to olive drab

Typically olive drab was used for clips and retainers and not for bolts or nuts

I have several used ones here that pass the test that Brian linked to in post #3. On some of them the accordion seal looks good too.
