Vacuum shift actuator replacement?
« on: July 15, 2012, 06:25:32 PM »
Well the Vacuum shift actuator thing on my eagles transferr case does not shift anymore.  I did convert it to shift on the fly (using a hose clamp and removing the vacuum lines on the front axle).
It worked great for a while but now the actuator at the t-case is just stuck, I took it off and it is just not moving anywhere.   

SO... my question is, can I remove the actuator at the front axle and use it at the t-case and use something else to keep the front axle engaged?

I found THIS on summit racing website for jeeps to keep a dana 30 locked in all the time.  SHOULD work just fine for an eagle.   http://www.summitracing.com/parts/POS-1100/?rtype=10

Unless someone knows where to get a new actuator?? or has one I can buy?????

not sure if this would apply in your case, but would this work to keep in engaged all the time?

I would like to get it to work properly so that I can sell the Car.
That Is why I would like to retain the shift ability of the transfer case via the original switch.

Can I somehow remove the vacuum actuator from the front axle assembly and use it on the transfer case???

yeah I just realized before my trans install (attempt) that mine had quit moving/froze up.Happy to see it's available but not at that price,guess I'll stick with manual shifting until I can track down a cheaper replacement.

OMG I bought that exact part from that site about 4 or 5 years ago for 50 dollars talk about a mark up.
I Don't know why. But everybody's always talking about their STI or That guys EVO, I think I'll stick with my old, but reliable AmC. Did I ever tell you I was Full blooded Eagle?

Your question: Can I somehow remove the vacuum actuator from the front axle assembly and use it on the transfer case???

The actuator on the front axle is different enough, mounting-wise and actuator-shaft-wise, to not be easily adapted to use it on the transfer case.

If any of your local salvage yards have any full-size Jeep Grand Wagoneers that were equipped with Selec-Trac, then they have a shift actuator that you could use.

The TeamGW price is obscene, but they are a specialty company, and can charge whatever they think they'll get from someone doing a perfection-restoration on a full size Jeep. The prices for FSJs in good shape are obscene, too, at least from the two FSJ-only dealers here in TX. Its a shame they have a role in the inflated prices of parts like the one you need.

The auction sites might have what you need, try searching for Grand Wagonner transfer case vacuum shifter. There are enough of them out there that someone is bound to be selling that part ,if you can't find it by searching for a listing specific to Eagle.
