fj40 3-speed vacuum case

[megolfer]

I have a 3-speed case that is vacuum and I would like to convert it over to linkage. I also have a linkage case, can I take the parts of the linkage case and put them on the the vacuum case. Will everything work right.

Thanks

Yes.

I second SpaceGhost on that, it's really easy :G

Are you running a three speed or did you swap trannies? If you did, it won't be a straight bolt up deal for the linkage. Ran into the same thing when I swapped to a four speed.

has anyone kept the vacuum linkage?
i have a 76 without the lever on the dash. i am trying to find an electrical/mechanical switch i can install.
any suggestions? ???

buy a solenoid from MSC Direct or some place like that...

hey like i said on pirate...make sure you pop out that lock ring and swap bearings...the one in the three speed is brand spankin new...

I still have the vacuum actuated t-case. It hasn't caused me any problems yet, and since I don't get to wheel it all that often, I haven't made the effort to change it. That being said- if someone were to offer me the proper hardware to convert it to manual linkage- I might be persuaded... But until then- it's vacuum all the way!

i found an electrically activated pnuematic switch from a 95 4runner that will actuate the 2/4 lever similiar to the way an ARB works. i will put a momentary rocker switch with an indicator light that tells me when its in 4 wheel drive. should be cool if it works.

not sure about the failure part ???. i am doing a 420 swap and got a used 3 speed t-case that had the vacuum lever.

Why is the mechanical linkage better than the vacume?

 

[CruisinGA]

Its less apt to failure, no tubes and such to wear out with time, just plain simpler. Always remember to K.I.S.S. (Keep it simple, stupid)

I (or more likely the PO) got water in my vacuum mechanism, and it froze everything up when it got cold and I needed it. So that is one reason mechanical is better.

Oh yeah I remember that thread on SOR, that was a bugger for a while!
