Title: Hydraulic clutch conversion on a 1981 jeep cj7 with 4.2 L and a T5 trans
Post by: bdron on March 11, 2015, 05:24:14 PM

I am wanting to convert my clutch to a hydraulic system and I wonder if anyone else on here has done it and what all I would need to do the change over on my 1981 cj7. I do have a master clutch cylinder and pedals from a 1987 yj if that helps me. Please let me know if you could tell me if there is a way that I can do it.

That will take some research. Easiest thing to do would be to call Advance, and or Novak and ask if they have done it.

Advance does a nice slave kit used for most universal installs.

From there you would need to source, or build the bracket to mount the slave.


Found it. I've used this one a few times. Once on my 4500 swap, and once on a ford T18 into a CJ behind a Golan Stroker.

Oh, and here is a good thread on it from Jeep Forum. Guys are using the iron duke 4 cylinder stuff and seem to be having success with it. Essentially the same thing I linked, but should be cheaper through local part stores knowing the application to ask for.

Call local and see what they give you for prices.

The steel line you can build at Mopac for cheap.

Amc eagles used a 4.2l and T5 with a hydraulic clutch. Napa still lists a slave  cylinder for around $30.
