Mustang 5.0 into a CJ7 questions

A friend has an 85 CJ7 with a mustang 5.0 in it and a T-5 tranny on.

The clutch setup is a pull on the clutch fork, not a push like a CJ clutch.

The bell housing, clutch and tranny 'appear' to be the borg warner Mustang T-5 because there is no internal pivot for the clutch fork in the bell housing.

Someone has used a brake cable to sort of give him a cable actuated clutch, but it doesn't work for shit and the cable keeps snapping.

Has anyone done this type of conversion and if so how did you make the clutch work?

Mustang pedal? Hydraulic? Cable?

Thanks,

Mike

Do you think something like that will work with the CJ manual clutch pedal?

He would need some type of Jeep master cylinder and the pushrod for it right?

Maybe a YJ master?

Then would a Jeep master have enough flow to make that monster slave move far enough?

I checked out prices for the hydraulic kits and WOW! Almost $500.00 US which is way over $800.00 by the time it gets here...

The cable in it now only moves 1/2" at the clutch fork with full travel of the pedal and 5th will start the new clutch smoking, so it isn't releasing enough for the pressure plate to clamp down and is barley letting him get into gear as well.

He did buy the CJ7 cheap with a smoked out clutch and broken cable...

We checked out some junkers for hydraulic parts, could make a YJ master fit in easy then I suddenly clicked in that he now only has 1/2" of movement, I wonder what my 'push' setup on my stock CJ mechanical linkage has.

Well, you know, I have slightly over 1" of 'push' with 1"+ of free play at the top of the pedal.

Hmmm.....

So I am thinking, if we put the stock linkage back in his and I cut the bar off that holds the rod to the clutch fork and put it on top of the arm from the firewall to the bell housing instead of it being on the bottom, that will give me at least 1" of 'pull'.

Then a piece of threaded rod would only need a 90 deg bend at the lever and an inch or so of downward Z shape to have a straight pull on the clutch fork. I could gusset it easy so the Z shape holds. I have a small wire feed 'MIG'.

Or does anyone know if a slight upward pull on the fork will harm the throw out bearing?

Then he is back with Jeep parts and solid mechanical linkage like he 'should' be in my mind.

Sound ok?

Does anyone have a clue what the travel on the clutch fork for a Mustang T5 'should' be?

I was told that the Mustang T5 should clutch fork have 7 lb pull on it when the clutch pedal was released to be set up right? This means the throw out bearing is 'pre-loaded', not floating free like the Jeep T5 clutch.

I could make a longer or shorter arm if needed.

Any opinions?

Thanks,

Mike

Guys I worked with at a Mack garage in Hagerstown, MD swore up and down that a Mack clutch cable was good enough for any vehicle. I don't like clutch cables myself, but the truly annoying thing about these guys was that they had been putting Mack clutch cables in everything for so long that they had actually gotten good at it.

Another idea that I think I saw in an Advance Adapters catalog is to use a bicycle chain and a sprocket to convert a push type linkage to pull type.

I like hydraulics myself, but you have to get the lever arm right no matter what you do.

I think I can just convert a stock CJ7 mechanical linkage to a puller for really cheap and then no cables to break or wear or stretch, etc...

You know, the 'KISS' principal...

Got a young rookie owner scared half silly of this aborted Mustang 5.0 project he bought....

He has good potential and likes it enough to either make the clutch work or sell it off like the last guy did and look for another CJ. Actually he wants to look first, then sell if we can't make it behave.

I am off work from a car accident and helping him out with moral support and a bit of know how to point him at what bolt to turn or what part he needs is a 'great' way to pass the time. :-))
