Hydraulic Clutch

Trying to put hydraulic clutch into 66' CJ-5. I have the original Buick V6 and 70's D30 with disc brakes, along with the master cylinder. I have searched the Novak website and other sites for ideas, but as usual there is no bolt in kit for this project.

I was going to order a Wilwood single swinging pedal assembly and clutch master cylinder both the same size bore, and then a pull type slave cylinder. I am going to fabricate a bracket to mount the slave cylinder to the tranny.

There are two things that I am not sure of (maybe more):
1) The pedal assembly states taht it is a 7:1 ratio, will this affect my setup?
2) I read alot about the release arm ratio on Novak's site, can I use my existing clutch release arm with this setup?

If there is an easy way to do this please let me know.

Thanks

I did see that at Novak, but the release arm on the Buick V6 bellhousing is not long enough. The bracket for that kit sticks out 3.5" past the bellhousing, and the release arm on the Buick V6 bellhousing does not stick out past the bellhousing.

I thought if I made a bracket for the Transmission that I could use a pull type slave cylinder and use the existing release arm.

It sounds like I might just have to give it a whirl and see what happens.

 

In changing my clutch to hydraulic, I have a push type slave from a 1980 CJ5 renegade but it looks like the Chevy V8 bellhousing sticks out too far to use it. From what vehicle would I get a pull type slave cyl.?

I don't know much about hydraulic clutches but I would try after market - Wilwood (spelling?).

 

Here's a pic of my setup using a Wilwood slave and a bracket I fabricated. There is also a pic of a brace that I fabbed about a year later to re-inforce the bracket. The brace bolts to the T case and the slave braket and stiffens the bracket up real well. I may still have paper templates of them if you are interested. Send me a PM. I can mail them to you.

 

Just realized the templates won't work for you unless you are using a T18 tranny. But you get the idea. I had a welder bend the 90 in the bracket after I cut it out. The buggered welds are mine. LOL

 

The pull type slave that i found was from Wilwood p/n 260-1333 you can get it from JEGS p/n 950-260-1333.

 

I am running the hydraulic system from willwood that you are talking about. The biggest thing is to measure the travel before you remove the mechanical linkage to make sure the slave will move the release arm far enough. It should. I have no problem with their pedal system, running mopar 360 and manual tranny out of a 3/4 ton. Try speedway motors to order the parts from. http://www.speedwaymotors.com/ That is where I got mine. All in all the setup works great. No binding whatsoever.

 

I am researching this application. A friend who is a roundy round guy said these are simple to setup and adapt easy. He said he use to install these in rockcrawlers but not I wonder if it will work on the GM BOP bell. I'm looking for one on ebaY so I can experiment and mock up.

check out Advance Adaptors kit. Hyd. clutch and swing pedals.

 

I used the Novak kit in my CJ and it works fine. I thought the kit came with a new fork, but you can also order one from any GM dealer. The slave cylinder is a 3/4" bore and the master I am using is from a 90s Wrangler also with a 3/4" bore. I could have fabbed a bracket, and found a slave cylinder to work, but I think the time to fab something & the research Novak did assembling their kit made it worth buying their kit. Just my $.02. It is an easy conversion.

 

Hansh, do you have the part numbers? I am looking to do this to my 71 with the v6 and t14

 

I'll have to look deep to see what I can find. I did it a couple years back. Novak may have the part numbers for some of the parts. I'll take a look this weekend.

 

Here is the braket I Made. If I would have known about Novak's braket I would have bought one.

what's the slave cylinder from? Good job btw

 

Good job. Making any more?

 

I don't know. I bought it at a local 4X4 shop. I don't know who makes it. There is no brand name on it. Sorry.

 

Also trying to do this conversion to a Buick 225 and T-18. Using the stock clutch fork. I fabricated a bracket similar to the one Posimoto showed in post #6 above and am also using the Wilwood pull-type slave.

I have a question about it's operation. The slave cylinder obviously wants to move straight forward and backward, but the clutch fork moves in an arc. Seems to me that it is going to bind up. Has anyone else experienced this? What was your solution? I'm thinking if I leave a little slack on the acorn-looking fitting at the fork, it will allow enough free movement.

 

Here's the pics of what I've got, please note bleeder is upside down and would need to get flipped for you application:
