CJ clutch cylinder?

[Cecil14]

Anybody know if a clutch master cylinder from a CJ will work on my J-10? I think the pedals are pretty close...?

I can't get the bellcrank setup to work so I'm thinking hydro is gonna have to be the way I go.

Thanks,

Most new motorcycles and many foreign cars use hydraulic clutches if the Jeep one won't work. If you got the master cylinder and slave cylinder it should work great. You already have the clutch pedal installed, right? Hooking the new master cylinder to the pedal linkage may be weird since the linkage moves downward toward the bell crank. Had a hydraulic clutch on my 240Z, but I think the linkage moved horizontally. But the slave cylinder should be easy to install on the bellhousing.

I have been thinking about this a lot lately. I think I read or heard that some early 80's CJ's had hydro clutches and the slave cylender bolted to the bellhousing where the old bellcrank used to. So if that is true then that would be the easy part. the hard part would be mounting the master cylender. My YJ has a hydro clutch (it is a internal one though) and the master cylender mounts right next to the brake master cylender/booster. the booster/cylender are bolted to a spacer and the booster is made to allow clearance for the clutch m/s (i.e.--tight fit) So the hard part will be mounting the m/s since the FSJ one is big around and close the the firewall. attaching it the the pedal wont be too hard. it's just simple math and measureing twice, drill once type of thing. All you would need to do is measure how far the m/s has to travel, measure how far out the rod will stick out past the firewall and find a point on the pedal where when it is all the way up the m/s rod is all the way out and when it is depresed the m/s rod is pressed in how far it need to be. Now drill and mount it in that location, moving it to enough to the side to clear the brake booster but leave it as close as you can. Now just weld or mount in some way wery well another rod to connect the pedal to the m/s. Dont know how long it would need to be but should be able to brace it to hold good enough. Also, if you had hydro boost brakes that would make it a little easyer.
Well thats the way I have dreamed it up in my head. I havent really looked for a slave cylender (havent really had time lately) Maby if we put our heads together we could figure it out.

The slave is easy, I can use a CJ slave, know that part already. I just need to know if the CJ master will work with my pedal. There's already linkage on the master to go to the pedal and I believe it bolts on where the bellcrank linkage normally goes, just need to know if they will fit together.

Anyone know if an '80s fullsize chevy master would work?

I think any master should work. How about using a mini turnbuckle with heim joints at the master? Then you can control the stroke.

Not shure on the interchangeabilty of the masters. I would say stay with the master made for the slave. The chevy one might push too mutch or not enough fluid for the Jeep slave. As for the mounting part. I think the hard part will be mounting the master. as where it need to be to attach to the pedal is very close to the brake booster. mounting it to the pedal shouldnt be too hard, even if you have to take the pedal out and drill a new hole. I dont think there will be a hole in it that will line up the way it need to be. Though I could be wrong. I dont have a master setting around I can measure and play with.
Just wondering, what year, model, engine/tranny CJ are these parts from? Good luck Jared

Don't have the parts but I was thinking about using some from an '80s CJ. Master/slaves should be the same between 6/8 cylinders. Just gotta find some for real cheap now.
