clutch/brake linkage question

Howdy all,
I decided to tackle some of the work on Morgan's (knownothinjeeper) Cj. He's in school (boarding) so doesn't have a lot of free time to help me work on his project. I know he needs to learn, but at this rate he could be an old man before the jeeps roadworthy!
Anyway, when you depress either the clutch or the brake pedal both of them move. I ordered new pivot tube, shaft, seals, and spring. Got it all loose today, but have new parts that don't match up with old, and I don't really see where there was a lot of wear on the shaft anyway. I need to clean all the gunk off to see if it was just binding on years of dirt. Does anyone have a photo or parts diagram showing how the whole pedal mount/pivot goes together? There may have been parts already missing for all I know.
Thanks!!
Megan

 

Wow, they both depress simultaneously?

Might be possible to clean up and grease the existing parts especially if you don't notice too much wear, and since the new parts don't jive. I'll see what I can do re: pic. Perhaps it'd be a good idea to snap a pic of what you have and perhaps we can go from there. ?

 

Ooops, I should have said that they both depress too some degree! Sure would be a bummer if they both went all the way down together. We'd never get anywhere! I'll try to snap some pics tomorrow. I've got a feeling I'm having a senior moment with it. The clutch tube that I ordered looks right, but I also got another tube that doesn't match up. Also spring and felt washers that don't look familiar. I'll get pics up, you'll probably all get a laugh at my expense.
Thanks,
Megan

 

mine did the same thing when i first went at everything... i just cleaned it up, sanded with an emory cloth and put some new grease on everything. they still moved a little bit, but once i put the springs back on them they stopped doing it. it might just need a little cleaning, but new parts can't really hurt the situation.

i can't be a help on the pics though, i never stopped long enough to actually record what i did...

 

I’ve noticed a strange occurrence with a couple of my older jeeps (a 1953 and a 1956) with the brake and clutch. For example as you come up to a stop sign and you push the clutch to the floorboard and have your other foot pressing on the brake to stop, then to get moving again, you release the clutch while holding pressure on the brake, the clutch will stay down. Only when you let off of the brake then clutch will let out.

Sometimes I have wondered if this maybe designed to operate this way.


Has anyone else noticed this phenomenon?

 

The odd tube you have sounds like the rear clutch linkage tube. Does it have ears welded onto it ?

 

Yep, two ears on it. I really need to get it up on jack stands so I can get a better look around under there. (Where's that lift I asked for for Christmas? :? ) I hadn't really had a lot of time to spend on this lately, but figured I better make some time, as knownothin is getting fired up to have it on the road! 17 years old and wants to actually DRIVE his jeep? Go figure! R) I'll get pics today and post. As always, Thanks for the help!

Yep thats what I thought . In case you dont know the rod is mounted a little farther back between the inside of the frame and the tranfer case. If you got a kit it shoud have came with new replacment pivot balls for the tube.I would go ahead and replace them if I was you replacing the tube they only add 10 minutes to the job at most .

 

OkeyDoke,
Got it all apart and clean. The shaft was scarred up, but I honed the tube a bit and installed new shaft. Replaced grease fittings as well. Ran a hone lightly through both brake and clutch pedals to make sure everything moved smoothly. Lynn, I had a job getting the old key out of the keyway, I'll try to remember to put the bugger back! I've still got unidentified new parts. I know what I think I ordered, but they came with no part numbers attached so I can't tell if I ordered the wrong stuff or what. I'm attaching a pic of parts. The ones on the left are the old and new shaft. The ones on the right are unidentified. Could it be a brake/clutch tube for a different vehicle? The other parts look like draglink to bell crank & draglink to steering box, but that doesn't make sense as those aren't removable. I knew better than to order parts when I wouldn't be able to work on the thing for awhile!
Thanks,
Megan

Doggone, I've done it again. My computer has me logged in as knownothinjeeper! It's actually MPH.

 

Before I put this back together, What's supposed to seal up the hole in the floor where the brake pedal goes through. Is it the same as the clutch? The clutch has a large felt washer, metal washer, and spring to keep it tight to the floor. These are pictures of both. Oh, and many thanks to whoever reccomended some time back that I remove the fender before starting any work on the CJ. I dallied a bit on the advice...but when I finally took it off, it was like coming out of a cave! Everything is much easier to get to! Cheers for the suggestion!

Let me try that again!

 

here''s th clutch pedal with felt, washer, and spring.

 

What an excellent idea...but what's to keep my beer from falling out the bottom now? Oh yeah, just drink faster!

 

Those parts on the right are the clutch pivot rod & pivot balls, pretty much exactly what Hawk62 said:

The pivot balls fit inside the ends of that rod/shaft, with one ball anchored to the frame, the other on the x-fer case. Once you get the clutch pedals installed and go to hook up the clutch linkage, trace the linkage back and you'll see the bellcrank/pivot rod.

 

Thanks Hawk and Hippo. I guess I just didn't look around enough while I was under there. What do you expect, I drive a jeepster commando automatic! R) I'll crawl back under in a bit.
I sure appreciate the help and knowledge!

 

Well, who knew that jeep used both mechanical and cable clutch linkage! At least I don't feel quite as dumb as I did earlier. Now I've got parts I don't need. If anybody needs the clutch pivot and associated parts, let me know! Got it all re-installed, but need to pick up a washer to get rid of some side to side slop in the brake. Thanks for the help!

MPH: Krage has a "kit" for both the clutch and brake pedal holes. It comes with new springs and big 3/16" thich washers, costs about 12 bucks. Beer cozy works fine, but the heat will soon kill it.
