New Member in Manassas - CJ7 Owner

Hey Everyone-

I am new to this forum/group. Looking forward to getting some info on stuff and maybe attending a gathering here and there. I own a 1979 CJ7 304. It is lifted, fiberglass body, totally reworked engine and lots of work was done by the previous owner.

Here is a pic.

nice looking CJ, welcome to the site!

[michanecash]

Thanks.

Right of the bat, I wonder if someone could help me. I need to replace the breather on the top of my Dana 20 TC, but I cannot find that part anywhere. I plan on attending the March 20th gathering at the junk yard. Hopefully one will be there. Does anyone know where I can get that piece. On the Novak page its item #36.

I have a pretty good leak and it looks like for some reason fluid is getting pushed out the breather. It may be a seal in the yoke as well, but it is hard to tell exactly.

Welcome!!! I have a CJ like lots of these guys. I just had the t-case out of mine (79') and I don't have a breather. Have what looks like a riser type vent.

Same thing on the tranny from what I can tell. Not sure if that is how it's supposed to be or not.

But I can't find a place that has a screw in spot for a hose fitting.

Beautiful CJ. Remind me to never park my pile next to your Jeep!!!

I cant take responsibility for most of it, but I am trying my best to maintain it. My Uncle - in - law had it restored and probably put $15000 in it and then parked it for a couple years. I heard he was selling it and he sold it to me for $5000.

I was actually able to find the part. This is from a Dana 20 Bronco TC, but should work.

Welcome to the site!!

Welcome, nice looking rig.

[H2_RECOVERY]

Hey welcome!

are you running and Automatic trans or a manual trans? If your running an automatic transmission, then the front seal on the transfer cas input shaft is leaking and allowing the transmission to fill the transfer case in turn it will blow out of the vent.

Its a manual. T150 with a Dana 20. They share some of their fluid, so when the Dana 20 looses fluid it lowers the level inside the tranny.

Yep. I'd like to put vents with tubes on mine, did not realize they were threaded in. Maybe mine are held by mud. I know what I'm changing soon.....:tinysmile_fatgrin_t Time for proper vent lines.

[Pacifier]

You may have to do what I did with the ZUK, it also had one of those weird breathers. I removed the cap, filed it down and installed a real breather tube all the way up to the hood.

This method seems to be the consensus for replacing stock breathers. I just have to figure out how to attach it. I suppose I can modify the breather thats in there to attach the tube. Maybe I will give that a try this weekend. Thanks for the pic. Do you just leave it open, pointing up in the engine compartment?

Are those vise grips a permanent part or is that just something you were working on?

Well if its not broke...

You are having issues with your TCase though right?

[MudyCJ]

Its a manual. T150 with a Dana 20. They share some of their fluid, so when the Dana 20 looses fluid it lowers the level inside the tranny.

They are not suppose to share the same fluid. Same as Mike noted with a auto trans, their is a seal that separates them. If the seal was not installed or put on backwards then it will allow fluid to pass to the other and has the potential for the xfer to overfill out this vent tube and even blow out the seal.

Also what fluid type are you running?

Oh and welcome to the club, that is one clean CJ.

Thanks a lot! I am having fun with it.

I will have to look at my repair manual, but I was pretty sure that it indicated that both share fluid. I'll look again tonight.

I mean if thats the case, it would explain the leak. I did not put it back together and honestly am a little skeptical of the mechanical abilities of the person who did.

I live in a townhouse w/no garage so I wasn't able to try that job on my own.

When I took the Jeep to the shop to get worked on, it was there for syncros and when I got it back it was leaking badly. The shop has since closed down so no going back.

[michanecash]

What if I just capped it off. Would it damage anything inside?

I think it may be best to replace the vent like you had planned, I don't think if designed to vent it should be blocked.

On mine, I'd like to pull those vents, and install some brass barbed hose fittings and raise the vents with tubing like on the axles. Get them up good and high where no water can get in.

I wonder if it will still push fluid out though...

Thanks. Nothing like the smell of oil fuel and exhaust. All of which are plentiful in a CJ and I love it.

Where in Centreville are you? I grew up there.

[blthomas]

Have you determined why fluid is coming back up? Mine might weep a little, but it doesn't push alot back up.

What out for Nik, Zee German will come. :tinysmile_aha_t: :tinysmile_kiss_t: :tinysmile_fatgrin_t

"Of interesting note, the T150 transmission was the subject of a recall in the late 1970's, for its rear seal being installed backwards. This seal should face spring-side towards the front of the transmission."
http://www.novak-adapt.com/knowledge/t150.htm

If it was me, I would make sure that both the T150 and D20 are level with 80W-90 (Dino only, not synthetic). Pull the cap off the top of the breather like Diego did on his axle breather tube and run a hose off it and run it up somewhere along your firewall.

Break clean the shit out of it to remove the mess of leaking and check for wetness and fluid level at your next oil change. From that you should know if you have bad seal.

Thanks. Thats my job this Saturday. We will see if that does it.

[blthomas]

Good info there Jeff.

[michanecash]

So I looked in the Haynes Manual last night. It doesnt directly say that they share fluid, but it does imply it.

It says that when draining the Transmission, do not rely on it FULLY draining the transfer case. You should remove the drain plug on the transfer case as well to get all of the fluid out.

That leads me to believe that they do share fluid.

I did find this post on a different forum and he seem to have the same problem.

http://schohariecountyjeepclub.com/forum/index.php?topic=152.0

I have a lot of car knowledge, but not a lot of experience with 4WD parts. I would like to take the TC off to look at the seal. I think all I should have to do is drop the shaft and then unbolt the transfer case....

Are there any things I should watch out for/know?

[blthomas]

I just pulled mine. Pull the driveshafts, unbolt the shift knob, then I loosened the linkage to let it come down through the floor easier.

4 bolts on back, 3 are visible, on is kind of on top of the t-case, hard to see. I bolt is on the front, through a flange in the transmission. To the right of the front yoke maybe 3 inches.

5 bolts total.

If the bolts holding the skid to the frame aren't rusted, I'd seriously consider dropping it after you supported the tranny with a jack or something and you'd have to unbolt the crossmember from the skid to get the skid down.

With everything mounted to the skid, it's a PITA to shove everything back and forth.

I got mine out without pulling the skid, but my bolts are rusted/bent going into the frame and I didn't want to complicate things by breaking one.

Cool. So I have to let the whole shifting assembly drop down with the transfer case?

I have taken the skid pan off before and they are a pain in the ass to get back on.

I couldn't figure out a way to pull it completely off while under there. On mine there was not enough room to pull the bolts out. So I pulled the knob off, then loosened it and let it lay forward.

Yea it looks like a tough job with that skid.

Yeah that skid is a pain in the ass. My father in law and myself took it off looking for the leak a while ago and it is hard as shit to get back into place. For some reason the tranny wasnt sitting right after we got it reinstalled and it kept popping out of gear. IT SUCKED

how do you post in the live chat. I dont see a script area to type into.

How long of a job do you think it is to switch that seal?

Which gasket is it?

If yours is a 7 and mines a 8, that makes mine the last REAL Jeep, yours is to short to be a real Jeep anyway. Just ask Truck bet he agrees.

[blthomas]

All of ya are wrong. A 10 was the last CJ if we are going by the numbers!!! :p

Are those the ones where only sold overseas? or are you talking about the tugs for airplanes?

[blthomas]

The tugs. I think the drivetrain from one and made back into 4wd would be a neat swap. I thought the tugs had Nissan diesel engines.....but I may be wrong.

Found this pick, I seen another around out on the interweb, not sure that one counts its got SQUARE headlights ewww, real CJs dont have square headlights

[blthomas]

Pretty cool. I guess with a axle swap and maybe a longer tail (thought they were short) it would make a good wheeler.

[Scrambler84]

they are 88 inch wheel base to start and only 2wd locked in low for towing lots of mods to make it usable really
