New Jeep, New problems!

Hey everyone. I've been lurking here for the past few weeks since I bought my new (old) CJ5. It's a 1967 with a running 305, but obviously is going to need some work. First thing's first - here are the pictures:







I've already done most of the wiring...and now I'm on to the other big problems: brakes, transfer case, cracked windshield, etc. I'm hoping to make this a weekend toy - not for rough offroading, but just for fun.

Now, the current problem is this:

Any ideas? It only really does it when it's driving in gear - not while coasting or with the clutch in. I'm guessing something in the transmission or transfer case. I've got a friend that going to help me drop the transmission and transfer case on Thursday, so we'll see what happens.

Thanks for the help, and I'm looking forward to sticking around!

 

Nice Jeep! Looks like it'll be just right for your intended use(s).

"Now, the current problem is this: _____ " A Jeep with no problems? WOW! Just yanking your chain.

 

is that a t90 behind a v8? its been my experience t90's an v8's don't agree.

 

Very clean jeep to start with for a play toy, nice. I'm not seeing any rust to speak of at all?? The jeep must have spent much of it's life in North Texas. Already has a V8, again...nice.

Good luck with the noise, I'm betting it is the idler shaft in the t-case. If so, from what I have heard / read, etc, the Novak rebuild kit is first rate.

 

Current problem is what? No info showing on that

 

Put the T-case in neutral and run the tranny thru the gears and see if you still get the noise.

 

Thanks everybody, I'll try all of those out ideas. For those that weren't able to see the video I posted, I put a link to view it in the post. On a side note, popping the top of the transmission is my next thing - it goes into R, 1st, and 2nd, but won't go into third. Maybe somethings out of line there. I don't have a lot of experience with cars, but I'm pretty much a handyman. I'm guessing it is the t90 transmission, since it has the original dana 18 transfer case, but I'm just a rookie here. Also, I can't get the transfer case to shift out of low gear. It will do both 4 and 2 wheel low, and neutral, but I can't get it in high. I definitely have myself a project.

In terms of rust, it doesn't appear to have much at all. The guy I bought it from painted the whole thing with black rustoleum, so I'm probably going to be sanding down the rough patches and priming the whole thing, and eventually painting it...maybe just a rattle can job for now. The frame looks great too - but does have two small cracks at the very back where it meets the bumper. Looks like someone tried to pull something too hard, but the rest looks solid, and I've already spent a lot of time under it.

 

....just tried it with the t-case in neutral. There is some chatter noise from the transmission, but the scraping noise it gone. Guess that means it's in the transfer case.

 

That is an ugly sound.
My next step would be to pull the transfer case lower cover off, check out what's going on in there.
Check out the sheet metal cover too, something might be rubbing aginst the gears.

 

Ok. Video link shows up now. Basically what everyone else said.

 

Not really true. It depends most on your use of the right foot and common sense. Big tires and burnouts will eat one in a hurry but it should otherwise live just fine behind a 305. The 305 will actually make a good motor for a CJ-long stroke for the displacement. Appears to be a nice 5 with a lot of potential.

 

Ok, so instead of looking at the transfer case, I went ahead and pulled the top off the transmission to see what was going on with being unable to shift into third gear. Working from the top side is much easier than being underneath... After I got over the initial shock of seeing it full of a watery muddy looking goop, and draining it, I started to look for problems. That was when I found this:






Apparently the burrs that have ended up on the top of the well worn blocking ring are keeping it from shifting - and so I'm assuming that this means I get to do a full rebuild? Woohoo.... It is a T-90 - I discovered that as I was scraping the grime off of it. All the other gears work, although I did have a poppet ball shoot out at me, and I'm not sure if the spring came too or not. I do have the Hayes manual, but I'll probably be asking everyone for advice - especially when it comes to removing them (going to have to wait two weeks). Thanks in advance!

 

Just rebuild my t90 and d18 easy enough Novak is a good place http://www.novak-adapt.com/knowledge/t90_rebuild.htm
also http://www.willystech.com/wt/T90RebuildGuide/T90rebuild.htm helps . good luck nice jeep

 

Thanks! I'll start there!

 

Ok, today was a fun one. Nothing like working outside in 104 degree Texas heat. I pulled the transmission and the transfer case today, and started taking apart the transmission. Here it is right after pulling it:



My dog was rather helpful in the process of course...



The most difficult part for me was separating the transmission from the transfer case. I removed all the bolts that held them together, and then tackled the back of the transfer case where the main drive connects. After I took off the nut that holds the main drive, it took a little "persuasion" to get them apart, but we finally got there.

Here's where I ended the day:




My blocking rings are supposed to come in on Monday. I'm probably just going to order the whole small parts kit and replace a few other things while I'm at it. The gears look pretty good, other than the third gear syncro blocking ring.

A couple of things I'm wondering about though. Before I even had the transmission apart, I noticed that I could really jiggle the main shaft - it had a lot of play. Should it be like that, or are my front bearings shot? Also, I noticed that the throwout bearing doesn't spin in a perfect circle - kind of a side to side spin. Is that shot too?

Also, any recommendations for getting the 40+ years of dirt and junk off of the transfer case and transmission....other than a screwdriver? Any soaking methods, etc?

I'm moving on to the brakes after I get this project done to replace some leaky cylinders, and probably brake pads. The rear hubs seem to be attached to the drums, so that looks like it's going to be a hoot and a holler to get off. O'Reilly doesn't have a hub puller to rent. Looks like I'll try Autozone.

Thanks for the help and following along!

 

For cleaning the outside use a scraper and get off all the loose stuff. Then soak them in something like Castrol Super Clean, Greased Lightning, or whatever nasty stuff you have available. Some use oven cleaner which works great but can be toxic/nasty to work with. After letting it soak in, scrape again. Keep doing this until you get it reasonably clean. After you get it apart clean it again. it takes some work but the results are well worth it, especially when you put it together and paint it and it looks so nice....
