, here is under the roll bar mounts in the front. The rears look just like the front. They have little rust. I took a screw driver and dug around and no holes or flakes of rust came about so once I decide on what I want to do on stripping the paint, we will see how well the area holds up.
@Axhammer , to answer your question about the chemical stripping, it's basically like hot tanking a engine. The place I take it to doesn't have a post dip to prevent rust but they keep it inside until it's picked up. They suggest priming it as soon as possible to prevent flash rust but I've had parts in the garage for over 6 months with no primer and no rust has appeared.
If I go the sandblast route, a company is going to do it. I'd kill my air compressor doing that lol

Nice tub. Itís hard to believe it isnít rusted under the roll bar mounts.
I havenít heard of that method you refer to, ďdipping it in a chemicalĒ for stripping paint? If you do dip it to strip it, you better dip it to prime it, so you donít leave any bare metal in any blind, or hard to access areas.
I sandblasted my 1969 Firebird back in the late eighties when I first bought it. That was a lot of work, messy work, but I definitely removed all the paint and rust when I sandblasted it myself. I used a chemical stripper to strip the paint first. Then I sand blasted the metal to get it clean, some refer to as ďwhiteĒ metal. I sandblasted a 1971 Chevy shortbed pickup about five or six years later. I blasted the frame, bed, cab, tailgate & doors. I had access to better equipment when I did that truck, so I didnít have to chemical strip it first, but it was still a lot of work.
There are companies that specialize in this type of work now, and there are different mediaís being used to strip paint as well. For example, walnut shells, soda, plastic, sand, are some of the media I am familiar with, so there are some choices out there, but I guess it depends on what you can find locally, depending on where you live.
I think the most important part of the stripping process is getting a good, high quality primer applied before the bare metal gets a chance to start rusting again. And then, If you pay someone to do it, you have to go over what was stripped and primed for missed rust...thatís the biggest problem with hiring someone else to strip it and prime it. You have to trust they will do it right. You can damage the sheet metal if your equipment has the power, it will warp or collapse it if you arenít careful.
Having said all of that, I will hire someone to do it for me when I pull the tub off my 1985 CJ-7, in the not to distant future. It will get done much faster, saving time and effort on my part. I donít have the energy to do this stuff like I used to.

The tub fits in the garage and I can still get my Ranger in as well, so it will always be covered. If I have to put epoxy primer on it, I can always do that until I pick out a body shop. I'm just unsure if dipping the tub is necessary given that there hardly any rust.
As for paint... That's a huge debate. The original paint is 4C, Ice Blue Poly. I really like the 2D, Deep Night Blue but seeing the tub in 5C, Red Metallic I don't know what I like best. I have original, unused, silver Laredo decals I want to put on it. I just know what would look best. I want 1985 colors but I also want the Laredo decals to look as if the color combo was from the factory. I still have time to figure it out

|Jim1611||Have you checked under the roll bar mounts for rust? I'm not sure what I'd do on the paint. If the place that does the stripping also could dip it to protect the bare metal you'd be way ahead over sandblasting, I think. Sandblasting is allot of work if you do it yourself. I'd tend to want to find a place to do that job for me. Nice tub! What color is the final product going to be?|

Got a tub and a review of Rudy's CJs
Over the memorial day weekend, I took a 2.5 hour drive up to see Rudy's CJs and came back with a tub! I have been waiting for something this nice to come along for over two years. After digging into the tub that came off my Jeep, it was just more cost effective to replace the tub.
This tub came from Arizona and has some sun fade and a couple dents here and there. The best part about it is, there is not a spot of rot on the tub. Maybe a little surface rust here and there but no rotting or rust holes. The pressure washer did quick work getting the bottom and inside cleaned up.
Rudy was extremely nice and showed me what all he does and took me on a tour of his place. He has A LOT of OEM Jeep stuff that is in great shape. He may be a little expensive for some but the quality he has is superior to most aftermarket. He can even ship some parts for those who cant just take a quick trip like I can. There are certainly many people out there with great OEM Jeep parts but if anyone needs a review of Rudys CJ, I would recommend him and I will buy from him again.
I would also like some advice on what to do.. Sandblast or chemically dip to remove the paint. I honestly don't know what would be better

The Koyo Bearings plant is right down road from me. Just so you know, Koyo bought Timken about a decade ago, so more than likely the races and the bearings were all replaced, just probably were made during the transition and had some parts stamped Koyo and some stamped Timken coming together as one final assembly.
...or, someone only changed the bearings, not the bearing races (but that would be a strange thing to do in my opinion)

Yesterday I finally got the transmission buttoned up and ready to be put back in the frame! A few setbacks had it sitting for a week waiting to be put together. After taking it all apart I found that someone changed the bearings but not the bearing races... For example, the bearings were made by Koyo and the bearing race was made by Timken and the Timken races look like they were original. The end play tolerance was way out before at about .05" to .09" so I'm extremely happy I decided to rebuild it. Now on to the transfer case!
|05-06-2020 04:37 PM|
With the main shaft of the transmission being sent to Texas Drivetrain Performance for the bearing repair I went crazy on cleaning... My OCD kicked in and I went overkill.
Really, all I did was take everything to the parts washer and use series of brushes. Tooth brush all the way to a smaller hand scrub brush, a parts washer brush took care of the hard to reach areas. After cleaning I followed it up with air to clean out any settled debris. I decided for future cleaning and identifying any leaks I would spray the aluminum with aluminum colored paint. I know you wont see it but it had over spray on it and it just looked too normal.. after taping off some crucial areas, I LIGHTLY sand blasted it. Avoiding any sealing surfaces! I only blasted the outside case that you see. I got a ton of grief at work for sandblasting aluminum but what do I know? anyways, it looked great. after a etching primer, it got a nice finish.
Next I decided to get some parts in the housing before I lost track of them or got knocked off the work bench. It is truly amazing how well parts go together when everything is clean. I triple checked all the new parts with the old parts to make sure tolerances was acceptable. Yes, I even cleaned the old parts to make sure oils and grease would not effect tolerances...
Everything checked out good if not even better than before. I got the counter shaft assembled as far as I can go until the main shaft arrives this weekend. I have no end play and everything spins as free as it can with assembly lube in the bearings.
If anyone is rebuilding or considering rebuilding the T5 or T4 and having troubles, feel free to ask. I might have an answer!

Upon futher inspection of the transmission.. The main shaft has seen better days where the needle bearings let it ride on the input shaft from the clutch.
My options are to take it to a machine shop and have it welded and machined down and polished or to make a sleeve out of a bearing rated steel and grind and polish down. The T4/5 main shaft is no longer produced for non world class JEEP applications. I've spent 3 days making phone calls and every one has said the only non world class main shaft produced is 14-3/4" long where the Jeep version is 14-1/8". Borg Warner and tremec teamed up at some point and now everything is made by tremec.
This is territory I have not been though yet. Let me know if someone has ever done anything like this!

This weekend I decided its time to clean the leaking oil off the garage floor and figure out the leaking areas of the transmission and transfer case. It was a good move on my part. Found some needle bearings that were in need of service on the input shaft of the T5. The transfer case is getting new bearings and seals since putting new seals is basically the same process as rebuilding. Do it all at one time rather than be sorry later. I'm not going to detail this rebuild just because I think there is enough documentation already out there, especially for the Dana 300. If someone specifically asks me to do it, I don't mind. I need to travel out to my farm to get the parts washer to clean everything so I wont mess with this much this week.
At a first glance it looks really good. Synchros seem to look okay but will be replaced since I have new ones. I don't know what the end play is supped to be on the T5 yet but I thought there was too much end play. Ill refer to the manuals to make sure I correct it.
Everything laid out as the parts come off the shafts to ensure correct assembly.
I only found this one chip in what I assume is the reverse gear The idler/ engagement gear doesn't appear to be chipped so maybe some one opened this up and hit it with a hammer by accident or just really forced it into gear.

Transmission/ T-case questions!
I would like your guy's advice on the transmission and T-case... I have a T-5 five speed and Dana 300. I know its not a tough trans but I don't plan to off road hard core. Just to go on occasional trail rides and typical farm use up and down valleys
When I had the engine out of the frame, I cleaned up the grease covered trans and T-case but never opened them up.. Now that they are looking nice and clean, attached to the motor and inside the frame, the transmission has a leak... I think it could be due to the cleaning or it could have been leaking to begin with (why it was covered in grime). It is leaking between the actual gear box area and the output drive below the shift lever (see picture).
So my plan is to take it apart and just seal up that area... BUT, I have a complete rebuild kit for it. Is it worth it to rebuild the entire transmission or just inspect, put back together and seal it up? When I drained the fluid, there was gold flakes in the oil, synchro dust was what I was told and nothing to worry about. No steel flakes or chunks.
My second question... I have yet to look into the transfer case to see its known condition. Just a fluid change. While the trans is out, is it the transfer case worthy of any work? Everything feels fine but I don't know what problems the dana 300 could have in terms of issues. Is there any advice or upgrades I should do to the T-case while it is out?
Thanks in advance!

It's day whatever of quarantine in Ohio... My work has sent me home with my computer so I can work from home. Hmmm "work" lol
Just kidding, I'm actually working when I'm supposed too. I've started to work in the garage during lunch and after working hours since the weather is much nicer now. Worked on the CJ more in one week than I have all winter! I sent the hood, doors, dash, and tailgate off to be cleaned of paint and rust. $460 for all of that, a little high but I'm not going to complain because the guy does a great job.
Meanwhile I finished the other fenders cover panel (Picture 1). Wasn't too hard, just tedious work. It wasn't nearly as bad as the drivers side but I'm glad I replaced it. I started body work on the fenders and grill (Picture 2). There wasn't much metal work to be done on the fender but the metal was wavy from stamping. A purest would probably say, "leave the waviness in the panels, that's how old jeeps are supposed to be". So let the sanding begin!
In between working on the CJ, some of you might have seen some pictures of the M715. Yes, I know its not a CJ but I like to incorporate some other stuff I do on this thread as well. This up coming weekend the motor should be going in it! It was supposed to happen last weekend until we broke the bearing retainer to the adapter kit... Here's where we are on it!

No updates right now but I thought I would share something I find pretty cool.
This past weekend, I was out at my grandfathers property looking though one of the barns. Up on a top shelf I found some old AMC parts...
Three unused filters with one never being opened... I've been running in and out of those barns for 20 years and Just now saw these. I asked about them and he said he put those up there in the 80's before leaving AMC. I'm sure they were from Whitewater AMC Jeep in Indiana. Definitely keeping my eyes open now that I've found this, Jeep manuals and other weird stuff. Is it worth anything? Who knows, I find it cool and is going in my collection of AMC stuff that I've found over years of going though those barns. Just thought this was cool. Some of you may have seen it on facebook already
