Ok, I can usually get these things knocked out, but I'm a bit stuck here and if welding isn't strong enough, I'm a little panicked... I got the outer part of the bearing free from the case, but it's stuck on the shaft like hell. Breaking welds trying to free it. Any ideas?? It's a damn mess..and yes, big clip was removed. Could it have gotten off kilter and jammed on the ring groove?

I got it down to this…I guess easy to just cutting wheel the outer off and then inner to cut/chisel?

Got it! Pheeew…I’m not one to panic doing this stuff, but man, that almost got me..lol

That bearing is a MOFO! I have the SST for the transmissions that I bought in the early 90s and that one bearing has almost ruined my long jaw pullers!

Considering that there’s a snapring in front of it that typically isn’t doing ANYTHING, I don’t see the harm in buffing the shaft with a little aluminum oxide so the fit is a little looser than pucker tight to reassemble.
 
Yeah, that was some real, off fashioned, fun…lol. Good news, I finally got it all buttoned with new synchros (not the 1-2 billion dollar one of course) and installed! Helluva time lining up trans for insertion…on an incline driveway..finally got my son and my crane out to help..pheeew. Just in time for our ice storm..cruising around in 4H has been nice..:-)

Well...I'm back..:-(. Something started clunking in the transfer again.. Looks like I'm gonna try pulling just the transfer itself to inspect. Oil looked a little shiny, too. What the hell could've happened? Everything is new in there. Ugh. I'll post up once I have time to pull it.
 
Well...managed to yank the transfer without disassembling everything else...transfer gears are trashed again. Not sure what the hell could've happened. Everything thing went together clean and spun nicely..a little bummed. Looks like the Idler gear and hi speed gear are done. Hi speed is the smaller, correct? Somehow the Low speed didn't get damaged. I drove a couple hundred miles and she was butter smooth and quiet..got on the highway the other day and didn't get 5 miles before the clunking..

Mark, I left you a voicemail for more gears...:-(... Thanks!
 
I feel bad for you. Unless you can magnaflux/dye chem/X-ray everything you can't be sure there isn't some hidden damage like cracks developing. I'd not be happy with the wear pattern I see on the gears.

Got a break between jobs and got it. Luckily I looked here before calling. It looks like, directly across from the head of the cotter pin on the shift fork, that you have a chip off one of the teeth of the output shaft. 😱AND I have a hard time believing that bent tooth on the idler didn’t transfer force to the low speed gear.☹️

In my opinion, you should replace EVERYTHING, or just move on to a different case. I can help with either, just not right now. I have three remaining work days for the next two weeks, and six days worth of work that I am already committed to. So if you want to get any of those things from me, it will be two weeks. I had to come in on Saturday (I haven’t done that in years) just to get @lazarus18 order out in a timely manner.

Oh man...:-(..I wonder if should go for a nice complete, used transfer case? What's that run? $$? All my bearings and seals are new...Ugh...So you wouldn't be able to send anything out for two weeks? Hmmm...Ok. I may just be stuck waiting, I guess. She's my daily driver, so I'm hoping I can get rolling before that, but who knows...Thanks for your reply, Mark!

If you can’t wait, I totally understand. Sonny over at FJparts should have what you need, just all new stuff.

I ordered new gears to replace the junked ones. This time I’ll be painting the gears for wear patterns and make sure everything shifts properly while spinning with a drill or something, before I install it..I do NOT want to do this again…Many more things I’d like to waste money/time on..
 
I have watched several vids, of folks taking the time to properly set up differentials. Matt at matt's off road, his buddies like Bleeping Jeep and Rory have done vids. Amoron has big tubes of the proper yellow marking paint for a good price. Checking for run out is well worth the effort - looks straight only works for Steve Austin with his bionic eye. You can easily feel a 0.005" burr, much harder to sense that out of roundness in a shaft/gear/race by hand. Good instruction are a must IMHO

Way back in the mid 70's I got to help do some gear boxes on a Jet Ranger, and a Hiller plus even a Hughes 500. Big AAA surface plate, 0.0001" indicators, a like 3 ton magnaflux machine, dye chem.....

Yeah, very true. The Choppers sounds pretty awesome! Jet Ranger was what Airwolf was, right?
I was lucky to set up a few diffs with an old timer mechanic years ago. Such a process. I'll pull out all the tools for this, hopefully, last go 'round..dial indicator to see if anything has gone out of round with the shafts, paint on the teeth, etc.. On closer inspection, I also realized the high speed gear sleeve bearing came out easily when I pulled the gear. I wonder if it got a slight wobble from something and caused the teeth to briefly kiss in a bad way. I was also running in 4H during the snow here and wonder if I had too much traction on occasion and put stress on the transfer gears as well.. Either way, I will report back once the gears arrive.
 
IMHO my favorite was the Pratt and Whitney R985 radial engines my dad rebuilt. Nothing sounds like a round motor. I remember hitching rides in the crop duster going back to the hanger at night. No seat belt, just sitting on the spray tank or dust hopper. A 6' + blue flame coming out the stack burning 100/130 octane avgas flash frying bugs on the tarmac.

Back in the 90's I got to see a B-29 and a B-24 in the air. One of them was Eleanor Roosevelt plane. I heard them long before I saw them. I knew the B-24 by sight (the tail) and deduced the box it came in was a B-29.

Google says it was a C-87, a modified B-24 that she used it for a 1943 tour of the Pacific theater to visit troops.

I love that!! Man, nothing better than awesome dad memories. My heart breaks for kids who don’t get to enjoy that..My dad passed at 56, So I missed a lot of time, but the time we had was pretty epic..:-). Now I’m closing on the age I lost him at and it’s really weird. I try to spend all the time I can with my two fellas..
