Did you pull the 7111 countershaft out first? It's been a day or two since i worked on one of these, but I think it has to come out so the cluster gear can drop down out of the way before the mainshaft or input shaft will pull out.

YES!!! you shouldn't need force. You should be able to pop the front bearing out about halfway before the gear hits the case, but that's as far as it goes.

I got the shaft out. The front bearing was in the hole really tight. I moved it with the hammer and then used my shop press. I finally got it out. I probably F'ed the main shaft up. I'll see if I can remember how it goes together tomorrow. It's too late tonight to screw with it any more. I have absolutely no patience when something doesn't want to work like it should. I gave it plenty of time to go the right way.

No, I didn't remove the 7111 shaft. I'll have to wait until tomorrow to see if and what I might have screwed up. It's too darn late tonight, the little patience I had is completely gone.

Julie,
Not a stupid question. No, I wasn't. A real man only uses a manual after he really mucks something up. It was late and I figured I could just disassemble it. BTW, I thought it would be a simple procedure:
Julie, just giving you a hard time. If I screwed this up it's all my fault, no excuses other than it being late, I was tired and in a hurry. I screwed up by not first grabbing the manual and seeing what it had to say. I'll take a look at the tranny some time today and see if I screwed it up.

Yyyyep! Post #18 - the dreaded old 7100! Four teeth.
That's the same thing that happened to the original 3 spd I had in my 55. As I recall it was VERY easy to get that out. You just remove the input shaft cover and shaft, pop off a bearing snap ring and pull the whole gear cluster first throught the front hole about an inch until the back is out of it's bearing, then up and out.
But, be careful to do this all in a large pan or wash bucket. There are roller bearings in there that always seem to stick together for a minute then all fall out.
I think that gear just slides offthe back the new one back on. Be sure to replace both front and back oil seals! You can probably do all of this in less than 30 minutes!
Have fun!

Dick,
I checked out the links when you first posted them and thought they were very helpful but for some reason last night I didn't think about referring back to them. Basically, I'm a moron. My brain must not have been firing on all cylinders last night.

I found the needle bearings everyone was talking about. I think I should have left bottom shaft alone, two of the little rods were broke in three pieces. I guess it was probably a good thing to pull the bottom shaft so I found the broken pieces. I have a bearing company about a mile away and I hope I can buy some there. I think they'll also have the seals. I've had pretty good luck with them being able to match up bearing and seals.

The whole reason my 1st/Rev gear had bad teeth was that the PO or some mechanic knocked one of those rollers out while installing, and it got between that gear and the reverse idler, and the cluster.
How does the cluster's rear thrust washer look? Is the case surface the washer bears on chewed up? Before you go much further make sure it isn't, because it's a deal breaker...

LOL, well, it is a pretty simple procedure unless you forget something or it fights back.
You're not an idiot at all. But I know I said it would be easy in that one post and I guess I was a little late saying "this is how easy I remeber it, but don't take my word for it, be sure and check with the manual."
It almost sounds like it might be time to look for a different transmission to install. Usually when all the stuff goes out that you are describing, the rest is worn or close to shot (wear to gears etc), and just installing replacements for the broken parts might not fix what caused it.
BUT DON'T TAKE JUST MY WORD FOR IT!!!!!! LOL!!!!
