On my 9N on the drivers left 2 inches above the bottom of the transmission in line front to rear verticaly with te shift lever there is a square head plug. The plug has about 3/4 inches of threads then a 2 and 1/2 inch round shaft about a 1/4 inch in diameter. Dumb me! I took it out and it will not go back in. What is it? and what do I do to put it back in?
Thanks,
John

Sean, Bob and Dunk:
Thanks for the replies to my post. Got the tractor fixed. I had to remove the transmission cover to do the job. Not to bad lots of blots that had not been off for a while and a very hard to remove steering wheel. I doubt the wheel had ever been off before.
Thanks,
John

Here is a pic from the top when the shifter housing is removed. I dont think it will be possible to get at the shaft from the top.

The FO-4 covers the disassemble pretty good. I found one exception. It says the remove the countershaft out the rear of the tranny. Dont look fun to get the countershaft gear off the countershaft. Pull the whole thing out of the top of the tranny. Its a tight fit but it can be done. That is the easy way IMHO..

Screwed up my shaft and the reverse idle gear. John Smith sold me some good ones...

Yes you are looking at the shaft through that hole. You can see the pin poking out of the casting on the left side of this pic...

Pic of the shaft.

This is what happens when the pin is removed and is cut off with a hacksaw when pin will not go back in. Mine was like this when I got it. Took a year for the shaft to walk its way out and start making noises...Thats when I decided to split and see...

This is what I found in the belly of the transmission... Shaft wont fall out but it rubs on the countershaft gear...

Thanks to all for the help. So far no luck. Does the pin slide into a shaft. When I look in the hole the pin came out of am I looking at a shaft? If so to try to line up the hole for the pin do I need to move things forward or back or turn?
Looks like I may have to take the transmission cover off and that looks like a real job. I have an old motors manual with a tractors section and lots of N Newsletters. I may have to go get a repair manual the transmission cover removal on the 9N looks like a formidable task.
Thanks
John

Put it back in. Someone did that to my 9N.I had to replace the reverse idle gear and shaft. Mine wouldnt go back in and they cut it off with a hacksaw.. Then put it back in LOL..If it wont go back in you will have to split it and pull the transmission apart. Not hard BTDT...Rebuilt mine while I was in there..[/quote:c847bda4a0]

Seems to me like quite an accomplishment (and I do remember the topic about the plug, and the hacksaw) for someone that I heard last night...

[quote:c847bda4a0="don b"](quoted from post at 22:16:20 03/25/08) Seems like you don't need to be working on anything mechanical. don b

Ok, Sean this is headed where I want it to head.

don b, is not a wrench turner.

He is a parts man.

Good parts men are hard to find.

Many times over the last 40 years I have argued with parts men, many times I have brought parts home, only to have to take them right back, and get what I needed, (don't let this inclued these under 35 year olds that now have the stage)

My point is, sometimes it was their mistake, sometimes it was my mistake, and by golley, every one of us makes them.

Seems don b is about to take that $33 brass tee, that should cost $3.95, and get it down to $15.

No one (well, except for John Smith8N) knows it all.

Now where did I put my rocker?

Im just jerking his chain cuz he said he was going to make it up to me and he never did...

The reverse idler shaft retainer pin?

Look in the hole with a good light, and see if the hole in the shaft is partially visible, or if the shaft has slid completely out of position.

If you can't tweak the shaft back into position with a long pick or similar tool, you'll have to take the tranny cover off, and see if you can access the reverse idler shaft with no more teardown than that, to move it back into the correct position.

That's all the advice I can give... It's been a LONG time since i've been in a 9N transmission, I am more familiar with the 8N trannies, but the are a LOT different.

P.S....

WHATEVER you do, be SURE the pin enters and capures the shaft, retaining it in position. I am NOT sure how far it can go if NOT restrained by the pin, but I can imagine some pretty nasty things happening!
