You might be able to jack up one tire an inch off the ground. Try to rotate the tire... If everything is in NEUTRAL, the tire will turn.

Have the rear tire off the floor . Only time it won't turn is when reverse gear ? is slid all the way forward . I assume it's in reverse and second gear ? I moved some gears around and now it turns pretty freely . Took a pic that my fav son will post soon . Hoping this is neutral ? THANKS !! Just realized I have the power director in neutral .

I put the power director in high and the wheel still spins . Should've also said that the second gear from the front also spins . THANKS !!

Sure sounds like you are making progress. The Power Director engaged in hi/lo is a good catch to determine is the gears in in the Neutral position, as you move the wheel and the gears.
The pic will help some of the more knowledgeable in the Forum give you indication if all gears are in Neutral
I remember a common expression at work over the years "self discovery is the best form of learning" and it sounds like you have a lot of that going right now!!!
Good luck with your project

Thanks Robert ! Maybe I'm headed in the right direction . Still wonder why it hung up in the first place ? If I manage to get it up and running again I'll be very careful changing gears . Thanks

I am sure you will be up and running again. I see your photographer has posted a great pic. Hopefully, a Forum expert can tell you if your gears are in Neutral or not. Aligning with the Forks as has been well presented above, and no gear movement when you turn the rear wheel are huge steps in the right direction, and are the limit of my knowledge
As for how this happened in the first place..... as it has happened to me several times before I corrected the Shifter ball clearances with the Notch....
Possibility 1.........perhaps someone (no names please) banged the Shifter with their leg, as they were getting on/off the D15 before you discovered the problem. There is not a lot of room between the seat and the Shifter knob - I have had to wiggle my leg thru numerous times, mostly when dismounting, and that is not good because you could end up forcing the shifter in a undesirable manner. I know I have done that a few times. Usually, I leave the Shifter in Neutral, which provides a bit more room for your leg, but sometimes I forget, leave it in Reverse or 2nd and end up popping the Shifter forward
Possibility 2........when I was a youngster is was lots of fun to climb on farm tractors (that were not running) and turn the steering wheel, turn on the lights, etc, AND MOVE THE SHIFTER THRU THE SHIFT PATTERN. My experience would suggest this in not good for a worn, 50+ year old tractor shifter/transmission. Now your tractor was in the garage with no loads on the gears etc, but if the shift pattern was not followed very carefully there could be a possibility of "sloppy shifting" leading to gear lockup
I could easily see either of the above examples happening to my tractors, either by me or visitors, my son, or my grandchildren when they visit
My old D15 II is a great tractor, but have learned to be really careful with the gear shifting, and there are no issues
Good luck with your project

Robert it's guys like you that make this site what it is. You're over 2,000 miles away and took the time to help me out . I've received help from many people on here over the years . Thanks again to you , Steve , Dr Allis and everyone else . Hope I haven't just jinxed myself. Should also say that I have nobody to blame but myself .

Thanks ACinSC, just trying to help out. This Forum is so valuable to Allis Chalmers owners, especially when they are in need of information/guidance to get their equipment working again.
I tried comparing the locations of your gears from your recent photo to the pic from the D15 Transmission article noted in an earlier post above. They gear locations look very similar with no significant differences. Not sure if the article pic has the gears in Neutral, but you would think it would be in Neutral before they opened it up.
The online AGCO Parts Book, or any other good D15 parts book, shows the Forward gears and Reverse. This would help identify the gears that need to be loose to satisfy the Neutral position condition. A further check is to turn your rear wheel, and if none of them move, then you should be ok to proceed with the forks/side plate installation.
steve(ill) provided an excellent description in an earlier post on how to install forks/side plate. Once you have completed his suggested procedure, including the final step - shifting you should be in good shape.
Perhaps secure the Shifter at this stage as well
As a final check, you could shift thru Neutral and all the gears, turning the rear wheel a bit after each shift, to see if the gears are engaging properly. The rear wheel should spin freely when the Shifter is in Neutral, and should not spin in any of the five gear positions
If you get that far, and everything is looking good, get on the tractor, push in the clutch pedal, start the engine (idle), put the hand clutch/Power Director in hi or lo, gear shifter in Neutral, and SLOWLY /Gently let the clutch pedal out...........the rear wheel should not move
If the rear wheel does not move in Neutral, then try each gear following the same procedure, and you should get the corresponding rotation for each gear. Once you have confirmed Neutral, and all gear positions are working, you can button up the remaining bolts on the side plate, return oil to the transmission, lower your wheel, and take D15 for a spin
Good luck

AC... i wish i could help more at this point, but i really can't "LOOK" at a set of gears and tell you what is engaged... The "DOGS" on the side of the gears are NORMALLY visible when you are in neutral... The gear to the LEFT of the page has the DOGS visible on both sides... The lower gears on the RIGHT side of the page, i dont see all the DOGS.. Wonder if that gear needs to slide a little, but i dont know for sure... maybe just the angle of the photo.............. again, if the tire turns, then you SHOULD be in neutral ( with PD engaged). Sometimes you got to install the plate a couple times to get it RIGHT.. Trying to shift it with 1-2 bolts installed is the final test.

Pulled the rear tire/wheel today . Took a good look at my service manual and it says to engage the reverse idler gear , then put pinion shaft reverse gear in neutral . Then put pinion shaft coupling in neutral and then reverse shift rod in gear . Very confusing . Gonna order a gasket Monday so I can put it on . If I ever get this side plate right I don't wanna remove it . Should say that I tried putting the side plate on with everything in neutral , at least I think it's in neutral and had no luck . THANKS !

More searching and found D14 (very similar to D15 - side plate transmission access) info and found this very interesting thread which I think is very applicable to your situation
This guy probably had the same problem you encountered!!!!
The section on Shifter Removal, last two at bottom of Thread, looks very promising, and it seems to line up directly with the information you quoted from your service manual regarding engaging Reverse Gear. The service manual is providing direction to reassemble the shifter mechanism and the YT article is directing how to open up the shifter assembly........how to open it up and how to close
Both indicate that the key to opening or closing is TO HAVE THE SHIFTER IN REVERSE so you have minimal interference as you carefully remove or insert the sideplate/forks mechanism into/out of the transmission
It is like the combination of a safe or lock.........put the shifter in reverse and the forks/sideplate can be removed with no interference, or the mechanism can be re-installed
I know this is different than what we have have been trying to do (everything in Neutral) but I believe it is worth trying.
The directions in your manual are essentially what happens when you use the Shifter to put the tractor into Reverse. All of those items mentioned move into position, when you move the Shifter into Reverse. The YT article calls for the same step before you open the sideplate/forks mechanism. Two different ways to essentially line things up so the sideplate/forks can be removed.
So here is what you need to do.......... 1. move the gears etc as per your service manual, engage means move to a position where the gear turns when the rear wheel turns........neutral means it does not move when the rear wheel turns (there should be a diagram in your service manual showing the gears and their identification - if not go to the online AGCO parts manual for this info
2. Move the Reverse Gear Notch on the Sideplate/Forks assembly into the engaged position (simulating putting the tractor into Reverse Gear). This is the reference in your service manual "reverse shift rod in gear". The YT thread refers to using a screwdriver. after removing the shifter to do the same thing
3. Now the gears are lined up (step one) and the forks lined up (step two) and you should be able to insert the sideplate/forks into the transmission housing with minimal interference
4. The YT thread mentions "if you hold your mouth just right"....I think this means do it carefully and don't sneeze/cough
5. Hopefully this works and you can get the sideplate/forks assembly in place.
6. The directions noted in previous messages to perform integrity checks, shifting, manually turning the rear wheel to check each gear, then using the engine power to turn the rear wheel still apply
To add confidence to this slightly different approach, here is a neat piece of info I found titled.....Installation Procedure of transmission Shift Tops". How to line up the gears/forks for WD45, D17, D19, 170, 175....all with top shift tops (D14/D15 on side) and similar shift pattern. The document is from Sandy Lake Implements. Perhaps they would have a similar document for D14/D15
The steps for the WD45/D17 are very similar to our example, with minor difference due to Reverse on side of shift pattern, not in middle like D14/D15
Hopefully this additional information will help you progress your installation
Good luck

Here are a couple of additional info reads I found in the D14 searches. The YouTube vid shows the D14 transmission and commentary on work performed. The second thread has pics of a D14 transmission repair. You can see the D14 transmission looks very similar to the D15.
Hope this helps with your work
Good luck

 Been a couple weeks since I last posted . I see my attempt at pic posting didn't work . Today I put on my new gasket , knocked the side plate fork in reverse and put the plate on . Per my book I used a big screwdriver to put the shifter fork back in neutral . Wheel turns so I guess I'm good . Then I installed 2 new shifter pins ,the shifter and a new washer and lock ring . Shifter seems to work ok . Next I'll put the fender and loaded tire/wheel back on , add trans oil and see what happens . THANKS everyone for the help .

Great news.......Congrats on your project. Looks like you are on your way. It is such a rewarding feeling to get your tractor back together.
I got a couple of email notifications, (automatic by the Forum if you elect to receive email notification of additional posts after you have posted to a thread), one yesterday and one today, with an attached pic, which I could not open, showing you as the poster. I figured it was some sort of spam as the Forum did not seem to record the post?????!!!
I have been using my D15 II the past week (first work with it since last fall) and had to remind myself to be careful shifting, and not rush or force the shifter into position
Hope it works well for you. Happy shifting!!!

Yeah my picture didn't work . Sure hope I soon have my old D 15 up and running . Thanks again for all your help . I also plan to shift carefully . Still wonder what happened in the first place? If it hangs up again I'm going to pull the shifter and try to align things with my big screwdriver .

That's the spirit. Now you are so much more knowledgeable of the whole shifting mechanism, having seen the internals, and worked with it. It really helped me to work thru my situation, and read the similar problems others had encountered.
Self discovery is very satisfying!!!
Good luck

Congratulations on your first travels post re-alignment of your trans/shifter parts. What a great looking D15 and kudos to you for bringing it back to life.
I have much appreciation for people who take the time, energy, COST, and perseverance to restore items of whatever type and return them to useful service. Of course, if it happens to be an Allis Chalmers that is even better!!
Best of luck with your project
