AA Four Speed

Post by Farrell In Vancouver »

Thought I'd share some of what I found in the first transmission,

Farmer fix for the broken tower was to stuff a bent chunk of key stock into the slot for the shifter

A hefty dose of brazing on the ball end but not enough to make up for the well worn end of the shifter

Last one shows the wear and chew marks on the shift dawg. This thing must have been torture to drive anywhere

i've been trying to rebuild my tower after snapping my reverse lockout rod. i've got 2 questions...

1) your second photo... the ball-shaped piece in the middle of the lever... when i pulled mine apart, there appeared to be some kind of felt or rope washer in there. i imagine to retain oil or grease. however, i can't seem to find a replacement for it. perhaps it was a buildup of crud? i have no idea. can't seem to find anything similar at hardware stores. is this a "thing," or am i crazy? it was suggested i go to a fabric store and buy bulk felt to make my own washer.

2) adjacent to the ball bearings in the cover itself, there's a hole on the drivers side. on 3-speed transmissions, i've seen a threaded set screw in there. mine does not appear to have any threads; but they could just be covered from years of rust and need tapping. what is it, what do i do with it (oiling access?), and what do i put in there?

oh, and is there any component i should grease when putting it back together, or does the oil in the case cover all of that?
Rumored to be an Early '30 AA...

1) I found nothing used a seal in the towers (and wondered if there should be) but nothing is shown in the parts books. The tower cap has two pieces held tight by the main shifter spring, I believe that is all there is to be a seal.
2) I found the hole you speak of and after cleaning found no threads like the three speed has for plugging the hole. Its purpose is to afford a way of installing the detent bullets between the rails (Two)The shift rail is quite close and visable as it slides in its detents through the rail tube. Another observation was the lack of a tower vent like the A's have at the back side below the shifter. Maybe why there is no seal in the top of the shifter? If you are worried about dirt plug it with a dollop of grease.
3) I used a Q-tip covered in grease and really lubed up the spring tubes, (they were really dirty and had to use a wire to pull the springs out) ball bearings (3), detent bullets, and of course the shift rails. Once all that went together I also greased the shift forks where the shifter end fits to select a gear. A little lube on the shifter where the reverse lock-out slides won't hurt at all either. Good luck!

for some reason, i couldn't add all 4 photos to one comment. here's the other two.

sorry, no. that's not a cat turd. it's the "gunk" gasket i found after it dried out. part of it came off; which explains why it doesn't make the full loop around. it certainly seems to have function for keeping the ball and reverse lockout lubricated at that point.

it very well could be a buildup of crud... however it does seem fibrous; as in, it seems to have fiber strands keeping it together (as opposed to the whole thing crumbling at touch).

i have a cutaway image in front of me and it doesn't say there's anything there... but the lower spring and assembly is also not mentioned.

Neat! could be old wool pant leg lint and a mix of 600W.
I see your tower is marked DG&M I have one ACME and the other is Werner Gear
I wonder just how many companies were feeding Ford the gear boxes.
I'll bet each one had thier own way of sticking the towers together, and yours may have had an actual "seal" in the top.

i assumed it was felt, but i can't find any reference to it. perhaps an old timer would know.

i'd rather figure this out now than rebuilding everything without it and discovering i should have something there.

that may very well be!

what does DG&M stand for? perhaps if i research them, i may get an answer.

Fordgarage may have something about DG&M. The G&M probably stands for gear and machine, not sure about the D.

Likely a previous owner's attempt to keep water from running down the shifter and into the gear box. The "no roof" situation could have played a big part in the operation. I have one of those towers with a fitted ping-pong ball cut to provide a shim at the socket. You really don't need the reverse gate set-up to run them - I think that the gate was designed for women truck drivers...

you mean i don't need the reverse lockout rod (and components at the bottom of the stick) to operate the vehicle in all gears? just want to make sure i understand.

Well I got one of the beasties completed sans the inspection cover and she look good and seems to shift a little stiffly. Once lube up and installed I am sure she'll loosen up with use.
Here's a few pix of my progress:

Now its time to rip the engine apart and see what we'll see.
