interesting couplingshaft found on 31AA anyone know about?
i have two AA dump trucks. i was not sure of years 30 or 31. i took intermediate shaft out of one and found a gear that bolts on output shaft of the 4 speed. the next truck i took apart has a u joint on the back of the 4 speed. this must be the unique set up that is discussed on page 27 of jim schilds AA shop manual. it looks identical to the photos. i guess the advantage of this is that the rear end does not have to be pulled back to get the transmission out. does this sound accurate to those that are knowledgeable about this. seems that if this is true this is the coupling i should use. now i just have to find a good four speed case that is not cracked. i also have 2 PTO assemblies that bolt on the four speeds if anyone is interested. let me know, and thank you in advance, kevin in ct

See the 1932 Service Bulletins for this shaft. It was a good idea;, saves a lot of work to replace a clutch.

What brand are the PTO's ?
Always one bad decision away from a good time.

i am wondering if this special shaft will work with a 28 worm drive rear end. i think someone told me once it only works with bevel gear rear end. any ideas out there? thank you, kevin

hey thank you for the photo. yes, it sure does say bevel gear at top. i guess i will not be able to employ this great update with a worm drive. thank you. kevin
