transmission problem!! Help

I'm baffled I am building a transmission for my 1916 engine using 1925 brake drum with the replaceable lugs but not the improved brake with larger braking serface . so its a standard one inch drum width. low drum 1" and reverse drum 1" after assembly with the drive gear on the brake drum shaft pressed on so that the flange is flush to the top of the shaft as the book shows. I am getting what I think is far to much end play about 3/16 of an inch . I know that this assembly does not require any thrust washers between the drums. I compared the drums and shaft from the flywheel to other parts that I took out and they are all the same length. Just can't figure why the reverse drum has so much end play. Any sugestions much appreciated. Frank pkny

Well here goes I think I found the problem. After reading the repair manual for T transmission, I found the likely sorce of the exessive end play in the reverse drum. Looking over the entire repair job when I installed new bushings in the brake drum shaft it is imperative that the bushing that goes twards the flywheel be indented into the shaft 1/4" below the end of the shaft that allows the shaft to be flush with the main drive shaft off the flywheel. I have not put it back together yet but feel confident that that was the cause of the excessive end play. I did recess the bushing late last night could see that it now lets the brake drum shaft go flush against the flywheel. Prior the that it only went to about 3/16" away from the flywheel thus giving me the end play of 3/16" + or -. The reason for the bushing being indented is that the main shaft has a radious on the end where it flares out to the flywheel connection flange. Whish I could post photo's but my program has caused me problems with my outlook express so I had to remove it and till I can figure a new way to download photo's from my camera I can't post any photo's. If anyone has to rebuild a transmission this is a valuable lesson. My next step is to try my hand a ballancing the drums and flywheel. Frank pkny
 
Thanks for the tip. Is this something that is mentioned in the manual, or did you have to figure it out yourself after looking how the parts went together?
 
Not in the original Ford manual (not found by me anyway) . I purchased a manual from Langs and it is stated in there as "caution, recess that bushing 1/4"
 
Got the engine and transmission together . Converted a non-starter engine to a starter. Put in rebuilt magneto and flywheel and a starter hogs head. Got it all done and went to put the starter on and bamXXX###$$%%%. The pedal shaft and pedal would not clear the starter Bendix drive. I used all my non starter parts because they were in great condition. Did no know that the starter cars use a different pedal that clears the Bendix housing. Dam now I have to take off the hogs head and replace the low gear pedal and shaft. One step backwards! Any one got a decent plain face pedal for a starter hogshead? Frank pkny

Checking end play with the drive drum installed. Note the countersunk bushing. Also note using a drill press for a easy type quick spring compressor.
 
Got the engine in today! Had to do hunnydo stuff most of the day, but able to work on the T Sat and Sunday. Today fixing things on the farm , will try to post some new photo's tomorrow. Did it alone, used an engine hoist and a come along to pull the engine back while with the other hand lined up the ujoint. cute trick , have figured out how to do most things alone. My son always to busy with the girls.
