While in the process of rebuilding my transmission I found the Idler Gear to have a lot of slop on the shaft. After checking the specs and miking the shaft and bushing I decided to replace the bushing. Searching the forum and reading the manual I found that it was more than just pressing out and pressing in a new one. I also found that this is a part that needed to come from the dealer. I am not a machinist but here is how I replaced the bushing.
The first step was to find one. TM does not have it so I found one at http://farmallparts.com/products/?view= ... t_id=26727
The bearing was very thin and I did not dear press the old one out with the new one. I found a 12 mm Craftsman socket was just the tool to press it out.
Using the arbor press it slid out very easy.
Pressing the new one in was just as simple.
The manual calls for reaming the bushing to some tight tolerances
I was able to purchase a reamer that will adjust from 0.59375 to 0.65625. http://dewitt-tool.com/DWRRADJCreamers_adjustable.aspx I actual ended up getting a full set at Harbor Freight.
Next was figuring out how to adjust it to what I needed. Once I messed with it I found that working the adjustment nuts on both ends of the tool that I could adjust to tight tolerances. Working with a micrometer I got it to where I needed to be and then checked each cutter for the proper measurement.
I was good to go at that point. I held the gear in one hand and the reamer in the other and slowly worked the tool thru the bushing. Spinning the reamer as I pushed it thru.
Not much is removed as you can see the small remains of what was reamed out.
I put some fresh oil on the shaft and slid it in. I turned very smooth without any slop.
nice job, this should be in the how to section.
Nice job, Wally. Did you find what was causing the problem in the transmission? Ed

Concise and to the point. Only two things I would add, use some oil before pressing in the new bushing and cutting fluid/oil when reaming, and do not reverse the direction of the reamer (always turn clockwise).
Where you are, right now, is of absolutly no use unless you are able to get away from it, FAST!
Yes this is a great how to I am sure as soon as Barnyard or Rudi sees this it will be put their

Yup, very nice How To. Bill will copy this to the proper How To Forum and it WILL be in the CBoK shortly I gonna be using this one I think as I have a tranny on the '56 to redo in the very near future.
Wally, which reamer set at Harbor did you get? Was it this one? 11 Piece Adjustable Hand Reamer Set Item #38577
Jim I did not see that they had it there. You are a bargain hunter.
Rudi that is the set that I purchased at Harbor Freight
Ed I took your advice and picked up a set of gears from Hamilton Bob. I think the issue was with the first/reverse gear. I found a small piece of steel from a broken shift fork in the bottom of the case. I think it must have jamed in the gear at some point and did some damage. As you suggested I have replaced the main shaft bearings. The rear main I used a sealed bearing and turned down the shaft to accommodate it. I also replaced the 2 differential bearings. I purchased the gasket and seal kit from TM. Should have it back together shortly. I hope its good for another 60 years.
This has been copied and locked in the how to forum. Thanks Wally!
