Tranny trouble - success with disassembly

Here is the followup on trouble I was having getting the lower shaft out of a 730 transmission. I had to make a tool to get the lock nut off. The tool is pictured. I also had to heat the lock nut with an acetyline torch to get it to break free. It took five attempts with the torch and about 500 foot pounds of torque to get it loose. Heating the nut probably compromised the adjacent roller bearing as some of the rollers got hot enough to change color. But I did finally get it all out of there. It the shafts and bearings are in really nice shape. The 2nd/5th gear will be replaced with a new one. Thanks to all who responded to my earlier post.

This tractor is an LP standard model and I am trying for a top quality case up restoration.

I have torn down alot of 2 cyl. tractor trannies on parts tractors and repaired quite a few also and more often then not those nuts are loose from banging around in the field all those years. One never knows what you will find though.

Here I am applying just a little torque to that lock nut. I definately tested the strength of my home made tool.
