Hello Markds3
I may be wrong as I have never worked on a D2 but if you are only working on the clutches and the bevel gear then you shouldn't need to break the tracks.

The D2 is notoriously difficult compared to the larger tractors (D4 included) as the only way to access the steering clutches is to pull the final drives, and to do that you need to remove the tracks, track frames, pivot shaft and drawbar.
 

Ah OK thanks for that info. As I said I have never worked on one so I did not know it is such a huge job to access the clutches.

One thing that worked well for us is a big chunk of railway line with the end cut to fit near the pin and the other end anchored. Makes a huge difference flogging track pins out.

lol....yea

Well, after unsuccessfully trying to remove the pins with a sledge, even after applying heat, I was able to borrow a 60T portable pin press from a engineering shop (that builds 30T forestry harvesters) that I do business with. I'm very glad I did, as the master pin on the RHS track approached the limit of the press! No way I was going to move it the way I was trying. It certainly let go with an almighty bang! Very very little pin wear as you can see.
         

Thats great!

right tools make all the difference. hope fully we never have to split the tracks on our machine.

I would consider using a standard master pin when you assemble the tracks. The pin you took out, was pressed in like the other pins and not a correct master pin. Then you won't have any future problem spitting the tracks. Bill

Thanks Bill, apparently they are the correct master pin, and are exactly what CAT would supply today if I ordered new ones. I just have no idea why the RHS one was so tight (maybe many years of accumulated dirt and rust?) as the LHS moved much easier and let go with only a small pop.

I have not run into this solid, current pin that is available from CAT. I think a solid master pin would have to be pressed in so it wouldn’t move. There must be some information on this solid master pin installation and removal.  D2-5U13753 - master pins - please check my understanding - ACMOC Bulletin Board - Antique Caterpillar Machinery Owners Club  I forgot about this discussion.
