22 Track removal

[pbamburak]

Hello all,

I am trying to remove the tracks from a 1936Cat 22 S/N 2f5388. I found the master pins and will remove the cotter pins. Do I simply drive the master pins out or is there something else I need to know about this job? The parts book picture of the master pins looks as if the center section of the pin is larger in diameter than the ends.

I would use some heat on the bushing and some WD40. Wear eye protection too when hitting the pin. Some pics have plugs on the edges with an expandable master pin but yours sounds different if you had pins.

I am located in Blue Bell, PA and restored a cat 22. I am working on many other machines now. How long have you had the 22? Is it from somewhere local? If you are looking for parts for your machine, I may have some, espically undercariiage parts.

Yes, Just drive them out with a suitable sledge hammer and punch or a B&O hammer. You will probably need to have someone hold another sledge on the opposite side to dampen the hammer blows. Sometimes on the pins there's a ridge worn and it will hang up when it passes through the link. If all else fails burn the pin then drive the pieces out.

from what ive seen heard and know you also have to pull the track links around the master link together a bit to take some of the weight off of the master link pin and sometimes if the links are rusty or dirty or corroded you might have to heat them up with a rosebud head on an oxy.-aceteyelene torch,then get a sledge-hammer and a thick punch and pop that puppy on out of there, also keep a can of WD-40 handy you're gonna need it. i have my own 22 tracks i need to replace real soon so i've done a lot of research and questioning on the subject myself. GOOD-LUCK

I just removed the tracks on a 10 with those type of master piins. The pins are actually smaller in the center. They make contact on about 3/4 inch on each end of the pin. I had good luck by getting the pins lined up on the back side of the sprocket so you can get a good swing with the hammer. You will need a back up. I used a 2 pound sledge with a 1 inch pipe backup slipped over the pin wedged up against the drawbar. Don't try to hold the punch with your hand, Weld a handle on it or improvise something. when you start driving the pin out put something back in the cotter pin hole because you might collapse it. Mine broke off so I just ground them down with a dremel and left them. Wear safety glasses. - Wally

Thanks to everyone who made suggestions to help me out. I'll be giving it a try next weekend when my older son is home from school and can lend a hand.

I found these two 22s in Southampton,NJ behind a diesel repair shop on Rt.206. It was a case of driving by one day and stopping in when I spotted a load of junk - ah - treasure in the back lot.

I am set for parts for now.

Thanks,

hello pbamburak ,nice find ,if you are taking a link out of the yellow 22 i don't think that they are worn enough yet ,i can still see some frame out the front of the idler ,plus the tracks look like there too tight .should be up to 2'' sag on the top of the tracks .they look ok from the pic but if you could post some close up pic for a better look ,bruce oz

Bruce,

After A look thru the operator's manual I too realized the tracks are too tight. I am taking them off so that I can get a good paint job on the machine, and I do not plan to remove a link.

Thanks for your input!
