I am told I am a Essential worker but work has been slow due to the governors order to stay home and close everything. This left me with time on my hands and many Old Cat Iron projects. I decided I was in the mood to jump into 2 big Twenty's I have. 2 tractors with problems to make 1 nice machine.

The machine to be sacrificed is a narrow machine from California that I brought home, got running and discovered it had a bad final and the transmission case had been broke and welded, not prety but nice track frames.

The other is a wide machine with stuck engine, clutch and 1 staring clutch issue, it has excellent tracks but the brakes were froze up.

So I removed the engines from both of them, moved the good engine to the wide machine, I did remove and clean the clutch and grease the pilot bearing that was close to dry. I then removed the left side track frame and finals from both, getting the brakes freed up on the wide machine was a huge pain, I also removed the steering clutch to inspect, and in this case replace the thrust bearing with a better used I had. I reassembled using the track frame from the California tractor. In the process I decided to install a PTO I had for it along with a better draw bar and hitch plate. The levers for the steering clutches were sloppy, the pictures will tell that story. The next step is to get it turned around in the shop to do the right side. This has been a LOT of work but has kept my occupied.

More progress this weekend

Looking good Steve...…..do keep posting progress pictures.
Have a good evening....Bill

Today's progress--slow

I got the machine moved and removed the right side track, frame and final, The sprocket has a broken spoke and needs to come off but is was not going to move. So off with the cover and sprocket, I have lots of parts. The pin the brake pivots on is proving to be difficult on this side also. This is where I quit for today


Jan , you must be referring to the small 15 that I painted the wrong color yellow. I did paint it however I dont like to paint. TY.

The brake pivot pin was very stubborn, I drilled about 1/2 way through then hit a hard spot, Taped it for 5/8 NC and put the puller to work, I still added some heat as I was concerned I was going to pull the threaded rod out of the pin. In the end I won. Upon further inspection I discovered the pinion bearings were in sad shape so why not go through the whole final drive.
