I'll post 4 more pics before I head out to the New England Rockbusters Construction Show in NH.
Once I disconnected engine I moved the final onto the pad. This view shows the temporary legs I made for the back and the next shows same at front. Just used scrap to do this important job. Third view shows the 2 long 5/8 bolts I put in the top holes so I could slide the finals off the trans case. A floor jack on the outer axle and it came apart easy. Lastly I hooked the housing to my Hyd. lift and took it away from the main body. I now have access to the most important components of the steering. I will take the clutch packs apart and rebuild if necessary because I want this tractor to steer correctly. Ed B

Great progress so far. Would be interested to see a video of it going when you are finished. Well done.

So is that the traditional way that the clutches come apart in that cat? I have seen plenty of IH pics, but not any cats.

Basherman As far as I know all the early Cats including Models 30, 60 10,15, 20,22 etc all have their clutch pacs inside the final drive housing which makes them difficult to repair and rebuild. This isn't so bad for me because I am dismantaling the whole tractor but would be a problem if you needed to do this on a working tractor in a hurry. I have run across several early Cats that only steer in one direction [including my 30 Orchard taildragger] because it is so much trouble to fix them. The IHC system used in the TD series is much more fixer friendly because the clutches come out the top and the only hard part is getting at the pesky bolts down inside the trans housing out and later back in. I haven't taken the clutch pacs apart yet but it doesn't look that difficult. Ed B

Things have started to get busy so my time on the 25 is more limited. It has also turned out to be a much bigger job than I anticipated at the start. I'm starting off with pics of the Cat 20 parts tractor recovery from a revine in W. Granby Ct. Had to cut trees and brush and move piles of junk that were in the way. The owner had a skid steer we hoped would move it up the hill. The first pic show the 20 finally uncovered from brush and construction debrie. Tree is still across the hood. Next pic is owner Duffy Magee trying to move the 20. After sitting in this spot for 8 years it crawled right out clack,clack,clack. Next is 20 being pulled through a very narrow area around a garage. Last pic shows starting to pull the 20 up 30 degree angle hill which in the end took a New Holland and skid steer hooked in tandam.

This set of pics show the final run up a 45 degree driveway. My truck and trailer were waiting at the top since there is no way I could have gotten it down into the 20's resting place. The first shows the tandam push pull moving up the final driveway. Next is the 20 back at home in Waterford, The side view shows what I hope to be the savior for the rarer Model 25. The last pic shows the winch setup on the back. It is homemade but nicely done. It is a capstan style and was told it was built to pull high line cables for the power co. in the 40's. I don't know yet if I will put it on the 25.

The last set of pics get back to showing some of the progress so far. I spent 2 days rebuilding the track frame assemblies. This pic shows the right side pieces after coating with Awotrol Marine Oil. The can in the pic is one liter and cost $30.05. I am brushing it on because spraying would waste a lot of it. Second shot shows completed transmission that has been cleaned and also coated. Third pic shows pinion drive gear on 20 which turned out to be completelt worn away due to no lubricationat all. Interestingly all the bearing are good. Hoping gear set in 25 will fit as replacements. Last pic shows the main reason for getting the 20. It has nearly perfect tracks, rollers and sprockets. The only problem is they have been cut out so they will work in snow. I may make a jig to tourch them out more evenly since they were hand cut and not uniform.

Nice looking pins and bushings! Poor thing must have made some noise when driving with those worn pinions and no oil!
