So I posted a bit about this in another discussion on alternative starting methods for cat 22 but here it goes again. Perhaps to a broader audience.  
This cat 22 was abandoned in the woods in the late 90's a few properties over from us. We discovered it around 2008. Covered in a disintegrated tarp and buried in pack rat nests. Fast forward to Sept 2022, thru quirk of fate owner of property, approached me and said i could have machine. After a day of uncovering, cleaning, and prep work I was able to get it to fire up and run on priming fuel. Had to have carb rebuilt  and a few other issues taken care of. 
yesterday was the big day of trying to drive it out of woods. It's down a big hill and about 1/2 mile to get to our house. I did a bunch of cutting etc to make a path to get out. Got machine running and only the right track is getting power. Not so good.  I tried forward a d back, working track clutches and brakes.  No luck. I opened brake adjustment  compartments  and noticed that the left one had a bunch of oily gravy. Looked in book, says it should be dry. Drained it and dumped in solvent like it recommended to clean clutches. Sure enough, now left track will work. 
got partway up big hill and machine lost power and stalls. Not good. Chalked it and lowered blade. Got it restarted and now right track isn't turning. Dumped some solvent in that side. Success, both tracks turning ok.  It took nearly 6 hours to get it home. So quite an adventure but made it out. A fun family activity.

So some questions:
1.on hills, engine bogs down. Is that normal? It made it but I had to clutch in a few times to let rpms increase. I feel like it shouldn't do this. I feel like tracks are too tight, I will adjust. Just looking for input on this issue. 
​​​​​​2. Sometimes when I start it in neutral, I can't shift into gear cause it grinds. If I start in gear with clutch in, shifting no problem. And once it's running, I can go from gear to neutral and back into gear no problem.  What needs adjusting?

 

Any cat 22 experts, please chime in with your expertise. I have book but some parts aren't clear. Thoughts on track clutches, main clutch, whatever.... I'm looking to put this machine back to work. Thanks

hello , the clutch housing just might need a good wask out ,you might get lucky and it just oily in there .
depend which fuel tank your using ? if using big tank fuel pump may not be working eought to pump fuel at higher revs ,i used the little tank and kept full ,gravity feed to carbie , little hole in fuel cap clean ?
looks like a nice little cat

Hi, tkgeorge99.
Good catch - looks like a pretty clean machine and the hydraulic dozer and winch are a bonus.

Neil's idea of pouring water over the tracks while driving is a good one but it is a LOTTTT easier if you can drive it repeatedly back and forth through a puddle a few inches deep. Just don't get it bogged or the fun will begin.

I have a bit of a soft spot for 22s. My parents had one on the family farm and it was the first tractor I ever got to operate by my ownsome. It had a dozer blade that was raised and lowered by a hand windlass which was no use for grading but i spent some very pleasant hours flattening scrub and pushing fire heaps together. It had previously been converted to remote control via ropes from a harvester and so the clutch control was a hand lever which you pulled back to disengage the clutch. I was 11 years old.

Just my 0.02.

Thanks for replies. Is the best way to clean clutch to take off cover down by flywheel? I guess I'm not sure where to access. To clean, brake cleaner? I think clutch pedal needs adjustment as well.

As far as cleaning tracks? How bout penetrating oil on the pins? I know is says not to lube tracks but the pins?
Good point about tracks, they might just need a workout to loosen up. But I did drive it a half mile and they seem tight. No sag at all.
Engine runs super sweet but I'm worried about the bogging down on hills. Less useful if it can't climb. I feel like in first gear it shouldn't have any trouble

How do I adjust main clutch? Which access hatch?
