Progress update on my Garrett 20. Original thread here when I bought it in February. https://forestryforum.com/board/index.php/topic,73068.msg1104831.html#msg1104831 .
Just to recap , when I purchased the skidder, the previous owner told me that the engine had been recently overhauled and that it was allowed to freeze without antifreeze. When he added water to the radiator water poured out from around the head. The skidder was parked for 2-3 years after the freeze damage.
When I got it home I  was giving it a close look over and noticed that the muffler was covered, but that the top of the muffler was rusted out. I took the muffler off and saw standing water in the manifold. Bummer, at this point I realized this was not going to be a "paint job rebuild" project.
I pulled the  engine/transmission out. The engine was seized so I removed the head. Soaked the pistons in penetrating oil for about 2 months and was able to turn the engine over enough to remove the pistons.  One of the liners was badly pitted even after honing. I removed all 3 liners even though I planed to reuse 2 of them because I wanted to replace the liner o rings. I sourced a good used liner from an acquaintance of my dad. Even with the pistons removed the engine had a stiff spot when rolling it over which turned out to be a split lobe on the blower rubbing the other lobe. I later learned that this is a common problem if water gets into the blower and freeze breaks the lobe. The skidder purchase came with a spare parts engine, so I tore apart the blower on that engine only to find the exact same thing.  I was able to take the good lobe from the parts engine and the good lobe from the skidder engine and make a working blower. I also installed new blower seals. There was also one freeze plug missing on the head behind the exhaust manifold, and the oil cooler housing was freeze cracked.
Fired up engine and ran it for an hour. Painted the engine, installed new input and output seals on the Warner t-98 transmission. Relined the parking brake band.
The rear right wheel was flopping around so I tore into the planetary and found the wheel bearing adjusting nut striped out. Repaired nut and re sealed planetary.
This weekend I split the frame because of the slop in the center pins. Turned out the Torrington ball bushing was mostly disintegrated.

Well, for all your time and effort you will have a nice machine that you know inside and out, and there is really nothing out there new being made to replace it. That engine looks nice! I have an idea what the whole machine will look like when you get done ;)

Good going on the rebuild.  I'm running into similar problems.  I traded my skidder even for one that was "all gone through and redone". HA!  Had a nice paint job and some new chains-other than that she was pretty much junk!!!
Been wrenching on it pretty much since day I got it.  Gaining though and will be a good machine.  I will never get another one without taking time to dig into it a bit.

Good for you for keeping at it.
Thanks for the pictures and I hope to see more !

Ya, I'm thinking if I ever buy anything else, it will be worth it to pay about a Grand to have a real mechanic check it out ::)  :)

And I bought something that ran  :D

Thanks for the support guys. Very fun project. Its so cool to be able to buy parts for this machine and no be held hostage by a dealer.
Also question for anyone has run one of these smaller Garretts. The service brake on this machine is on the back of the transfer case, seems like it is a little small for the size of this machine. Do other Garrett's have 4 wheel brakes? I bought a new set of linings and am re sealing the transfer case to keep oil out of the drum.

Most Garretts of that period had the parking brake on the transmission and a service brake disc and caliper on transfer case and front drive line. Both brakes had locking levers and the service brake operated with pedal.

I dont need one, buy would surely buy a skidderr like that if i ran across one.

Nice job

Good job on the rebuild and at least you will know what's in under you when you go in the woods. My TJ 201B  had that same brake setup and nothing else so I fabed up a rotor and caliper from a dodge dakota and installed on it in place of the drum brake, works perfect.

At least I have no grade to speak of at our property.

So I dint like the upper pivot bearing support that had one patch welded over another patch.

 
So we cut that out and made a new support out of 3/4". 

 
Painting the frame.

 
Assembled the engine transmission into the frame, got the hydraulic tank filled, a few new hydraulic lines for the steering and fired it up. At this point I took my first ever drive in a skidder! This was about mid October.

 
Drove into the shop under her own power. Note the Garrett and Skidder my Dad painted on the frame for me.

 
Some body work.

 
And this was just the last few weekends. We put the blade on to determine the stroke of the new hydraulic cylinders. The original ones were not worth rebuilding for the cost of new ones from surplus center. 

 
Fitting the cab and building new mounts. I am not a fan of the look of tis cab, but its what I have. My guess is sometime along the way someone fell a tree on the original one so they built this one.

 
Next up is the winch, gearmatic # 9. I bought another one with visibly less hours on it than mine, but it will still need a going thru. Well that's it for now.

Make sure you know how to fall properly when you fall and as to not hurt anyone around you.
Also remember, it's not the fall what hurts, its the sudden stop. !!
