Default New to me McCormick 10-20

Just picked her up this weekend. The previous owner had engine troubles in 1970ish. Had a seized wrist pin in cylinder 3. He sent the head out to be rebuilt. I would assume it has sat since then. I got all the head parts and other parts in a cardboard box! This is my first restoration from the ground up. And first go at rebuilding an engine! I'm sure their will be many questions! Thanks for the help in advanced!

For now I am continuing to tear apart and see what I've got on my hands! Cant wait to hear it running!

Serial number is KC208354 so 1936. Continued the tear down today. Pistons are out. Cylinder walls look decent and all the bearings look decent. (To me anyway I'm rather new to engine work).

It does look good inside there. Quite often these old tractors got new pistons and rigs then taken out of service or religated to lighter work just befor they got retired.

I would say your right. It had some work done then was retired. I'm still glad I took it apart. A couple rings has started to seize although I'm sure they would free up if the engine had ran when I got it.
I took the head apart yesterday as well. There was no lies about the the head being rebuilt. All new seats and one new guide. The head has never been used since it was rebuilt. I can still see the valve lapping ring on the valve. I have anywhere from .005 to .008" clearance from valve stem to guide. I assume this will be more than good enough!

Spent my spare time during the week cleaning the pistons and freeing the stuck rings. Now my questions begin.

I've done lots of reading the last couple weeks on piston/bore/ring clearance ect. Today I got to measuring some of this and I'm wondering what my next steps are?! Bore measures from 4.246 at the bottom to 4.260 at the top. I'm not sure is this excessive wear or not. The piston measures 4.241 at the bottom to 4.232 at the t

I got a set of rings with the tractor so I intend to use them. The ring gap measures .038 to .028 in the part of the bore where they travel. This is also a higher number than I have read about. Also not sure if this is exesive or not. The top 2 ring grooves will also need to be machined and spacers installed as the grooves are V shaped.
As well as far too loose .010 or so.

Any help is appreciated! Or point me in the direction of some more reading material.

Your valve stem clearance is excessive. .002 is about right. Too much clearance will lead to hard starting as you will lose vacuum. This applies especially when hand cranking. Put in new guides and it will be a lot easier to start. Clean up your top ring groove as you planned, it may burn a bit of oil but how hard and long do you plan to work it? CheersDon

Regarding truing the ring grooves.
Get the bottom land cleaned up first as that's the one that seals under compression and is always the most worn.
Don't remove any more material than is absolutely necessary so as not to thin the lands any more than you have to.
Should you wind up using spacers they always go above the rings.

As my research on the engine contiunues so does the the tear down. I got the clutch out (basically wore out) and the engine out!. There was a rather large mouse nest under the clutch! I also got the cam out. For the most part it is okay. 2 of the lobes though are pitted pretty bad. Haven't decided it I will clean them up and call it good or search for another cam.

It ought to be pretty easy and inexpensive to find another cam, but with a little emery cleaning I think that one ought to run that tractor if you're going to be just piddling around.

I will just clean it up. The tractor will only be used for a local show and my own playing around.

Yep, that's pitted worse than ive seen on a good runnable engine like that.
An older collector told me years ago those aren't pits they are standby lubricant retention pores.

Flywheel is off. I stole the puller idea from others on the site here. I would like to pull the crank. Only to replace the gasket on the front of the engine. I've got a couple ideas on making a plate to attach a puller to. But would love to see what others have done.

The front cover did not have a felt on the crank shaft. Is this correct? The rear did.

I also started into the magneto while I wait for some parts to arrive. I'm missing some parts for the impulse. From the rust I would say they have been missing for awhile. I'm holding the farmer fix in the photo as well! Anyone have a source on something like this?

I think all you are missing on the impulse is the pawl that hooks to that spring and slides onto that shaft, I sure have and many others will also if you need one. That farmer wire is hooked to the impulse release hook, you pull that up to time it to the engine by the book. A 10-20 manual will not show that magneto and how to time it unless it is a late manual, otherwise you can use the timing procedure in an F-20 manual for this magneto.

Made my own puller....or pusher.... and pressed the crank out from the front. Then pulled the bearings. The front is is very rough. The rear is ok.

I've been doing some reading on electrolysis as well. I figured why not try it. It looks a little mad scientist but worked very well! I've attached a before and after of the timing cover. It took all the paint and oil and dirt off! You can clearly see the water line of where the part wasn't submerged.

Summer has slowed me down. But I did find some time to clean up and polish the crank. Hopefully get it pressed back in place this weekend!
