Now I tapped the camshaft pin out with a 3/8" bolt:

Noted that there were two shims on the end of that shaft. I haven't measured them, but I see from the parts diagram that there are supposed to be a .005 and a .010 there:
.

Pulled the tappets and marked the intake in a separate bag, per the manual:

Now the governor assembly. Unscrew this pin:
.
.
Governor gear fell free at this point:

Remove the rest of the assembly. The shaft comes out from the inside after it's all disassembled:
.
.

Removed this seal from the side opposite of the bearing plate:
.

And I was able to remove the bearings by using the 2" round plug of wood that I had left over from building my steering wheel puller. I put it in place and tapped the bearings out:
.
.
I haven't gotten the one on the bearing plate side out yet. My piece of wood can't get in there. So maybe I'll need a bearing puller, unless I can figure something else out.
Here's a shot of the crank shaft. You can see there's been some grinding done. I dunno what that means yet:
.
And that's it! We're down to a big cast iron block and a bunch of parts. I took it in to be machined today. I'll be interested to see where that bore is, since I know this thing's been broken down before but there's no marking on the piston.
Also, to repeat that the balancing gears were not there. Someone took them out.
(Edit 7/30/11 - I was mistaken all along, as Matt pointed out in several posts where I thought the engine had been pulled out before. The machinist said the bore was off about a thousandth or so. Not all of the Kolhers had balance gears, so it's likely this 341 never had them)
Once I get some info from the machinist, I'll buy a rebuild kit.
LOOOOOONNNNG post! It took me a long time to put this together, so I hope it helps someone!
