At some point somebody dimpled the flywheels in my '74 shovel, I assume to balance it. I can't find anything in the FSM or online about crank runout for a shovel, it all seems to be Evos and newer. Is there a spec for shovels? I measured mine at the pinion shaft at .0065".

Thanks. I actually have a very similar manual, but somehow glossed over that. Just so I'm clear, is "Runout (shaft at flywheel)" at the pinion shaft where I measured it? Can I measure "Runout (flywheels at rim)" with the flywheels in the case and a dial indicator through the bore, or is that something different?

It's funny you mention the bushing, because that is something else I ran across--the cam bushing is sitting probably 1/8" proud of the boss, and the pinion bushing is at least that much low. Could the shaft being out of true cause it to work down, or was it installed poorly? I've never seen or heard this engine run, so I can't comment on how it sounds or any of that.

Can somebody help me understand what I'm missing here? Upon closer inspection I realized that even the picture in my manual of the gearcase cover bushings looks like what I posted, but clearly I don't understand what they mean by pressing them in flush with/against the cover boss.

Thanks for all the pointers, guys. At this point I'm going to let sleeping dogs lie and leave the bushings (and flywheels) alone unless things sound like they're going to fall apart when I finally get it going.
