Default Locating No 1 Crankpin
Need to locate number 1 crankpin on an assembled engine. My assumption (!) is that it would be the pin on top with the # 1 cyl at tdc. But not wanting to take this thing back apart and relocate bushings, I'm humbly asking for some reassurance. Am I correct?

Thanks!

Bryan

That is correct.

And the "A" bushing only fits in the big hole... :/

Thanks Bob

Confusing because with #1 on TDC you'd have to rotate the diagram 90 deg. to the left. Make sense?

Yea, I see that. Maybe I'm vaguely recalling reading somewhere about it being 90 off as it's making a little sense. I guess, regardless, the A bushing has to go where it goes. Still trying to figure out how I got this this miss-clocked years ago with the number 1 hole being bigger... maybe I mirrored the bushing installation.
