This is a video of the bearings of the broken piston rod that was still on the crank. I'll be cleaning up the 82 crank to see if it's usable.

journals clean? no bearing metal smeared on them? could interfere with the reading unless they are clean.

I haven't checked it out yet. I've been assigned a roofing project before I head back to louisiana. But I definately will pay close attention to the journals...thanks

Jersey, I would not discount the '81 crank over the '82 crank just yet. I would just check for roundness. It might be fine!

10-4, I'll check both as best I can and post the results and get your opinion and feed back before I move on either one. Thanks

ok, first I've been talking about mic-ing the crank, but I don't have a mic, I have a digital caliper. I did get the plasti-guage, but I'm trying to see if 1 of the 2 donor cranks are even a candidate.

The original crank is stamped 2F.......letter "A" is engraved on opposite side
the 82 crank is stamped 1A......letter "B" is engraved on opposite side
the 81 crank is stamped Y1.....nothing is engraved on opposite side


original case is SC02E/ 2211608
82 case id SC02E/ 2203284
81 case is SC02E/ 2129493

Piston 1 is stamped 2D
Piston 2 is stamped 2D
Piston 3 is stamped 2D
Piston 4 is stamped 3D

Main cap 1 is stamped V8
cap 2 is stamped V2
cap 3 is stamped V8

I have a question for those that might know:

Is it normal to find a crank that has an engraving on it, IF it's said that no one has ever been inside the engine. Not a stamp, but an engraving? I've never been inside of any motorcycle engine, but this just screams that someone has been inside of this thing before.

I have seen engravings in these engines.

Ok, so the engravings could have come from the factory? Are you saying that the engravings doesn't mean that the case was previously split after it was originally assembled?

The engravings on the crank and rods are the bearing codes, etched at the factory. See post #64 for the bearing selection charts. 1, 2, and 3 on the crank are the three main journal codes, A, B, and C on the crank are the four rod journal codes. The rods will have 1, 2, or 3 for their bearing codes, and letters for the rod weight codes. These codes will all be engraved, not stamped or molded. On the front of the right-hand case will be I, II, or III for the three main bearing support codes.

As an example, my '83 were all 2's, B's, and II's, and according to the charts, are all brown bearing codes. There is a dab of paint on the bearing shells.
