What way did you guys have your motor balanced??? Like was it an external crank, with netural balance flywheel?, and an external dampener? or was everything externally balanced...??? I am asking because I had my motor internally balanced and it seems the crank broke on me....and I think it was because of the way I had it balanced.

 

Mine is externally balanced. Your balancing didn't have anything at all to do with the crank breaking.

 

Ditto on both accounts

 

the crank probably had a small crack, whick turned into a big crack

 

Where did it break; where they always do, at one end (most often the front end) of the pin for the #1 & #2 rods?

If so, balancing had NOTHING WHATSOEVER to do with it. About the only thing that can stop that, is using a better crank damper than stock. NOT a Fluidamper or a Rattler or a chinesium one like a CAT; the only one that's anywhere near dependably effective is the ATI.

 

"pin" for the #1 and #2 rods? What pin is that?

 

The round thing the rods are bolted to.

 

I would be safe calling that the cranks front rod journal eh? I just want a mental picture of this.

 

Yes, the front rod journal.

 

oh ok well that gives me reasurance that it wasn't because I went internally balanced...I was just trying to figure out why it broke, but you guys cleared that right up so for your help and I only hope that my luck gets better this next time around. lol

 

Yeah my little bro keeps a piece of one of my old 400 cranks, that broke off right there.... it sits on his coffee table, looking like a cast-iron pancake with a wart, just the front "throw" of that #1 journal, the counterweight, and the snout.... like I said, pretty typical. I was running a stock damper on that motor, too, just like you I guess.

 

Here's my past two advetures
