Looking to see who can balance a cmb 21 crank. Any suggestions?
As Scott apparently is no longer balancing cranks. Does anybody have a suggestion who they would recommend balance a CMB VAC 45? Scott did my original and it is awesome.
Carbide drill and reamer.Terry, great question. I did not check yet. As Scott had done so many that worked I just had him take care of it. Now that he is no longer doing it I will have to measure the difference between the one he did and my stock crank I need done. I only have jeweled balancer at this time. Ill let you know after I come up with a way to check it. After I find that out how the heck do you drill a hardened crank and not damage it?

The best counter weight for the 45's is a two slug add. Slugs are .200" to .205" in diameter. This balances motor to 51.2% and is very good.As Scott apparently is no longer balancing cranks.

Just curious, what size slug(s) did he use? Did you check the amount of weight the crank would offset after it was slugged?
I checked and the crank would balance about 5.15 g or 26% of the total recip. weight. (CMB 21 shown)
