Title: m47 crank
Post by: nickmpower on September 12, 2006, 07:39:06 PM

I still need to call MM and decide what i am going to do for pistons/rods, but here is the crank!

the first pic shows the stock an m47 crank side by side

the second pic shows that the pully (and sprocket) wont fit with out the crank being shaved. it should also be noted that the stock bolt is too small. Im searching for an m18x120mm bolt if anyone knows where i could find one

Awesome!

What part of the crank needs to be shaved? How much was the crank?

Call a business in California called "Global Metrics". They carry ANY metric hardware you can think of. If you can't get it there, you're gonna have a hard time finding it anywhere else. Also check real OEM to see if that crank has a matching bolt with a part #.

the crank was like 765 (with like 30 added for shipping from germany i guess) brand new. with crank AND rod bearings.

the part that needs to be shaved is the diameter of the front shaft so the sprocket and pully holder will fit over it (its just setting on top now).

yeah i got an extra key to. Is it just that an additional one needs to be added? it looks like the crank sprocket would just barely sit on it


I got the crank from BMA, PN 11212247514
