I was wondering if the y7,8 and z6 crankshaft are all the same? thanks h-t!

 

y7 and y8 are the same
not sure about z6

 

thanks man. just pick up a crank from a z6, i need to do measurements to be sure.

 

I believe I read that the two will work interchangably, but the Z6 has more oil journals.

 

thanks man. so it won't work a z6 crank on a y8 block,rod etc?

D16 and D17 cranks share the same size main bearing diameters.
D16 and D17 rods all have the same major dimensions. The D15 rod is shorter (in general) and has a smaller bearing size, although the wrist pin bore is the same.
D15Z1 and D15B motors have a rod that is the same length as a D16. Other than the rod length, the rest of the bottom end is D15 spec (i.e. rod and crank bearings). D15B has D16 sized rod journals. D15B uses the same p28 rods that the D16z6 does. All other D15s have smaller rod journals.
