Crankshaft question

[Jeff Balazs]

I was reading thru some ad's yesterday and came across one for a 230 crankshaft. There was a notation within the ad saying that it was specifically for a fluid drive equipped truck. I wasn't aware that there was a specific crankshaft for this application. Does anyone know if this is true? And if so what the differences are between this and a standard crankshaft?

Thanks in advance.

the number of holes in the flange for the fluid coupler verse stock clutch

Interesting. I was thinking that this different bolt pattern would occur at the flywheel and only the flywheels would different.

Obviously I never took mine apart.........

Thanks, Jeff

The fluid coupler requires 8-bolts for attachment. There are 4-bolt and 6-bolt crankshafts also, dependent on year and application.

Obviously, an 8-bolt could be used in place of the others, and the others could be drilled.

Thanks for the explanations guy's. Learn something new everyday!

I believe there is also a difference in the pilot bushing. I don't believe one is required for fluid drive but is required for non fluid drive.

while I cannot say 100% that they are the same bush, the fluid coupling crank I have here is prepared for the installation of a bushing....

A related question. Were all the later 230's fitted with an 8 bolt flange? Seems to me I read something ....somewhere about this. But I could be wrong.
