Title: 73 400 crank
Post by: hampster on January 06, 2010, 09:49:02 pm

Hi,

Just pulled apart my second 400 bottom end for parts to finish my first 400 and the crank i was going to use has had water sitting in the crank and it has got under the bearing position and has rusted it past repair, dam***
So has any one in cz land have a 73 400 crank for sale or i can swap a fully rebuilt 400 70 -72 style crank.

Thanks Chris.

I thought 73" has flycut weights versus 71" full circle ????

Thats correct about the full circle versus cutouts but would be pretty sure that they would be interchangeable

That's right but they have a different final drive with the full circle being a taper and the pork chop being a key way.
