Crankshaft Balanced and Piston Install Begins

Finally got the crankshaft sorted out.  Having destroyed the first one "gaming" the Hines machine and discovering that there are no 60 over bearings for the replacement crankshaft I sourced a third crankshaft and immediately sent it out for professional balancing,


The balance included the disk cover as well.  There was some residual wax and residual dust that had to be removed.

The crank has been laid and the rod clearances measured.




Ring gap was verified and documented.


Rings were installed, and pistons installed.

Care had to be taken with custom pistons manufactured to account for intake and exhaust value movement.  The prior pistons were flat dished and it may be that orientation was not as important.




















Now rod orientation and piston orientation to match intake and exhaust relief is critical.

The heads are being line honed.
