Hi Rusty,



i’m a bit confused now. Is the problem part the eccentric crank that connects to the bit on the wheel or is it the bit that is attached to the wheel?

If it is the bit that is attached to the wheel only then that is what I was thinking about by getting the front wheel assembly which is known to be good and just pull the crank pin from the wheel which is attached to the engine still and then put on the front spare crank pin, that way you are not having to mess with too much stripping down and any quartering.

The issue is with the driver.  There are slots on the #3 drivers to accept the keys on the crankpin.  The slots are in different locations on the right side driver vs. the left side driver.

This drawing shows the current issue:

The drawing shows the correct locations for each:

It is the slot on the drive wheel that determines the angle of the crankpin.  It why the drive wheel itself would have to be replaced with a 'Left side" and of course, quartered properly.

Rusty
