hi Paul,    can you find out what alloy the eshaft is make of?   can it
be chrome plated or nitride? i have been unable to find a shop with
induction hardening equipment in the Denver area yet.  does the
induction hardening strengthen the shaft any appreciable amount or is it
just to slow the journal wear rate.  i checked the shaft with file and
center punch, only the journals are hard, grind off about .010 and it is
much softer.  the rest of the shaft seems to be whatever heat treated
alloy used.  thanks   wyo. walt.

Induction hardening does increase the strength but you are putting
half the average load through the aft journal and flywheel joint
where the highest stresses are.

I have no idea on the alloy. It could also be nitride but I doubt it.

Richard, how did you re harden the e-shaft?
