[SEL] Petter Gib Key Update - Need Help!!!

[Paul Maples]

I agree with you Larry, I am just very leery of doing this as I once drilled 
out a gib key on a IHC pulley and thought I was drilling dead center but the 
drill had ventured up through the pulley. Also as you can see the end of the 
key is probably 1/4" to 5/16" square but rapidly tapers down as it enters 
the flywheel not giving me much room to keep it in the center. I don't know 
how long the key is as the governor assembly is blocking my view of the back 
of the flywheel area.
