Default Lycoming O-360 ring gear

: did you count your ring gear teeth? I think the direct-drive starter
: gears were a little larger in diameter.

: sorry I don't have ready access to prestolite starter drives any more,
: the stuff I allegedly maintain nowadays read RPM in % N1 & N2.

I did this weekend and verified it's 149. The paperwork in the logbook says
the Skytec starter is a 149-12LS. Guess that means I put a 149 back on... just wish I
knew why it wore out in the first place. Maybe the old Prestolite was the wrong one
and wore it out prematurely... it *did* have a cracked mounting flange.

: : I'm sure you are aware that only the outer portion (the "gear") needs
: : to be replaced, not the entire support assembly.
:
: Yes... looks like the price on it tends to run about $130-$150

: heh. or twice that if you drop in on the support upside down, or fail
: to get it seated all the way. BTDT

Ooops. Guess I'll need to be extra-careful putting it on. How hot of an oven
is necessary? I dont' want to kill any heat treating on it, but I don't what to have
troubles (or lack of time) getting it on either.
