I got the crankshaft separated from the lower half of the crankcase today.
The steel tube attached to the bottom of the crankshaft was too big OD
to slide thru the crankcase bushing, so it had to come off. I lucked out
eventually, seeing how I did not know how it was made or put together.
What finally made it come apart was heating the tube near the joint,
then tapping on the inner drive shaft with a brass punch. I was suprised
to see that the long "tang" was part of the crankshaft!
Also was able to remove the brass drive shaft housing on the lower unit,
but that still doesn’t help me with getting the prop shaft and gears out
of the case. Not sure if the drive shaft is suppose to float free in the
drive gear, or is magically attached to the gear some how.
I put the driveshaft in the vise, and tapped on the gear case with a wood
block and hammer to see if the driveshaft would pull out of the gear,
but no movement noticed. Trying very hard NOT to break anything.
Ideas?
The gears look to be in good shape, but thought it would be best to have
an empty gear case when it came time to attach a new skeg, which
I "zero" ideas how to best do on this one!
