Reply To: 1956 OMC 15HP Crank Seal

Brought this old thread back with an idea to save the crankshaft.  What if I made a sleeve of plain carbon steel not hardened.  Then slipped it onto the shaft and welded just the outer end of the sleeve to the crankshaft?  Maybe just weld three spots 120 degrees apart.  The seal would be running against plain steel.  Wouldn’t the seal wear on that surface for a very long time?  Maybe the welding would soften the hardness of the crankshaft internal splines.  But wouldn’t the splines still wear for a long time?

Any comments/thoughts please.
