These two drive cases were obviously neglected. They were pretty corroded and pitted. Except for the damaged bearings due to low oil and the leaky seals, the insides looked like a recent rebuild with all new bearings and the gears had no sign of wear. I sanded the chipped up skegs smooth and rounded them out. If the skegs get any shorter on these units, I'll have to weld on new ones.
