1950 5hp ELTO Sportster - Gearcase Question

[pckeen]

I have stripped down a 1950 5hp ELTO. When I removed the gearcase, which has been stored for years, I looked inside and saw what looked like rust. Do I took the gearcase apart, and, sure enough - there was a layer of rust on everything. I sprayed everything down with fogging oil, then took the prop gear out and used a wire wheel to clean it up. It came clean, but there is lots of pitting on the gear teeth.

Should I just chuck this, or could this be reused?

Second question - the pinion gear is still on the driveshaft - looks like there was something like a cotter pin used to hold it in place. What is the secret to taking the pinion gear off?

I sold a 5hp ELTO to a fellow that lived up north, wonder if this at one time was my motor!?

Regarding the gear, it may provide years more use do you have a pic?

The pinion could be seized on the shaft. There is a technique with a puller, and stacking shims to slowly seperate it, but I would try penetrating oil and heat for now. Been a bit since I have had one of these right apart, I believe it should slide off once the pin is removed.

Thanks - that's what I figured. Here's a couple of pics, but they don't show the pitting between the teeth well.
