I wouldn't worry about using grease in the gearbox, the old Gilson have a 90 degree GB that drives the transaxle and they are packed with grease, had a 1972 G16 GB opened this past spring cleaned out the old grease and repacked it. The GB and gears looked like new I would be concerned about 80/90 leaking but the 00 (cornhead grease would not leak.
Sickle bar mower refurbish
So I got these 2 mowers a few weeks ago, my ad on Craigslist really payed off. I got the 2 mowers, The Custom, the ST12, a buncha mule drives and random Sears parts and 3 3 point hitches for $400.
Model # 842.260020
Serial # 86260 and 97522
Neither of them are in working order but both are complete. As you can see in the first 2 pictures, one of them is severely twisted and broken but it's actually in better shape as far as rust goes. So all it's good parts will be switched to the other one.

The shaft and mounting assembly is much better on the twisted one, so it will be switched along with the rest of the pulleys.

Everything is coming apart surprisingly easy. This pulley came off with minimal effort with a pulley puller.

Took the arm off that makes the knives go back and forth off to make sure its crankshaft isn't frozen. It's not.

I assumed the mule drive gearbox's would have oil in them since they have a drain plug, but they don't. The grease? is hardened into a brick. Are they suppose to have gear oil in them?
