Here's a word to the wise on gear lube: do your research prior to just putting some in the gearcase. Right at the moment I can't remember the exact name it's called but some of the newest grades of gear lube will actually attack bronze gears and bushings. I think it was something like de-sulphurized and was API Gl-5 spec lub, IIRC API GL4 lube didn't attack bronze parts). Kind of like the DOT3 vs DOT4 brake fluids, may be newer but there can be downsides to it.So much for Sears customer support. I sent them an email requesting the proper fluid to use in the gear case and this is the reply:

Thanks for the inquiry and for being a valued member.
Originally, I think the gearbox had 80W90 gear oil. You can use any axle grease in the gearbox. I prefer White Lithium Grease. It seems to do better in the cold temperatures.
I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.
I was expecting a reply that said XXXX is the recommended fluid/grease and not "I think" and "I prefer".
Due to the temperatures a snow blower operates in I would stick with the 80W90 or 00 grease as actual grease in my opinion is too thick and won't flow. Like Shryp pointed out that it gets pushed to the side. 00 won't do that as it's too fluid.
I do like Mobil 1 synthetic for a lot of lubricating purposes but the gear case isn't one of them. That's my 2 cents.
Just finished replacing an auger shaft spacer. It's about 30 minutes to take off the housing and properly replace the spacer. I read some think the spacers aren't really needed. Looking at it the spacers keep the auger blade flange bushing in place. Without it the bushing could displace, and the auger blade would bang around and make trouble. Do it right, otherwise it will be more expensive to do it over.How do I go about replacing this black plastic spacer on the auger shaft of my Craftsman (247.88830) ?
