I can see greasing the gears but why the opposite side?

Good question.  I recall as kids, doing stuff like this.  One of my buddies oiled his American Flyer loco with Wesson cooking oil.  For some reason, it wouldn't run after that.  I wonder why.....

Dan:

     I bought an old Lionel 1862 General like that, only it was oil that was overused. The thing was dripping with oil. I imagined that each time the engine slowed down, the previous owner must have thought- Just add more oil!

    In your case the previous owner must have thought each time the GG-1 slowed down- Just add more grease!

Interesting! that looks like the "grease" I had to pick out of my Weaver models VO1000 to get it to run!

Same here...   But in my case it was a factory problem re the VO's that Gary (Weaver tech) told me about.  I  purchased a VO-1000 (ATSF) still sealed just a couple months before Gary left Weaver and they closed up shop.  Considering when that run of VO's was made, this one had been sleeping for a l-o-n-g time.  When I tried a test run it wouldn't move, but you could hear the motor hum in its struggle to turn.

I called Gary, explained what I had, and he immediately pointed to the old gear lube....needed to be cleaned out/replaced.  Within the hour she was running as smoothly as silk.  

It was a similar situation to the China lube that Lionel put into a late run of gantry cranes.  Talk about a gummy, gloppy mess in that gearbox!!

But that GG1!........

 

One other related point.  I have two "G" scale Bachmann Davenports.  George Schreyer, on his website, recommends loading the worm gear/axle gear box, with extra lubricant.  These locos have a tendency to jerk when running downhill.  I think the jerking has something to do with too tight a fit between the worm and axle gears.  

I agree with Don, the grease looks like the stuff Lionel was using when that GG-1 was made. It was also included in their maintenance kits.

I have run across a few New, old stock motorized units in which that grease had hardened and took a bit of work to remove.

Whether the grease stays soft or hardens is probably largely related to storage conditions.
The trains with hardened grease were fine in every other respect, as were the boxes.
