OK, I can't find any info on this. I cleaned it and packed her full of grease, but she's killer stiff to turn. It won't break or anything, but I guess I overdid it. There's an oil seal to keep lube in and a "filler" (?) hole with a screw plugging it it that ends up close to the top. Should I leave it as is, remove a bunch of the grease, or clean it out and shoot some 90W in the hole?
