have a husqvarna snowblower and in doing a complete overhaul on the thing I pulled the worm gearcase apart to inspect and relube. A link to pics of the gearcase here:

it's a steel worm gear on the input which turns a brass straight cut gear to rotate the output shafts (which turn the big augers). Being 10+ years old, good thing I did what i did because there was a huge lack of grease and a lot of yellow shavings in there.
Got everything back together, and decided to go with lucas red'n'tacky grease based on their description of the product, it was available and economical.

My biggest concern is I've lost at least 5 oz of oil, completely liquid, out of my grease gun. Laying on my bench, I'll have a foot in diamter puddle of oil from my grease gun every week. This stuff bleeds like crazy. I know grease is supposed to bleed a little, but how much is too much?
I tapped in a zerk so I can easily grease the gear case, and it is full of grease. When I first rotated the augers after filling the gearcase, I got moderate grease leakage out the input shaft seal, pulled the zerk and had about a 3-4" goober of grease 1/4" in diameter come out. Replaced the zerk, so now the gearcase should not be overfilled or overpressurized with grease, and I still get moderate seepage and bleeding of grease and oil. And the seals are good! Should I be concerned about the grease?
