L2 lube is a special 90W AGMA 5 gear oil, not grease. I would not assume just because there is grease in the gearcase that it should take grease. After all, there were nails for shear pins right? I believe there was a liquid #00 grease used at one time, as well as  lithium complex #2 EP-rated grease. For worm gearcases make sure you get an EP rated grease and not the standard stuff. I'll check your model for you tomorrow to see what lube it takes. A serial number would really help out for this. It should be six digits long right below the model #.

The parts manual probably calls out the shaft/gear combo. It's likely you can get the gear alone, but not recommended. If the current worm shaft were damaged you could ruin the replacement gear. If you re-use the shaft, be sure it is perfectly straight and make sure there's no damage to the worm profile (most times the damage, typical bent shafts, is not easy to see without V-blocks and a height gauge). The gears are made from manganese silicide bronze with a partical hardness of Rc70 (micro hardness, not macro). Pretty hard, but a damaged worm shaft can tear it up in no time.
