pawoodswalker has not been around for almost 10 years.Hi Pawoodswalker, I to have a Sears 5540 Meat grinder. My friend found it at a garage sale for $1.00 the gears had to be relaced which are standard boston gears and can still be purchased. The lube I use for the gear box and have been for over 30 years is Food grade Lubriplate FGL-2 from the Sausage Maker. If you are ever interested in selling yours let me know
Thanks!
