This Grease Seal provides a barrier between the grease in the gearbox and the external splined drive shaft that drives the auger. It is located within the front flange of the gearbox. If you see grease in the hub of the grinder where the grinding head attaches, this seal may need to be replaced. This part works on our entire line of BigBite® Grinders, model # 777, 777a, 1777, 779, 779a, 1779, 780, 780a, 1780, 781, 781a, 1781, 782, 782a, 1782. If you have a 700 or 700a series BigBite® Grinder we would also recommend getting a replacement pad gasket SKU 01025004 or SKU 01025003 (link to these SKUS) as well as they commonly need to be replaced when opening the gearbox. Replacing the gearbox grease is also recommended when opening the gearbox. SKU 01159001
