I'm having a problem finding a rear main seal for a V1702-6660 in a Bobcat 743B skid steer. Bobcat shows 2 different rear main seals, but neither of them are correct the engine (I guess it's been re-powered before I got it). Anyways the rear main seal od is 4.000" (101.6 mm), and the diameter of the crankshaft where the seal rides is 3.352" in dia (85.13 mm). I don't have the engine serial number, can't find it anywhere on the engine. Any ideas on a part number for the seal based off the measurements?
