Thanks guys, really appreciate you input. I don't know if there is a CAT dealer near me, but there is a John Deere dealer 5 mins away and I remember them having good NLGI grade (2 or 3) Moly grease made for their industrial farm equipment. Maybe I will check that out if I can't find the CAT ultra stuff. Thanks again for all your advice and write ups you have done, they have been very helpful!
