I have recently aquired a 2655 Oliver and I am sure it is in need of replacement of all oils in transmission, differentials, drop box and hydraulics. I cannot find what the proper oils are. The owners manual only lists Oliver part numbers and recommends going to an Oliver dealer to get the proper oils. I am sure there are suitable oils, but I don't know what oil weights would be apropriate. Anyone got any suggestions?
                       Thanks,
                           Cal
