Case 580CK swing cylinder rebuild

Started the rebuild process of the swing cylinders today. My biggest fear was that I wouldn't be able to break the 1-7/8" bolt on the back of the rods. Luckily with a 3' cheater bar and much effort they broke loose. Tomorrow I plan on inserting the o rings and seals. Will have to do a good flush as the fluid was milky and gritty.
