I just purchased a 1970 Case 580 and I'm performing my first (of 6 needed) seal replacement. The cylinder I started with is the tilt. I purchased a seal kit and the only parts in the kit for the gland that are associated with the 1 1/2" shaft are 1 seal and 1 wiper (see photo). The old parts included these 2 and also an "O" ring and another seal both of which were down inside the gland. 1) Am I missing parts in my new kit or has there been a change? 2) Also, note the orientation of the seal in the photo. This is how the old seal was in there. This is the opposite of grease seals I have replaced in the past. Is the picture correct or was the old part put in incorrectly? Thanks, Tommy
