I guess when it rains it pours...... 2 weeks ago I had to remove the radiator and have it flushed out because it was running hot on me. Now last week I noticed hydraulic oil leaking out below the turn table between the tracks. I brought it home this weekend and tore it apart looking for a reason why. It turned out the swing motor is leaking oil right above the gear ( the best I can tell )..... What is a normal fix fort this? Is it possible to replace the seal, or does the whole swing motor need replacing, or rebuilding? In the 7 years I've owned this, I've never had a single problem and now it seems to be piling up on me... RussB
