I was on the fourth compressor in nine years and about 600 cycles when my RAM750+ screeched to a halt a week ago. My first thoughts were "not another compressor" gone but this time the rear bearing had failed catastrophically and now the motor is probably not worthwhile rebuilding.

The characteristics of the three failures my Ram compressors had were basically identical except the part of the vane that failed on #1 did not break off. Also interesting to note that the failures happened at approx. 180/360/540 cycles indicating fatigue as the most likely culprit. We used to joke that the next one was expected at about 720 cycles but now I don't think we are going to get there.

Had a great ride with the Ram and all happened on the same Kangaroo.
