Is this so? > kk While I consider the Rotax to be the only engine for my planes, I am somewhat disgusted with some of their practises,,,,,,,,,as most anyone who deals with other people usually is. You like some things and dont like other things, but the total is favorable. They installed the seals incorrectly on the early 532s, and changed the shaft diameter during the so called fix, which amounted to turning the seals the correct way. Theye then plugged the only weep hole and now a water leak contaminates the oil due to the seal being single lipped and readily admitting the water/antifreeze solution into the oil portion of the engine. This contaminates the oil portion, which requires changing bearings which requires a total teardown to do so,,,,,,,,,,,,,, I am tired of paying 100 bucks for RV shafts and Im sure others are tired of paying for the teardown as well. There has got to be a good fix for this problem, and I feel Rotax has gone the wrong way plugging the weep hole. While it prolly does make for a cleaner tail group, the internal mess is a lot worse. Keeping the oil where the oil belongs is pretty simple. Keeping the water out of the oil is also simple. Keeping the water seal from leaking under the high pressure is now the problem,,,,,,,,, I run a large radiator and a 4 pound cap. Very few problems with my personnal engine so far,,,,,,,,,,,,but Ive got three or four trade-in engines to rebuild and would lke to experiment with new ways of sealing. -- Mark Smith Tri-State Kite Sales http://www.trikite.com 1121 N Locust St Mt Vernon, IN 47620 mailto:mark@trikite.com |
