Luca Posted September 9, 2017 Report Share Posted September 9, 2017 Hi, I'm an owner of a Pipistrel Taurus, 150 hours of engine Flight ( belt changed at 100 hr ) 3 weeks ago I've had an engine failure. Rotax mechanic's found a seize up bearing and an extreme belt tension. Has anyone get the same problem ? Has anyone measured the belt tension ? Thank you Quote Link to comment Share on other sites More sharing options...
pdrav8r Posted September 9, 2017 Report Share Posted September 9, 2017 That is really strange for at least 2 reasons: 1) the belt tensioners are not adjustable, 2) the crankshaft & bearings of the Rotax 503 are very strong. What oil are you using? Are you mixing it 50:1? Have you noticed unusual engine temperatures? Quote Link to comment Share on other sites More sharing options...
Luca Posted September 10, 2017 Author Report Share Posted September 10, 2017 Thank you, pdrav8r Yes,mechanic also said me that he never have seen a damage like that in 40 Years I always use suggested oil ( don't remember the name ) at 2% misture No unusual temperatures, only sudden propeller block Br Quote Link to comment Share on other sites More sharing options...
