hihosland Posted March 2, 2007 Share Posted March 2, 2007 What is the expected life of the springs that secure the components in a Rotax 912? And what will have an effect on that life? many thanks for thoughts Davidh Link to comment Share on other sites More sharing options...
Guest pelorus32 Posted March 2, 2007 Share Posted March 2, 2007 G'day, all I know on the subject is that I found and we replaced a broken spring during a preflight the other day. If I recall correctly the spring had done 400 hours. It broke where the "apex" of the hook on one end had worn on the anchor point on the exhaust pipe. I understand that filling them with silicone helps extend their life as it stops them vibrating. Regards Mike Link to comment Share on other sites More sharing options...
Guest micgrace Posted March 2, 2007 Share Posted March 2, 2007 Hi filling the springs (along the side in a couple of "strips" ) with silicone is a common practice used on Rotax 2 strokes where vibration is very high at idle and off. I suppose it's valid for a 912 although I can't recall any recommendation for such apart from safetying. Micgrace Link to comment Share on other sites More sharing options...
hihosland Posted March 2, 2007 Author Share Posted March 2, 2007 Mine broke at 225 hours in two years. It broke where the "hook" joined the actual coiled spring part. No silicone filling. Davidh Link to comment Share on other sites More sharing options...
