Broken cylinder head bolt 912is sport

Really good idea on your part to do that check before a long trip. Can’t imagine the grief if you had engine issues in the middle of the Simpson desert or other similar places. Congrats on some good planning. Also, I’m currently in the UK, returning for most of June then in the USA early July .... flying with S&R in the backcountry. So if you’re passing through on your way to the centre in June, give me a call and if I’m up north building, be really great to see you and Gayle again and brag about my progress !!

Ross,

I'm still trying to understand how the bolt/stud and locating nut works and how adding a new nut would affect it... Can you explain this a little more?

Thanks!

George

I think it would best explained by a Rotax tech George - I am not much good beyond changing the oil - but he stressed on the phone 'Don't put a nut on it and fly!, it will cause damage!" and he did show and explain it when fixing it but in one ear and out the other. I do remember him explaining that the rather long stud/bolt is designed to spread the load evenly over the hole length - however that doesn't answer your Q

cheers

No worries! Just curious.
