In reviewing both the ROTAX 912iS installation manual and the ROTAX 912iS Heavy Maintenance Manual, I find two different callouts for the torque of the M8 locknuts for the exhaust pipe attachment.

Page 5 of Chapter 78-00-00 of the heavy maintenance  manual specifies a 133 inch pound requirement for the M8 locknuts.

Page 7 of Chapter 78-00-00 of the installation manual specifies 106.8 inch pounds.

I'm guessing 133-inch pound is the correct one but would like confirmation.
