Exhaust Pipe Nut Torque

by Bob Yanniello in 912iS Technical Questions 11 months ago

There appears to be conflicting information between the Installation Manual (15 Nm) and the Heavy Maintenance Manual (12 Nm) regarding the proper torque for the exhaust pipe flange nuts. Can someone please clarify this apparent discrepancy?

I've always used the 133 in/lbs.

Most likely an un-caught typo

Thanks, Roger. I’ve been using the more conservative value, but since the IM is 8 years more current than the MMH, I guess it makes more sense to use that value. Thanks again.
