I put the exhaust hangers on this weekend (Vetterman exhaust) and, as you all know, had to remove two nuts from two studs on the oil sump.

This is a dumb question, but not having much experience with engines, I think this won't be the last one I'll ask here.

I couldn't find a torque spec in the Lycoming manuals I have (maybe looking in the wrong place)...what should those nuts be torqued to when reinstalling them on the sump?

TIA...

Steve

ETA: I think I found the answer (finally hit the right combination of search terms)...96 in-lb sound right?

Torques are listed on page 1-37 of the table of limits publication SSP-1776.
Good Luck,

I've been trying to find this publication SSP-1776 on the lycoming site and can't find it. I've looked through their publication area and it doesn't seem to be listed. Anyone know where they list this on their site?
