Re: SSP-1776-3 Lycoming Table Of Limits and Torque Value Recommendations
Anyone working on their airplane should have page 1-42 & 1-43 close to their tool box.
Of course you all have a calibrated torque wrench.i:lol:

Did you notice that the exhaust nut torque is back on there?

I thought it had always been there just hard to find. I could not find the torque value for exhaust port nuts which previously was 160 to 180 in-lbs to attach the exhaust stacks to the cylinder
Figure 906 on page 1-38: 40 in-lbs. on the exhaust port studs.

For information to others the exhaust stud torque is figure #906 on page 1-35. 40 inch-pounds minimum.
Actually that is the exhaust stud driving torque. The next line is "Nuts to Attach Exhaust Stacks to Cylinder Head 160-180 in. lbs. That was not in my old table of limits but I had penciled it in from something you found several years ago.
Re: SSP-1776-3 Lycoming Table Of Limits and Torque Value Recommendations
OK page 4-35 lists the exhaust flange nuts as 160 to 180 inch-lbs.

Page 4-35 is for vertical engines. I wonder what the difference is or did they forget to list this value in the first section?
Re: SSP-1776-3 Lycoming Table Of Limits and Torque Value Recommendations
That confused me also, Steve set me straight. too. That page shows the difference between the vertical engines and the others.
look at the line for the exhaust nuts, there is no engine model listed, it says ALL. Look at post #5 above with the line copied from the SB.

Ahhh, I see now. Thanks for pointing that out. That's a tough one to find.
