Print this Lycoming chart for reference. The sump bolts are 1/4 inch.

Thanks Gil.

Yes, it's definitely worth down loading the 191 pages, but printing and posting on the wall the single page 190 is good for workshop reference.

Thanks for the updated link, the table now has a tolerance in the nut/bolt torques and seems to allow about 10% more torque at the high end.

Here is the updated single page for reference.
