I am rebuiling an IO360-A1B6 for my RV7A. It had 800hrs since last overhaul.
Questions:
1 -Can I reuse the Thrubolts
2 - How can I tell if I need an oversized bolt, I have not been able to find what the fit should be.

Not called out specifically - ask Lycoming if they classify them as "stressed Bolts"

http://www.lycoming.com/Portals/0/t...Overhaul and During Repair or Maintenance.pdf

? Stressed bolts and fasteners, such as:
? Stationary drive gear bolts (reduction gear)
? Camshaft gear attaching bolts
? Connecting rod bolts and nuts
? Crankshaft flange bolts
? Crankshaft gear bolt
