Getting themotor mount bolts torqued correctly has been another one of those nagging items that I've been procrastinating about. These were previously torqued without lubricant, and after reading an EAA artticle (or Kitplanes) I realized these may have been overtorqued, or at least not optimally torqued. An engine mount bolt giving way under power is notsomething I want to experience, so I had always known this needed to be done correctly at some point and I needed to use new hardware in case I had stretched the exisiting bolts. It's not that I don't have the right equipment to do this; it's that removing each bolt from the motor mount requires the removal of 4 AN3 bolts from the attach bracket on the cabin side.
These are all AN5-23 bolts, except for one AN5-24 on the upper left mount point (pilot side). They were torqued to about 125 lb-in.
