Brief Description:  Install Engine Mount Frame

I installed the engine mount, mostly to get it off the floor so i wouldn't be tripping over it. The firewall has pre drilled holes at four corners, but they dont necessarily match the frame exactly. You kind of need to find a best fit, and final drill the holes to 3/8" (final size) with the frame in place.

I was able to drill the first three holes to 3/8" in their original location but the fourth hole was off towards the side of the hole in the bracket. So, with the other three torqued down, i drilled 3/8" through the frame and firewall toegether. There are also two holes at the bottom of the engine mount near the landing gear support that are not pre-drilled, so i drilled these to 3/8" through the frame as well.

Correct torque for an AN6 bolt is 160-190 In-lbs. I torqued these to 175, then continued to tighten the rotation until the next castle nut flute aligned with the cotter pin hole.
