Unless the manufacturer of the plane specifies the bolt be torqued. There certainly are places where bolts need to be torqued into fittings. My Ivo prop is an example of that. That being said; you are in fact the manufacturer of the plane. On engine mounts I would do exactly as you said; torque (the nut) until the slack was taken out of the mount and a cotter pin could be set. Often I have used crows feet for doing this, making torque adjustments for the offset of the crows foot.

The rubber mounts must be compressed such that the bolt is tight on the inner spacer (this limits the amount of compression). The compression of the rubber will add to your torque reading also. I've only installed a couple of enginmes, but in each case did the bolts up tight on the spacer then as required to get the cotter pins in. regards, Grant ----- Original Message ----- From: Speedy11@aol.com Sent: Monday, April 30, 2007 9:03 AM Subject: Engines-List: Engine Lord Mounts I bought the Van's Lord mount kit for my IO-390 (same dimensions as IO-360). For anyone who's installed their engine, to what value did you torque the 7/16 engine mounting bolts? Did you use 475 inch pounds? Did you use coarse thread torque or fine thread?

It's the only way I can figure to torque them. The rubbers are compressed and the spacers seated. I just want to make sure I'm torquing the correct amount. Mahlon, any comment on this?

I think mine were 1/2, works out to 550-600 lb in. 7/16 would be 400-450 lb in. The internal spacers will limit compression. No oil on threads for torque.... > For anyone who's installed their engine, to what value did you torque > the 7/16 engine mounting bolts? > Did you use 475 inch pounds?
