This was a big milestone for me. It essentially marks the transition to the "homestretch" for me. With my fine HFT engine hoist and assistance from a friend, the engine mounted fairly easily. I applied Molycote (DC-4) lube to the engine mount rubber before installing, which eased getting them into place and allowed a good seat. I installed the mount side pads with bolts for all four holes first, and then fastened the lower mounts first, then put a touch of lift on the engine from the front making the upper mounts a simple bolting job.

The drawings I have show using an AN7-26 bolt, which has a castle nut and cotter pin, but the hardware that came with the kit from Van's has AN7-21A with a metal locking nut. The torque spec is 40 ft-lbs, and the nuts have 3 ft-lbs prevailing torque (drag), so I torqued all four mounts to 43 ft-lbs.

It's starting to look like an airplane.
