The following procedure is typical of those used for installing a horizontally opposed engine after the accessories are mounted on the engine. Insert engine mounting bolts into the engine mount and slide the shock mounts onto the bolts so that the flat surface of the shock mount is flush with the engine mounting pad.
1. Slide the shock mount spacers onto the engine mounting bolts.
2. Attach a hoist to the lifting eye and lift the engine. Tilt the rear of the engine downward until the magnetos clear the engine mount. Position the mounting lugs of the engine so they align with the engine mount attaching points.
3. Insert an upper mounting bolt into the engine until its threaded end extends one or two threads from the mount itself.
4. Slide a shock mount between the engine mount and the engine.
5. Repeat the procedure described in steps 5 and 6 above for the remaining attachment points.
6. Install the front engine rubber mounts on the bolts and over the forward end of the sleeve; check to see that shock mounts are not binding.
