The beam has been tried in a number of locations but its present location, across the front end of the custom oil pan (which is shaped to accept it), is ideal. The beam carries most of the engine load and the low position of the Barry Mounts helps keep motor mounts tubes well away from conflict with the exhaust. It is secured to the engine by eight 6mm pan bolts.

The use of thread inserts (Helicoil or Time-serts) in the aluminum pan bolt holes is highly recommended for all rotary conversions and is a required step in engine preparation for S-beam engine mounts.

There is another “beam” in most S-beam engine mounts. It is the Rear Beam and it carries the lighter loads at the rear of the engine. Like the S-beam, it creates a wider engine mount that provides more room for the exhaust. It is attached to the engine with a bracket welded to the rear face of the pan. The bracket is extended to the pan flange and welded to it. All vertical loads are carried into the the engine and not borne by the pan at all.
