I tried to install my fixed pitch 2 1/2" prop spacer on the crank hub and it doesn't quite fit. I discovered that of the 6 threaded inserts on the hub (4 long and 2 short) one of the short inserts has a diameter of 0.78" while the other 5 are 0.75". The spacer is sized so it easily slides over each of the 0.75" inserts (all holes equally sized) but will not accept the oversized insert. I tried each of the holes and none will fit the larger insert. Is this supposed to be some type of indexing insert? The crank is an ECi component for an O360 with provisions for a constant speed prop, but set up for fixed pitch. Since this is a hollow crank which can be used with a constant speed prop, does that setup have a larger insert? My Prop is a Sensinech fixed pitch with the 2 1/2" spacer.
