The extra hole is to allow it to be turned 90 degrees, for when the ring
gear is worn and a replacement is not readily available. A hold-over from
TR2 and TR3, where the ring gear was pressed on. It's mentioned in the
workshop manual, page 1-123 for the TR4 version.
There is a TDC mark that should be moved, if you use the alternate dowel
hole.
