PL.280 Synchromesh.

This shows the splines, dog teeth and cam faces to a large scale. We have copied the latest B.V. baulking characteristics (there is not an up to date B.V. scheme showing this).

We have a new way of pegging the 3rd. speed over-run thrust washers, the peg is retained when the 3rd. and 4th. sliding piece is in position.
