That looks like that's only one of several mods made to that crank.

Tim: That is the nicest B31 crank I have ever seen. The originals are pretty crude.

Without frequent roadside repairs there is no fun in riding!

Gordo,

This is a modified M20 timing shaft in my Jabsa engine for oil seal in timing cover.
As M20 has 2 main bearings on timing side, shaft is longer than B31/33/Goldies and so can be turned back to give the oil feed tit integral with timing shaft.

This is the crank.
