EPICYCLIC 3rd. SPEED GEARBOX (REVISED) - OIL PUMP.

On looking further into the assembly of this box we think we should like to shorten the pump as indicated on N. scheme 3171. herewith, enabling the rocker shaft for the vacuum operation to be passed between the pump and the epicyclic gear with freedom.
