EPICYCLIC 3rd. SPEED GEARBOX REVISED.
X.7310.
X.5310.
X.523.

Herewith we send N. sch. 3161. shewing the arrangement of the oil pump and lubrication jet on the forward part of the above gearbox.

The way shewn of shaping the 2nd. motion shaft so as to lead the oil to the bearings at each end is somewhat experimental and some modification may be required as a result of trial.
