Will you please have the drawings of the outer member (G.79872) and the sliding piece (G.79964) altered to the modifications shown on Ex.7967/8 and 8076. The two rows of plungers are to conform to 25HP practice. We have not tested a box with one row. The additional oil holes are to prevent oil trapping while changing gear.
