| To RM{William Robotham - Chief Engineer} X7060 10/7/28 Re Phantom Push Rods. We have tested two push rods fitted with cups and drilled so as to allow the oil to be fed inside the rod with a view of heating up the rod quicker. The tests show that this method has no advantage over the present system the valve clearances in both instances remaining the same. for a definite period. G.H.Hancock. | ||
