Abstract

No. 14 of the year 1934. Owing to rapid wear of the old pattern valve‐rocker adjusting screw, Part No. 822, on Pobjoy “R” type engines, there is a danger of the valve clearance increasing sufficiently during flight to allow the rocker to foul the valve‐spring cap. New type screws, Part No. 822/1, which are harder and have the striking pad thickened up, must, therefore, be fitted not later than the next top overhaul.
