LH 4/13/42 1.211.53 Dear F/Lt. Norrington Would this do ? For A.M.O. (E) Marine Craft. Power 100 h.p. Engine. Gudgeon-pin fixing. A batch of defective bolts, gudgeon-pin clamping (Section 13 N Reference 29 7) have been issued by makers. Their defect is that the thread has not V been cut far enough down the shank for the head of the bolt to clamp the split end of the con-rod before bottoming. This allows the slot in the con rrod to work slightly upon each detonation, with the risk of its splitting downward along the centre Of the web. Engine failures have been noted due to this cause. Units are to examine all these 5⁄8" clamping bolts held as spare in Stores, and to rectify any that are defective, by extending the thread. Bolts of this batch may have been used in engines, of serial numbers earlier than 7850 (July 1935). Units are to examine their engines upon this point, during the next top or complete overhaul, and make an entry in the log book when done.
