1708. My 8591, 9191, 40, 503. Further and more specific reports from submarines, Division Four, show following defects engines K-1, K-2, K-6: Cams and rollers, handling gears, wrist pins and bushings, vertical cam shafts, fuel and lubricating pumps, badly worn. In general lost motion in all moving parts. Spray and scavenger valves and air compressor valves in poor condition. Batteries of E-1 in such bad condition that it is not considered safe to operate submerged. Requisitions for spareparts at estimated cost of about $400,000 have been forwarded to Bureau of Steam Engineering. K-2 is now at Lisbon for docking and overhaul of hull. Arrangements have also been made for docking other three vessels. In view of length of time probably required for supplying and shipping engine and battery spares necessary for placing these boats in good operating condition, I renew my recommendation that these vessels be replaced by new submarines, and that they be sent home for necessary repairs. 22324 1708
