| EXCESSIVE WEAR ON SPIGOT LOC/N OF LT C/B HOUSING TO GOVERNOR CASE - CAUSED .008" VARIATION IN C/B GAP ON 49 GB. ALL REPAIR CARS FOR O/H ARE AFFECTED. HARDENED STEEL BUSH RECOMMENDED BY HS.{Lord Ernest Hives - Chair} ORIGINAL WHY HAS NOT HM{Capt. W. Hallam - Head Repairs} PUT THIS FORWARD? HS{Lord Ernest Hives - Chair}8/LG23.11.20. To: [redacted] c. to SS.{S. Smith} c. to [redacted] c. to [redacted] c. to [redacted] c. to EFC. X 1819. BATTERY IGNITION - 40/50 CHASSIS. X 3762 We find on the present standard 40/50 Car that the spigot which locates the low tension contact breaker to the Governor Case wears badly. We find on 49-GB Car that this spigot has worn so much that the gap between the contact breaker points can be varied .008" by the slack. On all Repair Cars which come in for overhaul, this complaint is noticed. At present the spigot formed on the Governor Case is aluminium. We recommend that we should fit a hardened steel bush to run in connection with the bronze contact breaker casing. [STAMP: NOV 34 RECEIVED] Hs.{Lord Ernest Hives - Chair} V.{VIENNA} | ||
