| To BY.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Gy. Y5360 Hs{Lord Ernest Hives - Chair}/Gy1/LG13.5.29. This is to confirm that we advise fitting a non-return type of gun nipple to the axles on 20 HP. and 40/50 HP. Owing to the addition of reservoirs to these axix axles for the conservation of oil pressure, we find the standard nipples will not maintain an oil-tight joint. The non-return valve type of nipple should overcome this fault. Hs{Lord Ernest Hives - Chair}/P.Gaye. | ||
