| -2- (a) Temperature of oil draining from sump. (b) Temperature oil in pipe between the pump and sump. (c) Temperature of oil in pipe between sump and engine filter. (d) Temperature in engine filter case. 2nd. Series. With test bed cooler in circuit. With suction oil controlled to 90°C. check the following temperatures:- (a) Temp. of oil draining from sump. (b) Temp of oil in pipe between the pump and the sump. (c) Temp./oil in outlet pipe from the sump taken as near to the sump as possible. (d) By use of external test bed cooler control the oil temperature to 70°C. as measured in the engine filter case. When the temperatures are stabilised in the above 1st. and 2nd. series check the oil flowing from the sump by means of measure and stop watch. (5) Investigation of movement/oil level indicator when running. B.17 Unit. Carry out running on Packard weight crankshaft in accordance with the previous memo. C.17 unit. Following B.17 fit this unit on the bed and check heat flow to oil in the same manner as carried out on the Wraith. continued | ||
