| 800 1044 To By. {R.W. Bailey - Chief Engineer} from Rm. {William Robotham - Chief Engineer} c. Da. {Bernard Day - Chassis Design} c. By {R.W. Bailey - Chief Engineer} /Jnr. {Charles L. Jenner} Rm. {William Robotham - Chief Engineer} 1/AP.30.8.37 PHOENIX ENGINE UNIT Replying to By {R.W. Bailey - Chief Engineer} /Jnr. {Charles L. Jenner} 1/G.20.8.37 our views are as follows:- (2) It is not worth saving .75 on the length of the engine if it means departing from the standard length of Bentley crankshaft. (3) We have put the question of a joint on the crankshaft centre line up to RHC. {R. H. Coverley - Production Engineer} If we do utilise this construction, we shall have to ensure the attachment of the gearbox to the engine is very solid. Vauxhalls have run into trouble due to this joint causing flywheel vibration. (4) We do not think that on a six cylinder crankshaft we can depart from drilled pins. (6) We are going right ahead with tests on an oil pump having a suction lift similar to that projected on Phoenix. We shall do some of the tests in the cold chamber. (8) We are carrying out tests deleting the spring drive from the timing gears. (10) Do not see that four bearing camshaft should not be satisfactory. (17) We are certain that we have got to make timing gears so that we do not have to look at them, and think it will be sufficient if these can be got out by taking the engine out of the chassis. Water Pump If we cannot accept a belt driven dynamo we think we should not accept a belt driven water pump. Oil Level Gauge We shall have to try one of Smith's instruments. continued | ||
