- 3 - The bijur lubrication to the servo should be cut down to a minimum as excess oil drains down the outside and is apt to get on the fabrics. The scheme fitted to this servo to prevent this appeared to be satisfactory, but it is still necessary to keep the oil supply down as stated. TRANSMISSION SHAFT L OF G 100909 MS 3530 GL{G. Linnett} 605. The shaft when examined at 9000 miles did not show any appreciable wear to have taken place on the serrations as occurred on the previous shaft. PROPELLER SHAFT & UNIVERSAL JOINTS L OF G 100524 MS 3530. The vibration damper to Hs{Lord Ernest Hives - Chair} 760 which had not been balanced along with the propeller shaft was the chief cause of the heavy boom reported at 50 M.P.H. Arrangements had been made to delete this and as reported the boom was passable after so doing. This was fitted experimentally in case transmission rattles developed. There was no noticeable transmission rattles. The universal joints gave no trouble and remained free from oil leaks. There was no period from the balanced propeller shaft. MARSTON 58 M/M MATRIX RADIATOR & FITTING TO LOP E 100400 N. S. 3465 HR SCH 145-150-197. The radiator was efficient. No high temperatures of water was reached during the mileage. There should be no trouble with summer air temperatures. The chief complaint is the rattling of the radiator shutters. This could be heard from the drivers seat. We would like to draw attention to the weakness of the radiator shutters and the ease in which they are prevented from operating. The hitting of a small bird at high speed is sufficient to so bend the shutters that they either remain partially closed or open. No water leaks developed during the test. The drain pipe with its end facing forward in the air stream prevents loss of water. This has been verified on both cars. | ||
