| -2- No.1/WJ.18.7.33. Cont'd.{John DeLooze - Company Secretary} that this type of propeller shaft will only need lubrication every 10,000 miles. Also we ought to get considerable reduction in cost. We have bought a propeller shaft to fit to the Bentley and the actual price of the complete propeller shaft is less than we pay for our material. (5) Steering. We wish to run this car with a Marles Weller steering. Although the steering on the Bentley is reasonably good we should like to gain experience of a 10,000 miles test on the Marles Weller. (6) Engine Gears. The engine will be fitted with a modification to the engine gears to overcome gear rattle. (7) Brakes. We propose trying larger diameter brake drums on the front. This helps us with our compensation and has other advantages. (8) Front Axle. We have a front axle which we wish to test which has less transverse lean on the pivots. We hope to fit this on to all Bentley cars after the first 200. (9) Controllable Shock Dampers. The dampers on the Bentley are the same as those fitted to our other cars and the control on that car would be a very definite improvement and one we cannot neglect. (10) Gearbox. We wish to try a Peregrine size gearbox on this car. We expect to take one of the Peregrine boxes which we have in stock and fit on to it. The advantage we shall gain from this is a saving of approximately 50 pounds weight, and should be reduced cost. We are certain we have a very big margin on our gearboxes and considering we only used the most expensive material we ought to gain by having less weight. (11) Steel Brake Hoses. We wish to try a set of these. The advantage we shall gain is less expansion, which will allow for some wear before it is necessary to adjust. | ||
