ENGINE SIDE TRAYS AND UNDERSHEETS LOP.EB.1073.LEC.3461.3560.

The engine is inclined to become splashed with mud during wet weather. The chief reason is the space left, at the junction of the front under pan and the side trays, the space left under the radiator, the holes cutout for the rear spring anchorage and the oil pump, on the other side there is too much space round the front expansion box. We would suggest that having an efficient radiator the necessity for louvered side trays have lost their usefulness.

FRONT AXLE AND BRAKES LOP.GB.870. N.S.3701 GB.573. -

4° Transverse inclination of Pivot, incorporating N.S. 3717 Mod. to exclude water from brakes.

The chief item this axle gives, is stability with steering. There has been no sign of any wobbles developing. During the first part of the test the steering was heavier for shunting etc. than with the other axle, but with the freeing of the axle pins and drop in load of the cross sterring tube the heaviness has apparently decreased. The lubrication of the pivots has been ample and no wear is noticeable.

The brakes have been efficient and no undue wear has taken place. No adjustment has been necessary during the mileage and we purposely did not adjust them until the mileage was completed. We then found the total amount of wear was 6 turns of the cam adjustement. The cam adjustement must be protected as it rusts up, and cannot be operated without force. The brake and drums when examined were in a excellent condition. There was no scoring of the brake drums. The new scheme of water excluder has no advantage over the present scheme? We have reported the uselessness of the brakes after the car has been washed. To have to ask a customer to dry his brakes out each time the car is washed is not as it should be. A quantity of sludge has entered, covering the anchorage plate and the brake cam mechanism. The brakes are free from water entering while running in wet weather. The Rudge Whitworth hubs and wheels show no sign of having become loose or chattering. The wheels have been free from any loose spokes.
