| ( 8 ) REAR AXLE. 37) Bracket has been designed to overcome this trouble. 39) The bell crank levers stuck through dirt having entered the roller bearing cage. DUNLOP WHEELS. 43) Design taken up with Dunlops. A new type of spoking to be tried out. SERVO & MECHANISM. The Servo was efficient. The linkage pins fouled the Servo and jammed when reversing, there was not sufficient clearance for full working conditions of the Servo. A detailed sketch and report was sent to W previously. When dismantled, the Servo friction plates were in a 100% condition. The departure from using a bolt for the T anchorage of the linkage was not a success, considerable wear took place in the pin hole of the eyelet which caused chattering. STEERING. The Steering was selective and stable. The period of slight reactions between 40/60 M.P.H. did not increase in intensity and could not be considered objectionable. The lubrication of the pivot pins had been ample. When dismantled, the needle bearings in the bottom yoke had not been revolving and had caused indents in the outer bush. The soft steel bushes at the bottom of the pivot pins, had become excessively scored. These should have been made of hardened steel. The needle bearings in the top yoke, showed signs of being on the tight side. CROSS STEERING & SIDE STEERING JOINTS. These were in a good condition and had been well lubricated. The chattering effect noticeable early on in the mileage had disappeared. CLUTCH. The Clutch with V M 20 linings fitted, was smooth in engagement under normal driving conditions. It was inclined to grab at the final engagement. It was very slow stopping when hot. When dismantled, the cast iron pressure plate was found to have distorted dish shape to the extent of .015". The disengaging finger levers had become tight in the needle bearings. There are no means of lubricating these bearings, & with the entier absence of oil fumes, | ||
