| -5- SERVO & MECHANISM TO LOP. G53403 & SCHEME 2526. This has operated satisfactorily. The Bijur lubrication to the shafts was ample, and bearing in good condition. We note that the servo linkage from the foot pedal lever to the servo has bolts fitted instead of the standard pins. We question whether this is correct to drawing, also a considerable amount of play was in these links causing lost motion of the foot brake pedal when the car was delivered here. PEDAL TO LOP. F86004 D TYPE. The shafts for the pedals had not been securely fastened by the biting-in bolt on the bracket fastened to the frame. This caused the shaft to oscillate and was the cause of the failure of the Bijur lubrication, bringing the feed hole out of line. The result was the brake pedal bearing picked up on the shaft and finally became almost solid. This caused the failure of the lubricating pipe. The oiling scheme of this shaft should be altered. There is one oil feed hole to each pedal bearing, the holes are too far up on the side of the shaft to be half full of oil before any can run out. We should recommend that two holes for each bearing be drilled at the bottom of the shaft, making sure that a small amount of oil will feed the bearings. PROPELLOR SHAFT & UNIVERSAL JOINTS TO LOP. G53436 & SCHEME 2589. The capacity of the Mechanic Joints is one syringe ful. At 2000 miles a quarter of a syringe of oil was necessary in either joint. At 7500 miles one eighth of a syringe was needed in either joint. There is no leak from the outer shell. A small leak comes out of the inner side of the joint when the car is standing. The joints do not show any wear and appear to be quite satisfactory. FRONT AXLE, BRAKE DRUMS, BRAKES & MECHANISM. The front axle has remained O.K. The brakes have been very good, and show little signs of wear. They required one notch of adjustment at 7500 miles. The pivot pins and bearings had been well lubricated. The oiling system of the front axle would appear to be satisfactory. Brake toggle shafts were well lubricated. No wear could be detected in the pivot pins. The front axle unit has been supplied with oil every 500 miles. FRONT SPRINGS AND SHACKLES TO LOP. F85538. These were taken down and examined. We noticed that the spring leaves had not been cadmium-plated. The condition of the springs was quite good, there was no sign of digging in at the ends of the leaves. Lubrication has been plentiful. The shackle pins were well lubricated with the exception of the n/s front spring pin, this had not been well lubricated, chiefly due to the feeding hole not corresponding to the hole in the pin. The brass bush showed signs of picking up and was rough. The Bijur supplying this part was quite O.K. The spring clip had not stretched, and springs have been firmly held throughout the test. REAR AXLE, REAR BRAKES, BRAKE DRUMS, ETC. TO L.O.P. G53593. The rear axle casing is O.K. The gear noise has been fair and has remained so throughout the run. There is no sign of wear in the pinion housing. The brakes and brake drums were in a perfect condition when examined. There was ample lubrication of the brake countershafts and brake toggles. The brake drum shields have been effective in keeping out water, dirt, etc. The brakes were adjusted at 7500 miles two turns on the adjustment. The rear axle unit has been supplied with oil every 500 miles. | ||
