| -9- GEARBOX. With the exception of the 2nd gear coming out of mesh no troubles have occurred with the gearbox, ease of change. One and a half pints of oil has been the replenishment during the total mileage. The rattles from the change speed lever would not be objected to on a sports car. SERVO AND MECHANISM. The servo has been efficient and remained so throughout the mileage. There has been no need for re-adjustment. The swinging arm friction was increased to reduce front brake thumps. The linkage of the servo, causes lost movement to the foot pedal through slackness in pins. (see brakes). PROPELLER SHAFT. There has been no noticeable transmission period from the propeller shaft. There has been no oil lost from the mechanics joints. The shaft fouled the floorboards towards the finish of the mileage, approx. one foot from the front end through the floorboards settling down. REAR AXLE. The axle has been poor for noise throughout the mileage. It has deteriorated somewhat on the overrun. It has not been necessary to add any oil. Backlash in the drive has increased slightly. ROAD SPRINGING FRONT AND REAR. No fractures of the springs have taken place. Lubrication to the shackles has been maintained. The rear shackle pins show slight wear. The anchorage to the frame of the front off side spring was found quite loose at the finish of the mileage. The nuts were only finger tight. FRONT AND REAR BRAKES. The frequent necessity of adjustment of the brakes show that with higher speeds the braking area is on the minimum side, and larger drums and shoes are necessary for | ||
