| - 7 - Servo & servo gears. The serve has remained in a very good condition, it has operated quite satisfactory up to the present mileage. There has no perceptible wear taken place in the serve link mechanism It has not been necessary to readjust the cams. Pedals. The bearings of these are good, no noticable wear has taken place. Starter motor. V3592 X4-384 X5620 This has not worked at all satisfactory, it has been necessary to start up the engine with starting handle on many occasions. We obtained a Bendix drive from the PARIS Depot, but found that we could not use it, owing to modifications to Bendix drives having taken place. Rear axle. The rear axle has developped a growl on picking up from low speeds, and at high speeds it is noisy. We have had no further oil leak since checking up the oil level. The O.S. bracket holding pull off spring for brake has been slightly bent over by stones hitting same. These appear to be on the weak side. Rear brakes mechanism & drums. The rear brakes have continued to squeak through the test. It has varied. On some occasions it has been bad; others hardly perceptible. The braking has remained good. We have had grit get between the dust covers and edge of drums which caused a bad screeching noise. Examination of brakes found them to be in a very good condition. Dust and grit had been washed inside of covers but had not get on to the brakes. There has been no trouble with brake mechanism and condition of drums are very good. Rear road springs & shackle bearings. Upon examination at this mileage, we found the N.S. spring had it's top leaf cracked half way accross a 3/8" rear of center bolt, and 5th leaf fem top broken right accross 2 3/8" rear of center bolt. We have fitted a new spring of the same poundage. The spring shackle pin at rear end had worn considerably. The spring clips on either springs had remained tight. We could not find any cracks on the O.S. spring. We have been continually hitting buffers during the continuation of the test. Rear shock dampers. We have dismantled the shock dampers. The lubrication of plates has been O.K. There is a slight wear taken place where serrations of plates have dug in on the hub of dampers. We have increased the friction load of these to approx. 70 Lbs. by packing up the springs with washers with a view of steadying the rear springing. The connecting links have required adjusting. | ||
