-7- were in a fine condition. The braking surfaces were a smooth glossy surface with no signs of ridges. It was not affected by a stone being dragged along this surface. The inner cooling fins had a piece 2.5" long broken off, evidentally, fouling against same. It has in no way affected the drum. The O.S. brake drum was found saturated with oil, due to the bad leak from the axle at this side. The oil had been drawn in from the guard. It had not overflowed from the inside. The brake shoes were in an excellent condition. The auxiliary shoes showed no deterioration. The spring controlled shoe with the stronger springs G.80080 fitted are a decided improvement. There was no indication of the brake linings having been dragged along the shoe. FRONT AXLE & BRAKES to L.C.P.G.78632. N.S.3176. G.79603 Brake Drums - "R.R." Castings similar to Lake & Elliott's specification. D.71260 Bolts - Replacing studs for fixing Mud Plates. The Front drums taken off and examined at a mileage of 6,500 were in the opposite condition to those of the rear. The N.S. had a deep groove in the centre, and the metal had embedded itself in the shoes. The O.S. was in a worse condition. There were a series of deep grooves, and more metal was embedded in the shoes. The braking had been efficient and quiet. The auxiliary shoes were operating satisfactorily. REAR AXLE to LCP.G.78624 - 12 K 41 RATIO. Oil retaining baffle fitted to O.S. Axle Tube to G.L.397. G.78808 Oil Retainer. G.78810 Oil Retaining Tube. The rear axle is a good standard for quietness, and has remained so during the mileage. The fitting of the oil baffle has unfortunately had the opposite effect, the loss of oil from the O.S. has been abnormal during each day's run. It has averaged out 1 pint for every 500 miles. We are puzzled at this result as previously it has been effective. We intend to have it dismantled at the Paris Depot, as we have not the required tackle or tools here for this kind of work. SHACKLING & SPRINGS. Spring Controlled Rear Shackle on Front R.H. Spring to NS.{Norman Scott}3452. F.84418 Bracket, & - F.84425 Springs. | ||
