| -8- dampers, when checked for load had retained their poundage. We have not had any sign of knocks or wear in the hydraulic dampers. REAR AXLE TO L.O.P. G.78285. Axle No. EXP.8 - 90 M.{Mr Moon / Mr Moore} 11 x 41. INCORPORATING N.S.2989 60" Wheel Track. N.S.3063 One Shot Lubrication. N.S.3042/3 Increased Spring Bracket Centres.- The rear axle has remained very good for quietness and absence of periods. A rather bad oil leak has developed along the o/s tube, which has leaked into the housing of the brake drum, draining away by way of the drain pipe. The n/s is quite free from any oil leaks. We fitted a breather cap to the axle to see whether it would overcome this oil leak, but no improvement has taken place since the fitting of it. REAR BRAKES TO L.O.P. G.78278. Hand and Foot Brake Straps lined with "Mintex W" Brake Shoes.- The rear brakes have been efficient, but have caused very bad groans. No undue wear has taken place on the shoes, and the Mintex lining gives the same appearance as reported re the front brakes. The drums do not show any hard score marks, and have remained in a fairly good condition. REAR ROAD SPRINGS TO L.O.P. F.79627. Drawing No. F.81737. Lubrication No. F.81757. Type 1200 lbs. Initial Camber 8.250.- We have taken down the n/s rear road spring and examined it for lubrication. With the exception of the rear top leaf for approx. 4" which was found to be dry and in a rusty condition, the remaining portion of the spring leaves had been amply lubricated. The anchorage pins and bearings were in good condition. The spring clips, both on n/s and o/s, have remained firmly tightened up. There was no sign of fracture on any of the spring leaves which were examined. UNIVERSAL JOINTS & PROPELLER SHAFT TO L.O.P. G.76851.- The propeller shaft has very lightly fouled the cross member at some time during the maximum bump. We noticed during the early part of the mileage a slight vibration from the propeller shaft, which is caused by the universals being slightly on the tight side. This quickly disappeared, and we have not had any sign of it during the remainder of the run. The universal joints are now perfectly free and are entirely oil retaining. Only a few drops has been added to the front universal joint. We have the same symptoms as reported on 23-EX: a fair amount of oil flung out of the front sliding joint. CARBURETTER TO L.O.P. E.80530. INCORPORATING Lec.2786 Mod. to Air Silencer. Scheme 1220 Modified Petrol Inlet. E.80742 Carb. Body replaces E.78727.- We have had considerable trouble with the tendency to seize up of the float chamber cover. The slightest bit of dirt | ||
