| -5- REAR AXLE LOP. G.53661. BEVEL PINION HAVING GREATER TOOTH AREA TU G.53716/7. LARGER TIMKEN CENTRE CASING G.53707/8 & OIL PIPES TO G.53718/9 TO SUIT NEW PINION. RESERVOIRS G.77663/4 FITTED TO SHAFTS TO BS.{A J. Barnes - Assistant Manager} 1863. AXLE BRAKES LOP. J.53594.- The axle has been very good for oil retaining, no oil has been added. We are of the opinion that a portion of the over-run period comes from the rear axle, also on the overrun at approx. 10 M.P.H. there is a slight period from the rear axle. Neither of these we should consider objectionable. The axle generally is very quiet. The rear brake shoes and brake drums have remained in a very good condition. Only two turns of the adjustment nut has been necessary. The n/s toggle shaft was not receiving sufficient oil when examined at 5,000 miles and became very sluggish. The bijut pipe lines were flushed out with oil and no sluggishness of the toggle shaft has occured since. At 9,000 miles it was O.K. There was insufficient clearance under the body for the reservoirs and axle casing. The o/s reservoir hit a well let into the rear of the body and the axle casing hit the floor boards of the rear seat. More clearance was given for these. No objectionable squeaks developed from the brakes. REAR SPRINGS AND FITTINGS LOP. G.56083. ROD. TO 230 ABBOT. FIRTH SILICO MANGANESE STEEL CADMIUM PLATED.- Outside examination of the rear springs found them to be in very good condition and they appear to be well lubricated. The spring clips on arrival here were tightened up one full turn of the nut. At 5,000 & 9,000 miles no further tightening was needed. Spring shackles and pins are well lubricated. No wear can be detected. Buffer clearance before starting test was: n/s 3.625" o/s 3.937". At 5,000 miles it remained the same. At 9,000 miles it remained the same, no set having taken place in the springs. PROPELLOR SHAFT & UNIVERSAL JOINTS LOP. G.53436.- The propellor shaft and universal joints have remained in very good condition. No loss of oil has taken place from the joints throughout the test. At 5,000 miles the universal joints were parted and examined. The condition of bearings was a 100% job. At 9,000 miles they remained in the same condition. No wear can be detected in the sliding joint on the propellor shaft. There has been a slight oil leak from same due to excess of oil. REAR SHOCK DAMPERS LOP. F.55965.- The poundage of the rear shock dampers was not correct when checked upon arrival here. We corrected the poundage, making them 80 x 80. The poundage has remained consistent throughout the test. A slight knock developed in the o/s damper laterally. Considerable loss of oil has taken place from the dampers through the glands, replenishments being necessary every 2,000 miles. There was insufficient lubrication to the connecting links. The bijure S.O. were taken out and S.I. fitted altering the drops per stroke of the pump from 7 to 17. Lubrication at the finish of the test was fair but could be improved. FRONT SHOCK DAMPERS LOP. F.55944.- The loads checked before test were 60 LP.{Mr Lappin} 80 RP. at 9,000 miles the poundage was E/S 50 LP{Mr Lappin}/80 RP. O/S 40 LP.{Mr Lappin}/75 RP. Oil leaks have not been so prominent from glands as the rear dampers. No knocks have been discernable. Increased lubrication to the connecting links had to be made the same as the rear. | ||
