| - 5 - HPS.{Horace Percy Smith - Experimental Factory Mgr}/RH.{R. Hollingworth}1/VS.{J. Vickers}21.5.37. Servo Motor LOP.GB.1908. H.S.1631-1689. H.S.3971-4403. Lightened Servo. Friction linings in V.M.30 were in good condition, and each had worn .006". The operating levers Ex.25697/8 (40°) were slightly indented on the cams, and the thrust races were rather deeply indented. Both end thrust races, too, were more deeply marked than is usual. There was no lack of grease on any of the above parts. (The operating levers have completed only 12,950 miles). All other parts were in good condition, including the dashpot and friction-damper. Chassis 6.B.IV. All parts have done 16,000 miles unless otherwise stated. Rear Axle LOP.GB.619. 10 x 41 ratio. This axle had been damaged by the recent accident, the O.S. axle shaft, GB.1379, being badly bent at the inner end, 4" from the bevel-gear. The centre-line of the shaft was .086" out of truth measured at the bevel-gear. The N.S. shaft was undamaged. Bevel Pinion Ex.15037. This was in good condition, also the nose bearing GB.1386. Thrust Bearing S.5595. - Ransome and Marles Double Purpose M.D.J.T.30 - in good condition, but when measured had .001" "float". The Bevel Wheel GB.186 was in good condition, but the thrust bearing had .0015" "float". The "nip" washer for the pinion bearing was worn .0005", but the latter had not been moving and there was still .001" "nip" left. continued. | ||
