| To. Rm.{William Robotham - Chief Engineer} F T H 4006 CHATEAUROUX. 2/10.3.39. Do we get this on 9 B V S.B.V.- BENTLEY III. Thank you for your telegram : " Please examine wheels where bolts secure same to " shaft for cracks stop should expect cracks to " follow a radius based on the bolt hole stop wire " result and state of engine bearing stop Robotham. to which we replied, " Wheels free from cracks bearings excellent " axleshafts despatched. Waller. The bearings were particularly good for the mileage, 23,665. There was circular patch about .400" dia. cracked up in one intermediate, but they were otherwise faultless. The ones examined were Nos, 2,3,4,5, and 7 main bearing caps and Nos. 5 and 6 big-ends. We cannot detect any cracks in the road wheels, round the bolt holes, or elsewhere. If you have found any cracked at Derby, they may be the ones on which tests with loose nuts were carried out. They were painted blue (9.B.V.) There was ample evidence of water having entered the O.S.R. brake during yesterday's running. The foul between the main oil pipe and the nearside cross-steering tube must also be occurring on 9.B.V. and should be put right. We do not know if it has been seen to for the final design. The axle shafts left Paris by Air Mail yesterday morning (Thursday). Replying to Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}2/MH.{M. Huckerby}6.3.39, we will try and give you some further information on the effect of oil level in the front dampers, when we get away again. In the meanwhile we are going right through the brake system to analyse the friction which holds on the rear brakes. We will also fit the undersheets. We think that the increased out-put servo, i.e. the one using a cam action, and 180° useful travel, should be pushed ahead for 3.B.50 and I4.B.V. In the meanwhile, we should like to try the 30° cams which are being tested at Derby. | ||
