| X242 To Rm. {William Robotham - Chief Engineer} Hs {Lord Ernest Hives - Chair} /Les.12/KW.17.8.36. SHOCK DAMPER KNOCKS PROGRAMME. (1) 6-B-IV is fitted with tight bearings requiring 10 lbs. ball pin load to rotate the shaft. (2) 2 car sets of hardened shafts are being produced per By {R.W. Bailey - Chief Engineer} /HEB. {H. Biraben} 43/M.29.7.36. (3) By. {R.W. Bailey - Chief Engineer} is investigating design in order to increase inner bearing diameter. (4) Brock estimates that diamond boring for the bushes will be in production in 5 weeks. (5) A new lever and bushes have been sent to Paris in order that the faulty lever in the O.S. rear damper on 22-G-V can be returned for examination. (6) Six chassis under instructions from By {R.W. Bailey - Chief Engineer} /HEB. {H. Biraben} 1/M.18.5.36 have been fitted with .00025" bearing clearances. It is thought, however, that the majority of bearings in dampers have even less clearance. (7) Delco's use a hardened steel shaft in bronze bushes. (8) Accurate production could be made easier by (a) pressing the lever on the shaft. (b) by using a straight end bush with a disc soldered in after the shaft. Hs {Lord Ernest Hives - Chair} /Les. | ||
