Coverley - Production Engineer}/RH.{R. Hollingworth}1/ETM.2.4.36, and the print of Ex.1.24, concerning the assembly of the side and cross steering tube ends, with particular reference to the Bentley, B.56-BN.{W.O. Bentley / Mr Barrington} We will deal with the items as numbered:- No.1. The locating washer for positioning the ball relative to the lever has to be used in all cases where we have a metal water and mud excluding device, because this has to be threaded over the stem of the ball pin. We understand that this is the device for mud exclusion which is preferred to the leather gaiter. It would appear therefore, that the suggested scheme on Ex.1.24 becomes impossible with all modernised water excluding schemes on this type of steering tube joint. We understand, however, that it is proposed to adopt the SpectreCodename for Phantom III type of steering tube joint on all our cars at a convenient date, as this joint is lighter and cheaper. The ball locking scheme as criticised would appear to work more satisfactorily if the dimensions of the detail were adjusted and also the limits, and we suggest that you may wish to take this matter up with BY.{R.W. Bailey - Chief Engineer} No.2. With reference to the contact pieces or ball pads and the possibility of their being assembled 180° out of the correct position, we notice your suggestion to go to the type examplified by GB.1056, having a beard or locking portion in the slot of the tube. There appears to be no mechanical objection to this, but it would appear that the cost of machining is increased materially. On the rear end of the Bentley side steering tube ball pads FB 605/6 are used and these are turned pieces so arranged as to require no location, and we suggest | ||
