| L.A.H.L. To H.{Arthur M. Hanbury - Head Complaints} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to Wor.{Arthur Wormald - General Works Manager} c. to Hy.{Tom Haldenby - Plant Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}6/KW.18.12.34. You will note that in Hancock's recent daily report he states that the starting handle cannot be inserted owing to the rubber engine mounting having taken a permanent set. We have gone into the matter on cars at present being produced, and also on our own experimental cars, and find that with the old type starting handle this cannot occur. With the two-piece starting handle, however, for the dropped front cross member, there is difficulty in inserting the shaft when the engine has fallen appreciably owing to the washer at the back of the spring catching on the radiator bottom tank. There does not seem to be any reason why the diameter of the washer should not be reduced. If this is done we think that the rubber mounting will be able to subside to the limit before the insertion of the starting handle is obstructed. With regard to the movement of the engine when idling and under torque, we anticipated that there might be some criticism with regard to this point, and have therefore arranged for provision to be made on all chassis turned out with the rubber engine mounting for torque reaction dampers to be fitted. Therefore if the customer complains about the engine movement this can be eliminated by the torque reaction damper. Until we get the customers' reaction it is difficult to know whether these should be fitted before the cars leave the Works or not.
