| X360 W/S - Cx.{Major Len W. Cox - Advertising Manager} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}11/KW.29.7.36. 34-EX. Cx.{Major Len W. Cox - Advertising Manager}1/KW.28.7.36. We have got a clutch plate which we think is better than the one we have standardised. We should like to fit this to 34-EX. We should have liked to have tried 34-EX clutch when it started to jagger before it was doped. In our experience doping clutches is like the drug habit, the more you dope them the more they want doping; therefore even though we try 34-EX before we change the clutch we shall not get a true impression of how bad it has become. When you get your new trials cars on the road, if one of them starts to jagger and you will ring us up, we can send our clutch expert down to try it immediately. The information so obtained would be of great value to us. It is a big job changing the clutch plate on 34-EX because it is an obsolete unit and has to be removed from the chassis to get at the clutch. We should want three days for the job. You will no doubt let us know when you can spare the car. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
