Bailey - Chief Engineer} ) FROM DA.{Bernard Day - Chassis Design} (crossed out) HS.{Lord Ernest Hives - Chair} ) RECEIVED 4 IX 31 (stamp) AJL ORIGINAL See me DA{Bernard Day - Chassis Design}1/M1.9.31. HS{Lord Ernest Hives - Chair} (crossed out) x7941. x3806. 25-EX. - 10,000 MILES TEST. In the report dated 5. 8. 31. it is mentioned that there was a failure of the lubrication to the rear shock damper ball joints due to the Bijur pipe being struck with stones and loosening the joint. There has been a similar arrangement to this in connection with lubricating the brake multiplying levers on the axle. It is true that it is slightly protected by the shock damper ball end bracket. Has there been any trouble experienced with this joint, and do you think if we reproduced it on the ball end it would be satisfactory? This we can easily do. With reference to the servo sticking up due to dust clogging the driving pins, Mr. Hardy suggests that we should cut a flat on each side at right angles to the driving surfaces so as to allow the dust to escape. Would you please try this. DA.{Bernard Day - Chassis Design} | ||
