| To / From HS.{Lord Ernest Hives - Chair} C.K. ORIGINAL. 2 Hal/LG24.2.20. X.3461 NEW TYPE REAR SHOCK ABSORBERS. We find a certain difficulty in fitting shock absorbers to existing cars even when they are despatched with the necessary fittings. We are sending cars away with the spring bracket made to take the arm and ball end for the shock absorber but we are not fitting the arm. This arm is fixed on by means of taper bolts. The large end of the taper is facing towards the rear axle casing. This makes it very difficult to make a satisfactory job of reamering the taper hole for the bolt. There is no room to turn the reamer because of the large diameter of the rear axle tube. Our tests have proved that it is very necessary that these taper bolts should be an excellent job. We recommend that the taper bolts should be put in from the other side. This will make it a much more practical job to do away from the works. We suggest also a coachbuilders drawing and templates be got out at once to show what clearances are necessary for these new shock absorbers. We believe that in a great number of case it will be found necessary to alter the fixing of the rear mudguard stays. We find that the lubricator on the end of the shock absorber lever fouls the brake bracket on the axle. This occurs on the bump rig and we have had one case on the road. The lever has been set out from the original arrangement because it fouled the frame. Contd. B M 332 V (100) | ||
