| -2- No quantitative measurements were taken of flutter as the movement was now small and it was considered more important to proceed with an endurance run. --- The following failures have occured - (1) Rubber bearings - Silentbloc and Inlox - due to end thrust. FB.3143, FB.3144 - 14.20 hrs. and 17.50 hrs. (2) Hard rubber collars in rear engine mounting FB.3498 - 10 hrs. (3) Rubber Buffers (rebound only) FB.2975 - 10 mins. (approx.) (4) O.S. Torque arms. Aluminium FB.2980 - 22 hrs. Pressed Steel FB.2924 - 10 hrs. (5) Dampers (O.S.Front) Bellows failed. (6) Frame - Gusset and side members collapsed. FB.3195, 3196 - 32 hrs. (7) Central Bracket for lower levers. FB.3275. Contact made by lower levers. (8) Spherical rubber for torque arm. FB.3086 - 17.50 hrs. (9) Pure rubber spring seatings 5 hours. The following attention is being paid to the points of failure - (1) Rubber Bushes. Inlox, Silentbloc stepped and unstepped bushes have been tried. We have also tested an experimental bush which is being developed in America for Packards. In order to ascertain the cause of the end movement, which is experienced by moving the front end of the chassis from bump | ||
