Eric Platford - Chief Quality Engineer} PN.{Mr Northey} OY. Expl. No. X.4604 (crossed out) X.634 REF. Hs{Lord Ernest Hives - Chair}12/LG1.10.23. OBJECT OF TEST. To reduce torque reaction vibration on the 40/50 HP. chassis. TESTER. G.{Mr Griffiths - Chief Accountant / Mr Gnapp} W. Hancock. CONDITIONS. Tested on 4-EX and 49-GB on the road. SUMMARY OF TEST. We have not so far had friction dampers between engine and frame on the 40/50 HP. chassis. The best arrangement so far tested is to lock up the present compensating arrangement at the front of the engine. With the rear end of the engine supported on a compensating mounting, we get worse results. It might be improved with dampers. Hs.{Lord Ernest Hives - Chair} | ||
