Hs{Lord Ernest Hives - Chair}12/LG1.10.23 OBJECT OF TEST. To reduce torque reaction vibration on 40/50 HP. chassis. TESTER. G.W.Hancock. CONDITIONS. Tested on 4.EX and 49-CB 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 got worse results. It might be improved with dampers. Hs.{Lord Ernest Hives - Chair} | ||
