| X.4222. Extract from Hs{Lord Ernest Hives - Chair}4/LG2. 9.21. SPRING DRIVE. X.4222. We find that it is impossible to remove the spring drive from the crankshaft when the engine is in position in the frame. It would appear that if the nut was modified on the end of the crankshaft, it could be got off. Hs.{Lord Ernest Hives - Chair} | ||
