We notice that the steel magnet case of this motor is not being finished ground. The dynamo on these cars and both the dynamo and starter on the 40/50 are all ground and the subsequent finish when nickel plated is extremely good. It is also important that the inside diameter is ground on the starter to ensure good 100% magnetic contact between the pole core face and the magnet case. When assembled on the engine the finish of the starter is poor compared with the dynamo. Hs{Lord Ernest Hives - Chair}/Wst. | ||
