Dimensions of conical shaft for MCB Maximum diameter: 13 m {Mr Moon / Mr Moore} /m — Minimum 11,2 m {Mr Moon / Mr Moore} /m — Length of cone: 9 m {Mr Moon / Mr Moore} /m. Dimensions of conical shaft, for other types Maximum diameter: 15 m {Mr Moon / Mr Moore} /m — Minimum 12 m {Mr Moon / Mr Moore} /m — Length of cone 15 m {Mr Moon / Mr Moore} /m. Magnetos type MCA 1, 2 MCAs are ordinarily provided with an expanded base on both sides for the easier fitting on the motor — On request said type may be supplied with the simple narrow base, and in this case the total width is reduced of 19 m {Mr Moon / Mr Moore} /m. | ||
