ARMATURES AND COMMUTATORS. Will you please put in hand two armatures, one for each of the above machines, having 41 slots to:- D.71713 - Armature L.O.P. D.71713 - Armature Assembly. D.71708 - Oil Thrower. - 1 off. .D.71709 - Wire for Armature. - 2 lbs. D.71712 - Armature Coil. - 41 off. D.71711 - Commutator L.O.P. D.71711 - Commutator Assembly. If the 45 slot armatures have not been built all the parts can be used, except new wire is required for the coils and a new oil thrower. The commutators are made, we understand, but they could be undone and new copper fitted (D.71628/9). The instructions replace those sent to you, reference:- S.S. Chassis - BY {R.W. Bailey - Chief Engineer} /RD7/ML.30.4.28. Data Machine - BY {R.W. Bailey - Chief Engineer} /RD3/ML.12.7.28. This change in armature will involve an alteration to the bearing bracket, see alterations 2585/6/D. One set of blueprints herewith. BY {R.W. Bailey - Chief Engineer} /RD. | ||
