MOTION PICTURE PROJECTION 557 carry with it gear, G-148-B, P.4, and the fly wheel shaft will easily drop out of opposite end of bearing. TO REMOVE COMPLETE GOVERNOR UNIT OF VERTICAL SHAFT AND GEARS Due to the fact that the governor, vertical shaft, and gears operating same are practically one unit, and the removing of any one of these parts requires the following-out of practically one general operation, it is best for the sake of brevity, and to avoid confusion and repetition, to describe the removal process in general. To remove any one of the vertical shaft or governor parts, it is quite necessary to strip the mechanism down to a state where sufficient working space is available. First scratch mark all gears to insure the same mesh when replacing, then remove screws holding top plate P-207-D, P.6, then loosen set-screw S-146-A, P.2, and lift off focusing knob K-119-A, P.2, and remove left door link screw S-181-D, P.6. Now lift top plate off and remove complete intermittent movement. This last operation will expose the governor unit as pictured in plate 4. Then carefully drive out taper pin (or remove screw if machine is old model) from gear G-102-G, P.4 and G-120-G, P.4. Next remove center screws out of governor upper link holder H-121-G, P.3 (or drive out taper pin if mechanism is old model). Then grasp bevel gear No. 3-G-138-G, P.4 and pull upward. In this way, vertical shaft will pull out, thus releasing other connecting parts.
