MANAGERS AND PROJECTIONISTS 1^1 The entire governor, including the ball bearings, may be removed as a unit by following Instructions Nos. 1 and 2. Then remove taper pin 70P, P. 2, and pull off arm 117P, P. 2. Next remove screw 141P, P. 2, and a similar screw immediately under the arrow head of 853P, P. 2; this releases bar HOP, P. 2. Next loosen screws 853P, P. 2, whereupon the entire governor including the ball races and beveled gear may be pulled out toward the front. INSTRUCTION NO. 7.— To remove ball bearing 138P, P. 3, and spring 134P, P. 2, follow Instructions Nos 1, 2 and 6, which release the governor as a unit. Now remove screw 822P, P. 2, and its mate on the opposite side and tap lightly on the end of shaft 130P, P. 3. The ball bearing is just a tight fit, and by tapping lightly on the end of the shaft with a copper or brass punch it will slip off the shaft, and thus releases the governor, weight, spring and sleeve. INSTRUCTION NO. 8.— To remove spring 134P, P. 2, follow Instruction No. 7. INSTRUCTION NO. 9.— To remove weight 145 P, P. 2, follow Instruction No.7, and then drive out the pins holding the governon-carrying arms. These pins are not tapered and may be driven either way. INSTRUCTION NO. 10.— To remove ball race on inner end of governor shaft, follow Instruction No. 7, and then drive out taper pin in hub of gear 136P, P. 2. The large end of each taper pin used in this machine may be recognized by a file mark on the hub behind the head of the pin. Gear and ball race may now be driven off. INSTRUCTION NO. 11.— To remove flywheel, 26P, P. 2, take out screw in end of shaft and carefully pry off the cap under it, whereupon the wheel may be pulled away. This also releases pinion 27P, P. 2 and 3. INSTRUCTION NO. 12.— To remove bearing bracket 30P, P. 3, which is also the oil well cover, follow Instruction No. 11. Then pull off pinion 27P, P. 3, remove screws 867P (six of them), P. 2, whereupon the bracket including the cam 34P, P. 2, gear 33P, P. 2, and its shaft 25P, P. 2, can be pulled away as a unit. In removing this bracket pull the parts away carefully, moving them straight outward, then up and to the right, being careful not to strain any part, else you may injure the cam pin or the star or both. INSTRUCTION NO. 13.— To remove cam 34P, P. 2, follow Instructions No. 11 and 12, and drive out taper pin engaging
