538 MOTION PICTURE HANDBOOK
wheel, D-38, P. 1, may be removed as follows: First loosen screws 216 (two of them), P. 4, and then, by means of knurled knob at its top, unscrew framing carriage guide rod 72 P, P. 4, and pull it out. Next remove the screw which holds the upper end of the link which joins the framing carriage and framing lever casting 11 P, P. 4. Next loosen the two screws, one at each lower corner of the nickel plated shield in the side of the mechanism back of the fly wheel, and raise knob 296, P. 1. You may then, by working it around a little, pull the whole framing carriage out to the right — on the crank side of the mechanism.
No. 27. To Remove Fly Wheel Shaft 61 P, P. 3, follow Instructions Nos. 1, 16, 18 and 26, then loosen a set screw in the face of the framing casting just behind the lower gate hinge. You will be obliged to remove the gate in order to get at this set screw. (See Instruction No. 5.) This set screw holds the bronze bearing in which the shaft runs, and you may then, using either a copper or a hard wood punch, drive the shaft bearing and inner end of the toggle out into the interior of the frame casting.
No. 28. Striper Plate D-32, P. 1, (F-F, P. 5), may be removed by taking out the three screws at its lower end. See P. 5.)
No. 29. Fly Wheel, D-38, P. 1, may be removed by taking out the two set screws in its hub. They are deeply countersunk, and must be backed out for quite a distance before the wheel will be released. When the wheel is released from the screws, hold the fly wheel on the opposite end stationary while you pull the wheel off with a twisting motion.
No. 30. To Open the Oil Well follow Instruction No. 29, and then loosen the screw at each lower corner of the nickel plated shield behind the fly wheel and remove it; next remove four machine screws in the black casting on the end of the framing carriage. These screws hold the cover of well E, P. 5, and having removed them you can pull the cover off, tapping it lightly to break the joint. Before starting this job, you can, if you wish, remove the whole framing carriage from the machine. See Instruction No. 26. It is well to remove the oil well cover, say once in each five or six hundred hours running, and clean it out thoroughly.
Never use graphite in the oil well unless you want trouble, and plenty of it.
Caution: In replacing the oil well cover be sure that you wipe both the surfaces perfectly clean. If you do not there is apt to be a leakage of oil.
