A clearance cut on the edge of the metering cup, located between the dovetail and the longhorizontal slot, has been provided for the pump disc tool and should be facing you (Fig. 25).8. With the fork of the tool in line with the meter-ing cup clearance cut and centered aboutthe hook shaft end, press felts to the left withtool until the pump disc is in contact with endof the hook shaft.9. Press hook oil control shaft bushing (L) to theleft until control shaft (D) is approximately 1/16 inch away from pump disc (F). Make surethe control shaft pivot pin (E) seats in thedepression at the center of the pump disc.Tighten set screw (C, Fig. 25) and withdrawassembly tool. Be sure sir seal felt (J) hasseated against the pump disc.10. Turn the hook oil control shaft (D, Fig. 26) untilscrew hole (M) is accessible. Manually rotatepump disc (F) so its stop pin (N) is 90° above screw hole.11. Rotate metering cup so the short slot (T) is 180° from stop pin (N). Now, install hook oil control finger(B) by first hanging the hooked portion of finger over the stop pin and lowering to insert the projectionat bottom left into the short slot of the metering cup. Tighten the finger in place by means of screwand washer, making sure the hook oil control fingerdoes not bind or distort metering cup.12.

With the oil control adjusting shaft set atmaximum, the feed roller point of contact with themetering cup felt should be at the mid-point of theslot that permits the metering cup felt to enter themetering cup.NOTE: The feed roller should be in contact with the metering cup felt through its complete travel.UPPER MAIN SHAFTIn a high speed machine, the alignment of the take-up mechanism is extremely important and is controlledby the left and right position of the upper main shaft. Should the main shaft position be altered, it isimperative that the take-up alignment be checked before operating.
