(6) Assemble collet assembly (13) to the 3P1568 Indicator (14) and tighten nut (F) on collet assembly (13). Tighten collet assembly (13) on the indicator approximately one and one-fourth revolutions through the indicator's range of travel. Do not tighten collet assembly (13) on the indicator too tightly. With microgauge (15), make an adjustment to indicator (14) until the indicator reads zero, then tighten lock (G). After lock (G) is tightened, make sure indicator (14) still reads zero. (7) To check the calibration of the fuel pumps on the left side of the fuel pump housing (as seen from the governor end of the fuel pump housing), install a 6V190 Clamp (16) on sleeve shaft (17) (end away from the governor). Use a bolt as shown at location (H), to hold the clamp in position. To check the calibration of the fuel pumps on the right side of the fuel pump housing, (as seen from the governor end of the fuel pump housing), install a 6V190 Clamp (16) at each end of sleeve shaft (18) on the right side. Use a bolt at each location (J) to hold the clamps in position as shown. (8) Put indicator (14) on calibration pump (9) and hold the indicator tightly in position [in the center of calibration pump (9)]. Move the sleeve control shaft toward the governor end of the fuel pump housing to remove the end clearance. Lift the dowel pin for the crossover levers with a finger, and then let go of the dowel pin so the crossover levers will drop. Do this quickly (fast), several times. (This will remove any end play in the linkage.) Write down the dimension of the needle on the indicator. Do steps 5, 6, 7 and 8 for all of the fuel pumps. See step 9 for an explanation of how to read the dial indicator tolerances. (9) See the dimensions you wrote down in step 8. All of these dimensions must be within range (K), clockwise from -.050 to +.050 on the dial indicator. Also, there must not be more than .050 difference between the dimensions of any two pumps. If any pump is outside this tolerance, recalibration of all pumps is necessary. See examples (L) and (M) above, which show two sets of dimensions that are within tolerance.Adjustment of the Fuel Pump Calibration - V8 Engine
(1) Remove the fuel shutoff solenoid, the top cover of the fuel pump housing and the cover over the torque control group. (2) Install 3P1546 Pin (1) 15.9410 (0.6276") in hole (A). The pin length is given on the large diameter of the pin. Install the 5P6602 Adapter (2). Fasten adapter (2) in position with 1D4538 Bolt and 1D4533 Bolt. Install 8S7271 Screw (3) and use the 2P8264 Socket to tighten the screw to a torque of 2.3-2.8 N m (20-25 lb. in.) to push pin (1) against the top of the pump housing. (3) Make an adjustment to low idle screw (4) to get
