When starting to torque 124-5932 Lever Assemblies, the difference between the face of the 141-6730 Plunger and the 2N-2658 Bolt is about 0.03 mm (.001 in). By setting the 141-6737 Adjustable Microgauge (2) on top of the 141-6727 Calibration Pump Assembly (8), the 141-6737 Plunger can be positioned 25.40 mm (.001 in) above the face of the 3P-1542 Barrel (7).
Illustration 24. (9) 2N-2658 Bolt. (10) 124-5940 Shutoff Lever.3. As the 2N-2658 Bolt (9) is torqued, the 141-6730 Plunger will move down flush with the 3P-1542 Barrel (7) or will be very close to being flush. The calibration can begin from this point. The 2N-2658 Bolts must freely turn in and out of the 124-5940 Shutoff Levers (10) because the calibration depends on where the head of the 2N-2658 Bolt (9) first begins to clamp the 124-5940 Shutoff Lever for the starting point of the calibration.End Play Adjustment
1. In order to save time, use two torque wrenches (color-coding is convenient for distinguishing between the two wrenches). Set one torque wrench to 1.7 N m (15 lb in) and the second torque wrench to N m (35 lb in).

The SMFS 109-0324 Governor And Fuel Injection Pump Group had the dowel in the middle of the sleeve and a large amount of end play in the shaft was acceptable. Now that the 126-7232 Dowels (3) are between two 124-5934 Sleeves, the amount of end play is important. It is necessary that an adjustment be performed to minimize the amount of end play in the 124-5941 Shaft (1).3. The 126-7232 Dowels (3) are located between two 124-5934 Sleeves. Set the 126-7232 Dowels between 0.25 to 0.40 mm (.010 to .016 in) by tapping in the 4N-1826 Dowels (2) until the desired end play is achieved.* With the 1.7 N m (15 lb in) torque wrench, torque the 2N-2658 Bolts to 1.7 N m (15 lb in).* Then use the 4 N m (35 lb in) torque wrench to torque the 2N-2658 Bolts to 3.4 N m (30 lb in) in order to calibrate within specifications.Calibrating the 124-5932 Lever Assemblies.

Move to the other side and turn the second 2N-2658 Bolt (1) until just begins to clamp (feels snug).* Alternate between sides and tighten each 2N-2658 Bolt about 15 degrees each time.
