6. Inspect and replace all damaged parts or gaskets. See the topic, SPECIFICATIONS, for checking wear of fuel rack bearing, camshaft journals and bearings.
7. If the camshaft bearings are being replaced, align the hole in the bearings with the oil passage in the housing and press the bearings into the bore of the housing. The bearing (12) is pressed in until the flange on the bearing is against the machined surface on the end of the pump housing.
8. Align the hole in the bearing (14) with the oil passage in the housing and press the bearing into the bore of the housing until it is 6 7/64" from the machined surface (16).
9. Align the hole in the bearing (15) with the oil passage in the housing and press the bearing into the bore of the housing until 7/16" of the bearing remains beyond flush of the machined surface (16) as shown.
10. If the rack bearings are replaced, the bearing (17) should be pressed into the housing until it is flush with the machined surface (16).
11. If the oil manifold (13) has been removed, make certain that the cross drilled holes in the injection pump camshaft housing line up with the drilled holes in the manifold. This will also make certain that the spray holes in the manifold are properly positioned under the lifter rollers.
12. Assemble the remaining parts in the reverse order of disassembly.
13. Tighten the nut (5) on the end of the camshaft to the specified torque value. See the topic, SPECIFICATIONS.
14. After lightening the nut (5) on the end of the camshaft, the width of the slot on the end of the camshaft should be .376" - .381".

IS-Machined face. 17-Fuel rack bearing.
15. After installing the fuel pump assembly on the engine and timing the pump camshaft, adjust the lifter settings. See the topic, FUEL PUMP LIFTER SETTING (ON ENGINE).
FUEL PUMP LIFTER SETTING (ON ENGINE)
If the injection pump lifters have been removed or disturbed from their original settings, it is necessary to reset them. The lifter settings should also be checked periodically and reset if necessary, to compensate for wear in the timing gears and pump lifters. If the lifter is too high, injection will begin early; if too low, injection will begin late. See the topic, FUEL INJECTION PUMP LIFTER YOKE AND PUMP PLUNGER INSPECTION.
NOTE
The maximum quantity of fuel that can be injected by each pump into the cylinder, and accordingly, the maximum horsepower output of the engine at a given operating speed is determined by the fuel rack setting. This rack setting should be changed only in accordance with information furnished Caterpillar dealers. See the topic, GOVERNOR ADJUSTMENTS.
LOCATING TOP CENTER FLYWHEEL MARK
The lifter settings can be set in the following manner:
I. Turn the crankshaft in the direction of the engine rotation to "Top Center" (TC) on the compression stroke of the cylinder for which lifter is to be set.
2. If the "Top Center" mark on the flywheel is turned past the pointer, turn the flywheel backward approximately 60 0 Then turn the crankshaft again in the direction of crankshaft rotation until the "Top Center" mark aligns with the pointer.

PREPARING TO DISASSEMBLE IMPULSE DRIVE COUPLING
I-Locknut. 2-Drive cup. 3-Rotor shaft.
3. Mark the direction of the drive spring spiral in drive cup (2) and remove the spring.
NOTE
The spiral of the spring will wind in the wrong direction if the spring is installed incorrectly.
4. Mark pin (4) to allow the trip arm to be installed on the correct pin.
n015
PREPARING TO REMOVE TRIP ARM 4-Pin. 5-Trip arm spring. 6-Trip arm. 7-Drive flange.
NOTE
If only drive cup (2) and trip arm (6) are to be removed, it is not necessary to remove the rotor from the magneto housing. Block or hold drive cup (2) to prevent it from turning and loosen locknut (1). Proceed with Steps 1 through 4.
5. Press drive flange (7) from the rotor shaft.
NOTE
When an arbor press is used to remove drive flange (7), the oil slinger is usually damaged and a new one must be installed.
Assembly
1. Make certain all parts are clean. Apply ball and roller bearing lubricant between the turns of the impulse spring.
2. Press drive flange (1) on the rotor shaft.
NOTE
Make certain an undamaged oil slinger is in place, before the drive flange is installed.
3. Install trip arm (2) and the trip arm spring.
IMPULSE DRIVE COUPLING ASSEMBLY I-Drive flange. 2-Trip arm. 3-Spacer. 4-Plate. 5-Washer.
6-Drive cup spacers. 7-Drive cup. a-Locknut.
4. Install spacer (3), plate (4), washer (5) and drive cup spacers (6).
5. Install drive cup (7) by first pulling the inner eye of the drive spring one turn out of the drive cup. Next place the cup on the rotor shaft and latch the inner eye of the spring in the notches in the drive cup spacers (6). Push the drive cup a short distance on the shaft and turn the cup one full turn (to wind up the drive spring). Push the drive cup (7) in place to engage the drive flange (1).
6. Install locknut (8) and stake it in two places to lock the nut on the shaft.
BEARING REMOVAL
A replaceable bearing is located in a bearing assembly on the rotor shaft between the magneto drive and the rotor magnet. The rotor must be removed from the magneto housing and the drive (either an impulse drive coupling or a driving lug) removed before the bearing assembly can be removed from the rotor shaft. See covering topics.
NOTE
The seal must be installed with the lip facing the magneto drive.
