Install Camshaft Drive Gear
6V6080 Torque Multiplier5P1748 Socket 1. Put plate (3) in position on camshaft drive gear (2) and install bolts (4).2. Put 2P2506 Thread Lubricant on the threads of bolt (6).3. Fasten a hoist to camshaft drive gear (2). Put the camshaft drive gear in position on the camshaft, aligning the holes in the gear with the top and bottom bolt holes for the cam thrust plate. Install washer (5) and bolt (6). Tighten bolt (6) by hand.Slide Camshaft Rearward
Be careful when moving the camshaft to avoid damaging the cam lobes.
Slide the camshaft rearward, back into position.Install Thrust Plate
1. Install the thrust plate using the access holes in the cam gear to install the bolts.2. Rotate the crank, turning the camshaft gear until all three thrust plate bolts can be installed and tightened.3. Rotate the camshaft until the camshaft timing pin can be installed.4. Install camshaft timing pin. A pry bar may be inserted between the camshaft section bolts to adjust the camshaft position as needed. 5. Remove the crankshaft timing pin from the timing location.6. Turn the flywheel opposite the direction of normal rotation a maximum of 20°.7. With bolt (6) hand tight, turn the flywheel in the direction of normal engine rotation until the crankshaft timing pin can be reinstalled in the crankshaft.* This procedure holds the backlash in the timing gears in the direction of normal engine rotation.
If the crankshaft timing pin location is missed, do not turn the flywheel in the opposite direction to install the crankshaft timing pin. If the crankshaft timing position is missed, repeat Steps 6 and 7.
8. Remove the camshaft timing pin.9. Use the torque multiplier and the socket to tighten bolt (6) to a torque of 2000 275 N m (1480 200 lb ft).10. Carefully hit bolt (6) with a hammer, and repeat Step 9. Repeat this procedure until the bolt torque does not change.11. Remove the crankshaft timing pin.12. Verify the correct camshaft timing. See the topic, Camshaft Timing Check in Testing and Adjusting for 3606 and 3608 Diesel Engines, form SENR3599.Install Governor Drive
8S2328 Dial Indicator Test Group 1. Move the camshaft to the rear against plate assembly (9).2. Put shims (4) in position on pinion assembly (2), and install new O-ring seals (5). Put clean engine oil on the O-ring seals. Refer to the Parts Manual for part numbers of replacement seals.3. Put pinion assembly (2) in position in rear housing (1), and install the four bolts that hold it in place.
Be sure the camshaft is all the way to the rear against the plate assembly and the pinion is forced upward against the plate assembly when checking the backlash between the two gears. If the camshaft is forward when the backlash is set, there will not be enough clearance between the gears when the camshaft moves to the rear.
4. Use the 8S2328 Dial Indicator to check the backlash between the pinion gear and the governor drive gear. Add or remove shims (4) as
