Illustration 1 g00572090
Rotate the engine until the timing marks “V” on the camshaft drive gear and the idler gear are aligned.
Illustration 2 g00832971
Remove two bolts (1) and plate (2) from the camshaft.
Illustration 3 g00832973
Remove camshaft (3) from the cylinder block.
Illustration 4 g00832975
If necessary, remove camshaft drive gear (4) with Tool (D) and press. Engines With a Camshaft Rear Gear
Note: All 3408E Engines have a balancer gear that is located in the flywheel housing. The balancer gear is driven by the crankshaft or the camshaft. The balancer gear has a timing mark. This timing mark must be aligned with the timing mark of the gear that drives the balancer gear. If there is access to the rear camshaft gear through the flywheel housing, the rear camshaft gear may be removed without removing the flywheel housing. If the balancer gear is driven by the crankshaft, the camshaft rear gear can be removed and installed without regarding the timing. If the balancer gear is driven by the camshaft rear gear, the timing marks on the camshaft rear gear and the balancer gear must be aligned when the camshaft rear gear is installed. Refer to Disassembly and Assembly, "Balancer Group - Remove" and Disassembly and Assembly, "Balancer Group - Install". 3412 Engines do not have a balancer gear. A dowel in the rear of the camshaft positions the rear camshaft gear on the camshaft. The rear camshaft gear is secured to the camshaft with four bolts.

(5) Flywheel housing
(6) Hole for turbocharger oil drain
(7) Camshaft rear gear
(8) Timing marks
(9) Balancer gear
The procedure that follows is for flywheel housings that have a hole for the turbocharger oil drain. Access to the camshaft rear gear may be in several possible locations. The access will depend on the flywheel housing. Covers may need to be removed. The turbocharger oil drain line may need to be removed. If there is no possible access, the flywheel housing will need to be removed. Refer to Disassembly and Assembly, "Flywheel Housing - Remove and Install". Refer to "The Flywheel Housing Has Been Removed" in this section. Note: If the balancer gear is driven by the camshaft rear gear, the timing marks on the camshaft rear gear and the balancer gear must be aligned.. If the balancer gear is driven by the crankshaft, the camshaft rear gear can be removed without regarding the timing.

(10) Studs
(11) Bolt
(12) Camshaft rear gear
Remove the turbocharger oil drain line. Use Tool (A) and remove studs (10).
Illustration 7 g00834273
The camshaft must be rotated in order to gain access to bolts (11). The last bolt will be removed when the threaded holes in the camshaft rear gear are in line with the threaded holes that mount the turbocharger oil drain line. The holes should be aligned when the engine is at top dead center. The camshaft will rotate once for every two rotations of the crankshaft. Look at the timing marks at the front of the engine on the camshaft drive gear and the idler gear. These timing marks must be aligned in order to thread Tool (C) into the camshaft rear gear. Turn the flywheel with Tool (B) and remove three of bolts (11) as the bolts become accessible.
