25. Illustration 4 g00832975 4. 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.
26. Illustration 5 g00832150 (5) Flywheel housing (6) Hole for turbocharger oil drain (7) Camshaft rear gear (8) Timing marks (9) Balancer gear 1. 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.
27. Illustration 6 g00832648 (10) Studs (11) Bolt (12) Camshaft rear gear 2. Remove the turbocharger oil drain line. Use Tool (A) and remove studs (10). Illustration 7 g00834273 3. 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.
28. Illustration 8 g00834303 4. After the other three bolts have been removed and Tool (C) has been threaded into the camshaft rear gear, remove the bolt that is accessible when the engine is at top dead center. When the other three bolts have been removed, thread Tool (C) into the camshaft rear gear. Remove the fourth bolt (11). Note: Tool (C) must be used to hold the camshaft rear gear while the camshaft is removed. Tool (C) will keep the balancer gear engaged with the camshaft rear gear. Illustration 9 g00834315 5. Tighten Tool (C) evenly in order to remove the camshaft rear gear from the camshaft.
29. Illustration 10 g00572090 6. Check that the timing marks (V) on the camshaft drive gear and the idler gear are aligned. Illustration 11 g00833004 7. Remove two bolts (13) and plate (14) from the camshaft. Illustration 12 g00833007 8. Remove camshaft (15) from the cylinder block.
30. Illustration 13 g00833008 9. If necessary, remove camshaft gear (16) with Tool (D) and press. Illustration 14 g00834376 10. If necessary, use Tool (E) in order to remove dowel (20) from the camshaft. The Flywheel Housing Has Been Removed
31. Illustration 15 g00832518 1. Loosen four bolts (17). loosen the bolts approximately 6.4 mm (0.25 inch). Use Tool (F) and loosen the camshaft rear gear (18) from the camshaft. 2. Remove Tool (F). Remove four bolts (17) and the camshaft rear gear (18). 3. Refer to "Engines With a Camshaft Rear Gear". Use Step 6 through Step 10. Copyright 1993 - 2021 Caterpillar Inc. All Rights Reserved.

34. Illustration 1 g00834103 1. Install the key (1) in the camshaft (2). Be sure that the key (1) is seated in the camshaft (2). Illustration 2 g00834106 (2) Camshaft (3) Dowel (X) 8.5 ± 0.5 mm (0.33 ± 0.02 inch) 2. Install dowel (3) in the rear of camshaft (2). Install dowel (3) to a dimension of 8.5 ± 0.5 mm (0.33 ± 0.02 inch).
35. Illustration 3 g00834109 3. Install camshaft drive gear (4) on camshaft (2) if camshaft drive gear (4) has been removed. There are two methods that can be used in order to install camshaft drive gear (4) on the camshaft. Preferred Method - Mechanically press camshaft drive gear (4) on camshaft (2) without heating camshaft drive gear (4). Alternative Method - Heat camshaft drive gear (4) to a maximum temperature of 205 °C (400 °F) for no more than one hour and manually install camshaft drive gear (4) on camshaft (2). Do not use a torch to heat camshaft drive gear (4). 4. Put 8T-2998 Lubricant on the camshaft lobes and the rollers of the lifters. Put clean engine oil on the bearing journals of the camshaft. Illustration 4 g00834110 5. Carefully install camshaft (2) in the cylinder block. Do not force the camshaft into position. If resistance to camshaft installation occurs, turn the camshaft so the lobes will align the bearing journals with the camshaft bearing bores.
36. Illustration 5 g00834113 6. Align the "V" marks on the camshaft drive gear and the idler gear in the front of the engine. Illustration 6 g00834115 7. Install plate (5) on the cylinder block. 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.
