1. Attach a suitable lifting device to rear half of the camshaft. The weight of one-half of the camshaft for 3516E Engine is approximately 47 kg (104 lb). . Install spacer (12) and the rear half of the camshaft onto the front half of the camshaft. Install bolts (13) and tighten to a torque of 55 ± 7 N·m (41 ± 5 lb ft).

   Note: Ensure that the camshafts are assembled according to the marks on the ends of the camshafts. If the dowel was removed from the front half of the camshaft, install the dowel. Install the dowel to 12.0 ± 0.5 mm (0.47 ± 0.02 inch) from the surface of the camshaft.

2. Install Tooling (C) on the front housing. Do not tighten the bolts on Tooling (C).

   Note: Tooling (C) can be installed on the flywheel housing in order to install the camshaft from the rear of the engine.

3. Install Tooling (B) on the ends of the camshaft. Install Tooling (D) on Tooling (B) which is installed on the front of the camshaft.

4. Ensure that the camshaft and the camshaft bearings are clean. Place clean engine oil on the lobes and the journals of the camshaft. Also place clean engine oil on the camshaft bearings.

5. Rotate the camshaft and insert the camshaft into the engine. Position the camshaft in the engine until Tooling (B) is in the front camshaft bearing. Rotate the camshaft in order to align Tooling (C) and the camshaft bores. Tighten the bolts for Tooling (C).

6. Rotate the camshaft and insert the camshaft into the engine. Remove Tooling (D) from Tooling (B). Remove Tooling (B) from the camshaft. Remove Tooling (C) from the front housing.

7. Install thrust washer (10) and bolts (11).

8. Install the bolts removed from the front housing for installing Tooling (C).

   NOTICE
   If the camshaft is out of time more than 18 degrees (approximately 1/2 of the timing pin is out of the groove), the valves can make contact with the pistons. This will cause damage to the engine. Refer to Testing and Adjusting, "Camshaft Timing" for more information.

9. Remove timing plate (15) from the storage position under the rear camshaft cover.

10. Turn the camshaft until the timing pin can be installed through the cylinder block and into the groove that is in the camshaft. Refer to Testing and Adjusting, "Camshaft Timing" for more information.

11. Remove bolts (17), cover (16), and plug (18) from flywheel housing (19).

12. Install one bolt (17) into the flywheel housing through the hole for plug (18). Use Tooling (E) and a ratchet to turn the flywheel until bolt (17) can be installed through the hole and into the flywheel. Doing so will position the No. 1 cylinder at the top center. Refer to Testing and Adjusting, "Finding the Top Center Position for the No. 1 Piston" for more information.

13. Use the following procedure in order to install camshaft drive gear (8).

    1. Clean the taper of the camshaft and the tapered bore of the camshaft gear with a lint free cloth saturated with solvent to remove oil. Clean the parts again with a lint free alcohol wipe in order to remove any residue. The the alcohol wipe will dirty after cleaning the parts. Clean the parts again with a lint free alcohol wipe until no residue is left on the alcohol wipe.

       Note: The camshaft and the tapered bore of the camshaft gear must be clean, dry, and free of residue before assembly.

    2. Ensure that the camshaft timing pins and the timing pin for the flywheel are installed.

    3. Place camshaft drive gear (8) in position. Remove the backlash by rotating the gears in the opposite direction of camshaft rotation.

       Note: For "Standard Rotation" engines, turn the camshaft drive gears COUNTERCLOCKWISE. For "Reverse Rotation" engines, turn the camshaft drive gears CLOCKWISE.

    4. Install bolt (6) and ring (7). Ensure that the hole in the ring is properly seated on the locating pin.

    5. Tighten the bolt to a torque of 360 N·m (265 lb ft).

    6. Place a Mark on the bolt.

    7. Place a driver against the retaining plate of the camshaft gear. Strike the driver solidly with a hammer 3 to 4 times.

    8. Tighten the bolt again to a torque of 360 N·m (265 lb ft).

    9. Repeat Steps 13.g and 13.h until the Mark has turned at least 90 degrees.

14. Remove the timing pin from the camshaft. Install the timing pin in the storage position under the rear camshaft cover.

15. Install the O-ring seal on engine speed/timing sensor (5).

16. Apply Tooling (F) to the threads of engine speed/timing sensor (5). Install the engine speed/timing sensor in the flywheel housing and tighten to a torque of 40 ± 5 N·m (30 ± 4 lb ft).

17. Install cover (4) on the flywheel housing.
