Install Tooling (D) on the flywheel housing. Do not tighten the bolts on Tooling (D).
Install Tooling (C) on the end of the front half of the camshaft.
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.
Attach a suitable lifting device to the camshaft. The weight of one-half of the camshaft for 3512B Engines is approximately 36 kg (80 lb). The weight of one-half of the camshaft for 3516B Engines is approximately 41 kg (90 lb).
Position the front half of camshaft (12) in the engine until Tooling (C) is in the first camshaft bearing.
Rotate camshaft (12) and tighten the bolts for Tooling (D).
Rotate camshaft (12) and insert the camshaft until the camshaft is slightly protruding from Tooling (D).

If the dowel was removed from the front half of camshaft (12), install the dowel. Install the dowel to 22 0.5 mm (0.9 0.02 inch) from the surface of the camshaft.
Attach a suitable lifting device to rear half of camshaft (13). The weight of one-half of the camshaft for 3512B Engines is approximately 36 kg (80 lb). The weight of one-half of the camshaft for 3516B Engines is approximately 41 kg (90 lb). Install spacer (15) and the rear half of camshaft (13) onto the front half of camshaft (12). Install bolts (14) and tighten to a torque of 55 7 N m (41 5 lb ft).
Install Tooling (C) and Tooling (E) on the rear half of camshaft (13).
Rotate the rear half of camshaft (13) and insert the camshaft into the engine.
Remove all Tooling. Repeat Steps 1.a through 1.k for the camshaft on the opposite side of the engine. Go to Step 3.
The following steps are for the installation of the camshaft in 3508B Engines. The camshaft is one piece.
Install Tooling (D) on the flywheel housing. Do not tighten the bolts on Tooling (D).
Install Tooling (C) on the end of the camshaft.
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.Note: Ensure that the camshafts are installed according to the marks on the ends of the camshafts.
Attach a suitable lifting device to the camshaft. The weight of the camshaft is approximately 46 kg (101 lb). Insert the camshaft in the engine until Tooling (C) is in the first camshaft bearing.
Install Tooling (E). Rotate the camshaft and tighten the bolts on Tooling (D).
Rotate the camshaft and insert the camshaft into the engine.

Install thrust washers (10). Install bolts and washers (9) that fasten the camshaft to the engine.
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.
