Install Tooling (A) on the flywheel housing. Do not tighten the bolts on Tooling (A).
Attach a suitable lifting device to the front half of the camshaft. The weight of one-half of the camshaft is approximately 74 kg (163 lb).
Install Tooling (B) 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.
Position the front half of camshaft (12) in the engine until Tooling (B) is in the first camshaft bearing.

Install thrust washers (10) and bolts (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.
Illustration 5 g00579261
Remove timing pin (16) from the storage position on the side of the engine.
Turn the camshaft until timing pin (16) can be installed through the cylinder block and into groove (17) that is in the camshaft.
Repeat Steps 1 and 15 for the camshaft on the opposite side of the engine.
