Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Do not turn the crankshaft or the camshaft while the camshaft gear is removed. If the front gear group is not correctly timed during installation, interference can occur between the pistons and the valves, resulting in damage to the engine.
Care must be used when removing or installing the camshaft. Do not damage the finshed surfaces of the camshaft or the camshaft bearings.
Ensure that the camshaft and camshaft bearings are thoroughly clean. Lubricate the camshaft lobes with a 50/50 mixture of Tooling (J) and clean engine oil. Apply a thin coat of clean engine oil on the camshaft bearings.

Install Tooling (B) on front housing (7). Do not tighten the bolts that hold Tooling (B) to front housing (7) at this time.
Use Tooling (H) to align Tooling (B) with the camshaft bearings. Tighten the bolts that hold Tooling (B) to front housing (7). Remove Tooling (H). Note: Tooling (H) should move freely from the bore of Tooling (B).

Install Tooling (C) on the rear of the camshaft.
Use two people to install the camshaft. Use Tooling (D) to assist in aligning camshaft (8) with the camshaft bearings. Carefully slide the camshaft into the cylinder head from the front of the engine. Keep the camshaft level while the camshaft is being installed in the cylinder head. The weight of camshaft (8) is approximately 39 kg (86 lb). Note: Rotate the camshaft during installation. This will prevent the camshaft from binding in the camshaft bearings.
Remove Tooling (C) and finish installing camshaft (8) in the bore. Note: Tooling (C) must be removed before the camshaft can be completely installed in the cylinder head.
Remove Tooling (A) from the cylinder head.
Remove Tooling (B) from the front housing.
