Note: This is an optional procedure to install the camshaft. The preceding tool list shows the required tooling for installing the camshaft from the front of the engine or the rear of the engine.
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.
To install the camshaft from the rear of the engine, go to Step 3 through Step 6. To install the camshaft from the front of the engine, go to Step 7 through Step 10.

Install the camshaft from the rear of the engine.
To install the camshaft from the rear of the engine, install Tooling (F) on the front of camshaft (8) with Tooling (G). Note: Carefully align Tooling (F) with the end of camshaft (8). If the adapter and the camshaft are not aligned, the camshaft may not be removed. The adapter and camshaft bearing will interfere.
Install Tooling (E) on Tooling (F).
Use two people to install the camshaft. Carefully slide the camshaft into the cylinder head from the rear 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 (E), Tooling (F), and Tooling (G) from the camshaft.
