Remove the camshaft gear.Note: This is an optional procedure to remove the camshaft. The preceding tool list shows the required tooling for removing 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.

Removal of the camshaft from the rear of the engine
To remove the camshaft from the rear of the engine, install Tooling (B) on the front of camshaft (8) with Tooling (C).Note: Carefully align Tooling (B) 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 (A) on Tooling (B).
Carefully slide the camshaft to the rear of the engine for removal. Use two technicians to remove the camshaft. Keep the camshaft level while the camshaft is being removed from the cylinder head. The weight of the camshaft is approximately 39 kg (86 lb).Note: Rotate the camshaft during removal. Rotating the camshaft will prevent the camshaft from binding in the camshaft bearings.
Remove Tooling (A), Tooling (B), and Tooling (C) from the camshaft.
