(1) Front Removal
(2) Rear Removal
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 rear 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 finished 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 (D) and clean engine oil. Apply a thin coat of clean engine oil on the camshaft bearings.

Install Tooling (A) and Tooling (B) on the rear of camshaft (18). Install Tooling (A) on the front of camshaft (18).
Install Tooling (C) on the front housing or the rear housing. Tooling (C) is used to support the camshaft.
Use two technicians to install the camshaft. Use Tooling (C) to assist in aligning the camshaft with the camshaft bearings. Carefully slide the camshaft into the cylinder head. Keep the camshaft level while the camshaft is being installed in the cylinder head. The weight of the camshaft is approximately 35 kg (77 lb).Note: Rotate the camshaft during installation. This will prevent the camshaft from binding in the camshaft bearings.
Remove Tooling (A) and Tooling (B) from the camshaft.
