• Secure crankshaft in "TDC" position using Crankshaft Holder 3242.

-- Mount the Camshaft Fitting Tool - T40096 onto the teeth of the intake camshaft so that one arm of the clamping tool engages in one sprocket half.

• The wider arm must engage into the wider half of the sprocket.

-- Tension the tensioning tool with the thumb wheel until the tooth faces align.

The camshaft thrust bearings and the bearing cap for cylinder bank 1 are marked after work is performed on the exhaust side to prevent them from being installed incorrectly:

• Both alignment sleeves -arrows- must be inserted into the openings on the thrust bearing.
• The alignment sleeves must engage in the openings in the cylinder head.

-- Check the installation direction of the thrust bearings:

• The round edge -arrow 2- points towards the intake side.
• The cornered edge -arrow 1- points towards the exhaust side.

-- Place the camshafts in the "TDC" position in the thrust bearings.

• The intake camshaft -1- must be able to be stopped with the Camshaft Adjustment Pins T40060.
• The bolt -arrow- in the Camshaft Adjustment Pins T40060 must be perpendicular to the center axis of the camshaft.
• The exhaust camshaft -2- must be positioned so that the groove -arrow A- runs parallel above the joint -arrow B- between the thrust bearing and the bearing cap.

-- Apply the appropriate bearing cap to the corresponding thrust bearing.

-- Loop a cable tie -arrows- on the right and left around the thrust bearing and the bearing cap and tighten them.

• The intake camshaft -1- must be able to be stopped with the Camshaft Adjustment PinsT40060.
• The bolt -arrow- in the Camshaft Adjustment PinsT40060 must be perpendicular to the center axis of the camshaft.
• The exhaust camshaft -2- must be positioned so that the groove -arrow A- runs parallel above the joint -arrow B- between the thrust bearing and the bearing cap.

Install in reverse order of removal. Note the following:

-- Remove the Camshaft Fitting Tool - T40096.

-- Install the camshaft timing chains, refer to Installing .
