• Secure crankshaft in "TDC" position using :3242  .

-- Mount the :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 :T40060  .
• The bolt -arrow- in the :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.

-- Screw in two camshaft chain sprocket bolts with five turns each into the threaded openings of the camshaft as shown in the illustration.

-- Attach the :T10172  with the :T10172/5  to both of the bolts and turn the camshafts approximately 30° counterclockwise -arrow- until the groove -arrow A- in the camshaft points vertically towards the cylinder head sealing surfaces -arrows B-.

Install in reverse order of removal. Note the following: 

-- Remove the :T40096  .

-- Install the camshaft timing chains. Refer to CAMSHAFT TIMING CHAIN, REMOVING FROM CAMSHAFTS .
