Cylinder Bank 2 (Left):
-- Attach both of the camshaft adjusters without camshaft timing chains to the cylinder head and then loosely screw on the bolts -1 and 2-.
-- Position the :T40269 onto the camshaft adjuster for the left intake camshaft and counterhold with a wrench -2-.
-- Tighten the bolt -1- by hand.
-- Turn the intake camshaft with the wrench counterclockwise until the thread for the camshaft clamp is in the lower center of the camshaft housing opening.
-- Tighten the left bolt -arrow left- on the :T40264/2 .
-- Position the :T40269 onto the camshaft adjuster for the left exhaust camshaft and counterhold with a wrench -2-.
-- Tighten the bolt -1- by hand.
-- Turn the exhaust camshaft with the wrench counterclockwise until the thread for the camshaft clamp is in the lower center of the camshaft housing opening.
-- Tighten the right bolt -right arrow- on the :T40264/2 .
-- Remove the bolts -1 and 2- by counterholding with the wrench and the :T40269 . Remove the camshaft adjuster.
Continuation for Both Cylinder Banks:
-- Position the :T40272 onto the :T40263 .
-- Attach the adapter to the bolts on the vibration damper.
- The semi-round countersink -arrow A- on the :T40272 must face the semi-round countersink -arrow B- on the vibration damper.
Ignore the notch on the :T40272 .
-- Turn the crankshaft to "TDC" in direction of engine rotation -arrow-.
-- If necessary, turn the crankshaft slightly back and forth to insert the :T40264/3 by hand into the vibration damper opening and all the way into the cylinder block.
Further installation is performed in reverse order of removal, while noting the following:
-- Install the vacuum pipe adjusting element for the turbocharger. Refer to OVERVIEW - TURBOCHARGER .
-- Install right coolant pipe. Refer to OVERVIEW - COOLANT PIPES .
-- Position the camshaft timing chain on the camshafts. Refer to CAMSHAFT TIMING CHAIN, REMOVING FROM CAMSHAFTS .
-- Install the high pressure pipe. Refer to HIGH PRESSURE PIPE, REMOVING AND INSTALLING .
-- Install the high pressure pump. Refer to HIGH PRESSURE PUMP, REMOVING AND INSTALLING .
-- Install the ignition coils. Refer to IGNITION COILS WITH POWER OUTPUT STAGES, REMOVING AND INSTALLING .
Risk of damaging valves and piston heads after working on valve train.
- The motor must not be started for about 30 minutes after installing camshafts because the hydraulic equalization elements must seat themselves.
- To ensure valves do not strike pistons when starting, carefully rotate engine at least two full revolutions.
