Tightening specifications. Refer to OVERVIEW - LEFT CAMSHAFT TIMING CHAIN .
Secure crankshaft -1- in "TDC" position using Locking Pin For Crankshaft :T40237 .

NOTE:

Replace the bolts that were tightened with an additional turn.

Replace the locking bolt seal for the "TDC" marking.

CAUTION:

Risk of damaging valves and piston crowns.

If camshafts are rotated, crankshaft may not rest with any piston at "TDC".

-- Check whether camshafts of both cylinder heads stand in "TDC" position.

It must be possible to secure the camshafts with the Camshaft Adjustment Pins:T40060 .
The pin -arrow- in the Camshaft Adjustment Pins:T40060 must be perpendicular to the center line of the camshaft on cylinder bank 1 (right).

The pin -arrow- in the Camshaft Adjustment Pins:T40060 must be perpendicular to the center line of the camshaft on cylinder bank 2 (left).

CAUTION:

Risk of damaging valves and piston crowns.

If camshafts are rotated, crankshaft may not rest with any piston at "TDC".

NOTE:

If the camshafts are not secured, it is possible to correct them slightly with the Camshaft Correction Tool:T40061 by installing the camshaft chain sprocket on the camshaft.

-- Install the left camshaft timing chain with the camshaft chain sprocket, the guide rail and the tensioning rail.

The slots in the camshaft chain sprocket must be at the middle position in relation to the threaded holes in the camshaft.

-- Tighten the bolts -1 and 3- for the guide rail and the tensioning rail.

-- Install both camshaft chain sprocket bolts -2- loosely.

It must still be possible to rotate the camshaft chain sprocket on the camshaft and it must not tip.

-- Secure the left camshaft 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.

-- Pull the drill -4- out of the alignment hole, thereby releasing the chain tensioner.

-- Install the right camshaft timing chain with the chain sprocket and chain tensioner.

The slots in the camshaft chain sprocket must be at the middle position in relation to the threaded holes in the camshaft.

-- Tighten the chain tensioner bolts -1-.

-- Install both camshaft chain sprocket bolts -2- loosely.

It must still be possible to rotate the camshaft chain sprocket on the camshaft and it must not tip.

-- Secure the right camshaft 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.

-- Pull the drill -3- out of the alignment hole, thereby releasing the right chain tensioner.

-- Pre-tighten the right camshaft chain sprocket using the Chain Sprocket Tensioner:T40062 and torque wrench to 20 Nm in direction of -arrow- and hold the pretension.

-- Tighten the bolts -1 and 2-.

-- Remove Chain Sprocket Tensioner:T40062 and Camshaft Adjustment Pin Camshaft Adjustment Pins:T40060 .

-- Tighten the remaining bolts for the right camshaft chain sprocket.

-- Pre-tighten the left camshaft chain sprocket using the Chain Sprocket Tensioner:T40062 and torque wrench to 15 Nm in direction of the -arrow- and hold the pretension.

-- Tighten the bolts -1 and 2-.

-- Remove Chain Sprocket Tensioner:T40062 and Camshaft Adjustment Pin Camshaft Adjustment Pins:T40060 .

-- Tighten the remaining bolts for the left camshaft chain sprocket.

-- Remove the Crankshaft Holder:3242 .

CAUTION:

Components could be damaged by the camshaft timing chain jump off.

Turn crankshaft only in direction of engine rotation -arrow-.

-- Turn the crankshaft two turn until the crankshaft is just in front of "TDC".

-- Lock the crankshaft -1- from turning using the Crankshaft Key:3242 to 20 Nm.

CAUTION:

An inaccurate "TDC" setting will cause an inaccurate setting.

If the crankshaft was only rotated slightly past "TDC", first rotate it back approximately 10° and then rotate it in engine rotation direction again to "TDC".

-- Check whether camshafts of both cylinder heads stand in "TDC" position.

It must be possible to secure the camshafts with the Camshaft Adjustment Pins:T40060 .
The pin -arrow- in the Camshaft Adjustment Pins:T40060 must be perpendicular to the center line of the camshaft on cylinder bank 1 (right).

The pin -arrow- in the Camshaft Adjustment Pins:T40060 must be perpendicular to the center line of the camshaft on cylinder bank 2 (left).

-- If one of the camshafts does not lock, loosen all the bolts -arrows- for that particular camshaft chain sprocket about 1 turn.

-- Mount the Camshaft Correction Tool:T40061 over the bolt heads.

-- Turn the camshaft by the Camshaft Correction Tool:T40061 just a little back and forth until it is possible to insert the Camshaft Adjustment Pins:T40060 .

The bolt -arrow- in the Camshaft Adjustment Pins:T40060 must be perpendicular to the center axis of the camshaft.

-- Tighten the bolts for the camshaft chain sprocket with the Camshaft Correction Tool:T40061 and the Camshaft Adjustment Pins:T40060 still attached to approximately 5 Nm.

-- Remove the Camshaft Adjustment Pins:T40060 and the Camshaft Correction Tool:T40061 .

-- Tighten the camshaft chain sprocket bolts to final torque.

-- Repeat the procedure on the other cylinder bank if necessary.

-- Remove the Crankshaft Holder:3242 .

-- Check the valve timing once again. Refer to Installing .

Install in reverse order of removal. Note the following:

-- Install the sealing plug -arrow- for the "TDC" marking in the upper part of the oil pan. Refer to OVERVIEW - OIL PAN UPPER SECTION .
