Camshaft Timing Chain, Removing From Camshafts, Cylinder Bank 1 (Right): Installing

• The crankshaft is locked using the :T40264/3  or :T40069  at "TDC" point.
• The :T40331/1  is tightened on the camshaft housing to 9 Nm.
• Replace the friction disk (diamond discs) -item-  13 and -item-  15 after removal.

-- Oil the control valves -1 and 2- on the threads and the control valve contacts surface and install loosely.

• Both camshaft adjusters must be able to be turned on the camshaft.

-- Remove the :T03006  .

• The help of a second technician is necessary for the following step.

-- Have a second technician tension the :VAS6583  with the Socket :VAS261001  and :T90001  on the camshaft adjuster for the exhaust camshaft to 30 Nm counter-clockwise -arrow- and hold.

-- Tighten the control valve with Socket :T90000  as follows while the camshaft adjuster is still being held under tension:

• Control valve -2- on intake camshaft 30 Nm.
• Control valve -1- on exhaust camshaft 30 Nm.

Valve Timing, Checking

-- Remove the Camshaft Positioning Tool:T40331/1  .

-- Remove the Camshaft Lock:T40264/3  or Crankshaft Locking Pin:T40069  .

-- Using the :T40263  and :T40314  , turn the crankshaft two turns in direction of -arrow- until the vibration damper is back at "TDC".

-- Install the :T40069  in the hole and tighten to 20 Nm. If necessary push the crankshaft slightly back and forth.

Continuation:

• The help of a second technician is necessary for the following step.

-- Have a second technician tension the :VAS6583  with the :VAS261001  and :T90001  on the camshaft adjuster for the exhaust camshaft with 30 Nm counter-clockwise in direction of -arrow- and hold.

• Do not use a hammer to install the camshaft positioning tool.

-- Insert the prepared :T40331/1  all the way in the camshaft.

• The :T40331/4  engages as shown in the flattened position -1- on the intake camshaft.
• The :T40331/5  engages as shown in the upper asymmetrical groove -2- on the exhaust camshaft.

If the :T40331/1  CANNOT be Inserted:

-- Remove the :T40264/3  or :T40069  .

-- Insert the prepared :T40331/1  all the way in the camshafts as previously described. For this turn the crankshaft slightly.

-- Loosen the control valves -1 and 2- a half a turn using the :T90000  .

• The notch -1- on the vibration damper aligns to the locating tab -2- on the belt pulley side sealing flange.
