Camshaft Timing Chain, Removing From Camshafts, Cylinder Bank 2 (Left): Installing
- The crankshaft is locked using the : T10492 or : T40069 at "TDC" point.
- The : T40331/1 is tightened on the camshaft housing to 9 Nm.
- Replace the friction disk (diamond discs) after removal.
Risk of destroying the engine with the friction disc not being installed.
- Check the installation of the friction disc (diamond disc) between the camshaft adjuster and the camshaft stub.
- The marks -1 and 2- on the camshaft adjusters must align with the corresponding locating tabs -arrows- on the camshaft housing.
-- Bring the camshaft adjuster with the camshaft timing chain positioned in the previously described installation position at the same time pay attention to the applied markings when removing.
-- Lubricate the control valves -1 and 2- on the threads and bolt head support and install all the way but do not tighten.
- Both camshaft adjusters must be able to be turned on the camshaft.
-- Remove the : T03006 .
-- Have a second technician position the : VAS6583 with the Socket : VAS261001 and : T90001 on the intake camshaft adjuster and tension to 30 Nm counter-clockwise -arrow- and hold.
-- Tighten the control valves with : T90000 as follows while the camshaft adjuster is still being held under tension:
- Control valve -2- on the exhaust camshaft 30 Nm.
- Control valve -1- on the intake camshaft 30 Nm.
Valve Timing, Checking
-- Remove the : T40331/1 .
-- Remove the : T10492 or : T40069 .
Risk of destroying the engine by adjusting the valve timing.
- Never turn the crankshaft and camshafts if the chain drive is not completely installed.
-- Using the : T40263 and : T40314 , turn the crankshaft two turns in direction of -arrow- until the vibration damper is back at "TDC".
- The marks -1 and 2- on the camshaft adjusters must align with the corresponding locating tabs -arrows- on the camshaft housing.
Procedures, where the Engine is NOT Removed:
-- Insert the : T10492 on the groove -1- in the vibration damper all the way in the hole -arrow- in the belt pulley side sealing flange. If necessary push the crankshaft slightly back and forth.
Procedure, if the Engine is Removed Due to Preliminary Work.
-- 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 position the : VAS6583 with the : VAS261001 and : T90001 on the intake camshaft adjuster and tension to 30 Nm counter-clockwise -arrow- and hold.
- It must be easy to insert the : T40331/1
.
- Do not use a hammer to install the camshaft positioning tool.
-- Insert the prepared : T40331/1 all the way into the camshaft.
- The : T40331/6 engages as shown in the flattened position -2- on the intake camshaft.
- The : T40331/7 engages as shown in the flattened position -1- on the exhaust camshaft.
If the Camshaft Positioning Tool: T40331/1 CANNOT be Inserted:
-- Remove the : T10492 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 .
Procedures, where the Engine is NOT Removed:
-- Insert the : T10492 on the groove -1- in the vibration damper all the way in the hole -arrow- in the belt pulley side sealing flange. If necessary push the crankshaft slightly back and forth.
Procedure, if the Engine is Removed Due to Preliminary Work.
-- Install the : T40069 in the hole and tighten to 20 Nm. If necessary push the crankshaft slightly back and forth.
Continuation:
-- Repeat the adjustment. Refer to Installing => Have a second technician position the : VAS6583 with the Socket : VAS261001 and : T90001 on the intake camshaft adjuster and tension to 30 Nm counter-clockwise -arrow- and hold. .
If the : T40331/1 Can be Inserted:
-- Remove the : T10492 or : T40069 .
-- Remove the : T40331/1 .
-- Position the : T90001 and : T90002 on the intake camshaft adjuster.
-- Support the Counter Holder on the exhaust camshaft control valve -2-. If necessary slightly turn the crankshaft.
-- Turn the control valve -1- a 35° additional turn using the : T90000 .
-- Position the : T90001 and : T90002 on the exhaust camshaft adjuster.
-- Support the Counter Holder on the intake camshaft control valve -1-. If necessary slightly turn the crankshaft.
-- Turn the control valve -2- a 35° additional turn using the : T90000 .
-- Install the vacuum pump. Refer to VACUUM PUMP, REMOVING AND INSTALLING .
-- Install the cylinder bank 2 upper timing chain cover. Refer to UPPER TIMING CHAIN COVERS, REMOVING AND INSTALLING .
Additional procedures. Refer to CAMSHAFT TIMING CHAIN, REMOVING FROM CAMSHAFTS .
