2.7 Removing toothed belt from camshaft

– To do this, turn camshafts with adapter for angle sensor - VAS 611 007/5- -E-.

– Hold camshafts via adapter for angle sensor - VAS 611 007/9and adapter for angle sensor - VAS 611 007/10- -E- in 0.0° position with a wrench.

Note

♦ The camshafts tend to turn.

♦ Use a hexagon key to hold the camshafts in 0.0° position. ♦ Always remove the hexagon key after the camshafts have been tightened.

– Tighten brakes after adjustment has been completed. – Tighten bolts -a- for brakes to 11 Nm on both sides.

– Make sure that brake indicator on display is red -C-. • It must not be yellow or green.

– Unscrew locking pin - T10340- -A-. – Tighten intake camshaft adjusted using pre-tension procedure ⇒ “3.4.1 Removing and installing camshaft adjuster for inlet camshaft”, page 211 . – Tighten camshaft adjuster on exhaust camshaft to specified initial torque ⇒ “3.4.2 Removing and installing camshaft adjuster for ex‐haust camshaft”, page 215 .

– Make sure that bolts -a- for brakes are released on both sides.

– Make sure that brake indicator on display is green -A-. – It must not be yellow or red.

– Seal camshaft adjusters -1- and -2- using suitable plugs -Afrom engine bung set - VAS 6122- . – Fit a piece of paper -A- into plugs to catch the engine oil. – The plug for the camshaft adjuster -1- on exhaust side must be pushed in slightly. – Turn crankshaft 2 turns in direction of rotation of engine.

Determining correction angle – Screw in locking pin - T10340- . – Set piston for cylinder no. 1 to TDC position ⇒ “4.7 Setting piston to TDC position”, page 155 . – Read valve timing on display and write down values. The il‐lustration shows values as an example.

Note

♦ The correction angle is determined for each individual vehicle. ♦ The value read after the engine has been cranked is used for determining the correction angle. ♦ Note the algebraic signs of the values. ♦ The correction angle results from the difference between the specification and the value which has been read after the crankshaft has been cranked twice.

♦ The correction angle is used to adjust the valve timing.

Read value ± correction angle = specification Computational example for intake camshaft: -1.2° + 2.3° = 1.1° Computational example for exhaust cam‐shaft: -1.0° + 1.8° = +0.8°

– Set determined correction angle for camshafts. Setting valve timing with correction angle – Place a cloth underneath camshaft adjuster to catch any en‐gine oil which runs out. – Remove plug taken from engine bung set - VAS 6122- from camshaft adjusters. – Remove paper from plugs and camshaft adjusters. – Clean camshaft adjusters with a cleaning cloth, and remove as much engine oil as possible. – Loosen camshaft adjuster on intake side ⇒ “3.4.1 Removing and installing camshaft adjuster for inlet camshaft”, page 211 . – Loosen camshaft adjuster on exhaust side ⇒ “3.4.2 Removing and installing camshaft adjuster for ex‐haust camshaft”, page 215 .

NOTICE

Risk of damage to engine caused by incorrect valve timing. – Do not turn crankshaft out of TDC position.

– Make sure that the piston in cylinder no. 1 is at TDC position ⇒ “4.7 Setting piston to TDC position”, page 155 . – Make sure that bolts -a- for brakes are released on both sides.

– Make sure that brake indicator on display is green -A-. – It must not be yellow or red.

– Set the two camshafts to the determined correction angle ⇒ page 194 . – To do this, turn camshafts with adapter for angle sensor - VAS 611 007/9- and adapter for angle sensor - VAS 611 007/10-E-.

If the valve timing has been set: – Tighten bolts -a- for brakes to 11 Nm on both sides.
