Installing and tensioning

Note

When rotating the camshaft, the crankshaft must not be positioned at TDC. Risk of damaging valves and pistons.

Precondition

l	The pistons must not be at TDC.

–	Bring the marking on the camshaft sprocket in line with the marking on the cylinder head cover (TDC for cyl. 1).

–	Fit toothed belt onto crankshaft toothed belt sprocket and coolant pump (pay attention to direction of running).

–	Fit engine support bracket on the cylinder block.

Tightening torque: 45 Nm

Note

Install support with inserted screws.

–	Install the middle and bottom timing belt guard, replace screws.

Tightening torque: 10 Nm

–	Install toothed belt/vibration damper.

Tightening torque: 40 Nm

–	Bring the marking on the vibration damper in line with the marking on the bottom part of toothed belt guard (TDC for cyl. 1).

–	Check whether the marking on the flywheel and the TDC marking are aligned -arrow-.

I -	Manual gearbox

II -	Automatic gearbox (is not mounted)

–	Install engine mount, replace screws.

–	Align unit mounting for engine → Chapter.

Tightening torques → Chapter.

–	Remove supporting device -MP9-200 (10-222A)-.

–	Install coolant expansion reservoir.

–	Install PAS reservoir.

–	Fit timing belt onto camshaft sprocket and tensioning pulley.

–	Tension timing belt → Anchor.

Further installation occurs in reverse order to removal.

Precondition

l	Crankshaft is on TDC for cylinder 1.

–	Before tensioning the toothed belt, rotate the tensioning pulley at the eccentric with the -T10020- two-hole nut turner 5 times in both directions as far as the stop.

–	Tighten the timing belt. Rotate at the eccentric with the two-hole nut turner -T10020- in -direction of arrow- as far as the stop.

–	Slacken the timing belt until the notch -1- and the pointer -2- are positioned opposite (use mirror).

–	Tighten securing nut to 25 Nm.

–	Rotate crankshaft a further two revolutions in direction of rotation of engine until the engine is again positioned on TDC for cylinder 1. When doing this, it is important that the last 45° (¹/₈ turn) are rotated forcefully without any interruption.

–	Once again inspect tension of toothed belt.

Specified value: Pointer and notch are positioned opposite.
