–	Unscrew earth wire -1-.

Unscrew securing bolts -arrows- and remove assembly mounting on engine side.

–	Unscrew securing bolts -1- and swivel alternator in -direction of arrow-.

–	Lift motor up sufficiently by turning spindle in order to allow for unscrewing securing bolt of engine mounting.

–	Unscrew securing bolts -2- of engine mounting and 3 bolts -1- of lower toothed belt guard.

–	Lift out engine mounting upwards.

Caution

When loosening and tightening the securing bolts, the camshaft sprockets must in any case be secured with the counterhold -T10172-.

The camshaft clamp -T10477- may not be subjected to load when tightening the camshaftsprockets in order to avoid damage to the tool or to the camshafts.

–	Secure camshaft adjuster with counterhold -T10172- and unscrew plug -1-.

Note

When adjusting the valve timing, both camshaft sprockets must be loose.

–	Secure camshaft adjuster and camshaft sprocket with counterhold -T10172-.

–	Loosen securing bolts -1- and -2-.

–	Loosen securing bolt -3- of belt tensioner and release tension of belt tensioner by turning the eccentric -4- (hexagon socket insert) in -direction of arrow-.

–	Push toothed belt from camshaft sprockets.

–	Renew securing bolts -1- and -2- and tighten them hand-tight.

–	Rotate camshafts via securing bolts -1- and -2- into positions described below.

–	Grooves -1- of inlet camshaft -3- are positioned right above horizontal camshaft centre line -2-.

–	Grooves -1- of exhaust camshaft are positioned right above horizontal camshaft centre line -2-.

–	Recesses of gear -3- in area of grooves are slightly more oriented above horizontal camshaftcentre line.

Caution

The camshaft clamp -T10477- must slide into position easily.

The camshaft clamp must not be positioned using any kind of hammer.

–	Insert camshaft clamp -T10477- to stop into camshafts and tighten bolt -arrow- by hand.

–	Loosen securing bolts of camshaft sprockets until sprockets can easily be rotated by hand.

Align marked gap -1- of camshaft adjuster -3- with lug -2- of camshaft housing.

Align marked tooth -1- of exhaust camshaft sprocket -3- with lug -2- of camshaft housing.

–	Markings -1- and -2- on camshaft sprockets are aligned as shown.

Groove -3- for assembly tool -T10476- is located on exhaust camshaft sprocket.

–	Insert assembly tool -T10476- between camshaft sprockets.

–	Arrows -1- on assembly tool are aligned with marks -2- on camshaft sprockets.

Note

When the assembly tool -T10476- is inserted, the marks -2- on the camshaft sprockets are slightly offset.

–	Dowel pin -1- of assembly tool -T10476- must engage in groove -2- of exhaust camshaft sprocket.

–	Hand-tighten belt tensioner -3- on cylinder head.

–	Hook -1- must be positioned in recess -2-.

–	Orientation of eccentric -4- of belt tensioner must be as shown.

Note

t	In this position the belt tensioner is completely free of tension.

t	When installing the toothed belt, ensure that the assembly tool -T10476- is correctly positioned between the camshaft sprockets.

–	Toothed belt must make full contact with crankshaft sprocket.

–	Check that crankshaft is set to TDC for No. 1 cylinder.

The crankshaft must make contact with the locking pin -T10340- in direction of engine rotation.

–	Fit toothed belt -1- onto belt tensioner -5- and camshaft sprocket -2-.

–	Then fit toothed belt on camshaft adjuster -3- and on idler roller -4-.

–	Remove assembly tool -T10476- from camshaft sprockets.

–	At first, rotate eccentric -1- in -direction of arrow- until adjustment pointer -2- is located approx. 10 mm to the right from adjustment window -3-.

–	Then rotate eccentric of belt tensioner back using hexagon socket insert at position -1- untiladjustment pointer -2- is exactly centred in adjustment window -3-.

–	Hold eccentric in that position using hexagon socket insert at position -1-.

–	Tighten securing bolt -4- to 25 Nm.

Note

t	When the engine has been rotated by hand or by engine operation, the position of the adjustmentpointer -2- might be slightly offset from the adjustment window -3-.

t	However, this has no relevant influence on the valve timing.

–	Secure camshaft adjuster and exhaust camshaft sprocket with counterhold -T10172-.

–	Tighten securing bolts -1- and -2- to 50 Nm.

Note

The securing bolts will be tightened with a further tightening angle of 90° at the end of the work sequence after the valve timing has been checked.

–	Remove locking pin -T10340- from above with lifting platform lowered.

–	Unscrew bolt -arrow- and remove camshaft clamp -T10477-.

–	Turn crankshaft 2 turns in direction of rotation of engine.

–	Screw locking pin -T10340- into crankcase as far as it will go.

Caution

The camshaft clamp -T10477- must slide into position easily.

The camshaft clamp must not be positioned using any kind of hammer.

–	Insert camshaft clamp -T10477- to stop into camshafts and tighten bolt by hand.

The valve timing is OK, if the camshaft clamp -T10477- can be pushed into the camshafts.

If the valve timing is not OK:

–	Repeat adjustment of valve timing.

–	Remove camshaft clamp -T10477-.

–	Secure camshaft adjuster and exhaust camshaft sprocket with counterhold -T10172-.

–	Turn securing bolts -1- and -2- 90° further.

–	Renew O-ring of plug if damaged.

–	Tighten camshaft adjuster plug -1- to 20 Nm.

–	Remove locking pin -T10340- from above with lifting platform lowered.

Caution

After completing work, it is essential to ensure that the locking pin -T10340- and thecamshaft clamp -T10477- have been removed.

Specified torques

Specified torque for crankcase plug: 30 Nm.
