Special tools and workshop equipment required

t	Spark plug socket and extension -3122 B-

t	Counterhold -3415- with dowel pins -3415/1-

t	Dial gauge -VAS 6079-

t	Extractor -T10094 A-

t	Dial gauge adapter -T10170-

t	Securing bolt -T10340-

Pulley for the crankshaft: Removing → Anchor Pulley for the crankshaft: Fitting → Anchor Removing Proceed as follows:   Note t  Use locking pin -T10340- in addition to counterhold tool -3415- to prevent slipping and to make sure the tightening torque for the crankshaft pulley bolt is maintained. t  The locking pin -T10340- locks the crankshaft only in the direction of engine rotation.   Caution Risk of damage to engine. Locking pin -T10340- must be screwed in with crankshaft at „TDC“ position.

–  Remove poly V-belt → Chapter. –  Disengage coolant hose -1- at engine cover panel. –  Pull out the dipstick.-2-. –  Unscrew bolts -arrows- and remove engine cover panel.

–  Apply the extractor -T10094 A- on the ignition coil 1 -arrow-, using theExtractor -T10118-, pull out ignition coil and at the same time unplug electrical connector at ignition coil for cylinder 1. –  Remove spark plug for cylinder 1 with spark plug socket and extension -3122 B-.

–  Screw adapter for dial gauge -T10170- into spark plug hole as far as the stop. –  Insert dial gauge -VAS 6079- with extension -T10170/1- as far as the stop and secure using locking nut -arrow-. –  Rotate crankshaft in normal direction of rotation to „TDC“. l  „TDC“ = maximum measured value on dial gauge.

–  Remove bolts -1- and -3- and take off bracket -2- for coolant pipe (right-side).

–  Unscrew plug -arrow- for „TDC“ hole on cylinder block.

–  Screw locking pin -T10340- into cylinder block as far as stop and tighten to 30 Nm.   Note The locking pin -T10340- locks the crankshaft only in the direction of engine rotation.

Caution Risk of damage to engine. To prevent the crankshaft chain sprocket from slipping off the drive lug, do not rotate the crankshaft after the poly V-belt pulley has been detached. –  Loosen the bolt for the poly V-belt pulley, for this purpose, counterhold using the counterhold tool -3415- with dowel pin -3415/1-. –  Remove the bolt and take off the poly V-belt pulley. Installing l  Tightening torques → Chapter   Note t  Replace the bolts of the Poly V-belt pulley. t  All contact surfaces between bolt, Poly V-belt pulley, bush and chain sprocket must be free of oil and grease. –  Fit poly V-belt pulley, lubricate threads of bolt for poly V-belt pulley with oil and screw in by hand until bolt makes contact.   Caution Risk of damage to engine. t  Use dial gauge to check „TDC“ position of crankshaft. Crankshaft must only be brought into contact with locking pin -T10340- from „TDC“ position. t  Also use counterhold tool -3415- and pin -3415/1- to counterhold poly V-belt pulley when tightening bolt.

–  Turn crankshaft in direction of engine rotation until it makes contact with locking pin -T10340-. –  Tighten bolt for poly V-belt pulley (counterhold with counterhold tool -3415- and pin -3415/1-).

–  Remove locking pin -T10340-.

–  Renew seal on plug for „TDC“ drilling. –  Tighten the screw plug for -arrow- for the borehole „OT“ to 30 Nm. The remaining installation steps are carried out in reverse sequence - note the following points: –  Mount the engine cover panel.

–  Tighten bolts -arrows- to 10 Nm. –  Install poly V-belt → Chapter.
