Removing –  Remove the Poly V-belt → Chapter. –  Loosen the pulley securing bolt. Immobilise the pulley using the retention tool -3415-.

Installing –  Unscrew the bolts -1- and disconnect the retainer of the coolant hose -2-.   Note t  Make sure that all contact surfaces from the securing bolt to the crankshaft sprocket are free of oil and grease. t  Always use a new bolt. –  Tighten by hand the belt pulley with a new fastening bolt.

–  Remove locking bolt -arrow- on the crankshaft sump.   Note t  The securing bolt prevents the crankshaft from turning while tightening the tightening torque. t  The tightening torque could not be correct because of this. –  Tighten the securing screw -T10340- until the end point in the crankshaft sump.   Caution If the locking bolt -T10340- cannot be screwed until the end point, the crankshaft is not in the right position. In this case, proceed as follows: –  Remove the locking pin. –  Turn the crankshaft by a 1/4 90° rotation in the direction of the operation of the engine. –  Tighten the securing screw -T10340- until the end point in the crankshaft sump. –  Tighten the securing bolts securing bolts -T10340- to 30 Nm. –  Turn the crankshaft to the end point in the direction of the operation of the engine.

Use the securing screw -T10340- to immobilise the crankshaft in the direction of operation of the engine.   Caution To tighten the securing bolt, use the counterholder -3415- to prevent any damages to the securing bolt. Tightening torque: 150 Nm and then turn 180° further Immobilise the pulley using the retention tool -3415-.

–  Undo the fastening bolt -T10340- of the crankshaft sump. –  Screw the locking bolt in the crankshaft sump.

Tightening torque: 30 Nm

–  Assemble the retainer of the coolant hose -2- and tighten the bolts -1-. Tightening torque Bolt M6 = 10 Nm M8 bolt = 20 Nm –  Install poly V-belt → Chapter. Further assembly is basically the reverse of the dismantling sequence.
