Removing and installing crankshaft-belt pulley Special tools and workshop equipment required t  Counterholder -T30004 (3415)- t  Bolt -T30004/2 (3415/2)- t  Locating screw -T10340-   Note t  In order to avoid that the tightening torque of the fixing screw for the crankshaft-belt pulley is inaccurate due to slip, the fixing screw -T10340- must be used in addition to the counterholder -T30004-. t  The crankshaft is only locked in direction of rotation of engine using the fixing screw -T10340-.   Caution Risk of engine damage! t  The fixing screw -T10340- must not be used to slacken the fixing screw for the crankshaft-belt pulley - only for tightening! t  The locating screw -T10340- must only be screwed in the „TDC“ position of the crankshaft. Removing –  Remove V-ribbed belt → Chapter. –  Rotate the crankshaft in direction of rotation of engine on TDC for cylinder 1 → Chapter.

–  Counterhold belt pulley with counterholder -T30004 (3415)- with bolt -T30004/2 (3415/2)- and release fixing screw for belt pulley. –  Remove the belt pulley together with the diamond coated washer. Install Vehicles with auxiliary heating.

–  Screw out the screws -1 and 2- of the brackets for the coolant pipes for the auxiliary heating -3-. Continued for all vehicles

–  Release fixing screws -1- and remove bracket for coolant pipe -2-.   Note t  Make sure that all clamping surfaces of the fixing screw are free of oil and grease up to the crankshaft chain sprocket. t  Always use a new screw of the crankshaft belt pulley. –  Install the belt pulley together with the diamond coated washer and tighten the new fixing screw by hand.

–  Release screw plug -arrow- at cylinder block.   Note Using the fixing screw should prevent the crankshaft from turning when tightening to the tightening torque.

–  Turn the fixing screw -T10340- up to the stop in the cylinder block.   Caution If the fixing screw -T10340 - cannot be screwed in up to the stop, the crankshaft is not in the correct position! In this case proceed as described below. –  Unscrew the fixing screw. –  Turn crankshaft 90° (1/4 turn) in direction of rotation of engine. –  Turn the fixing screw -T10340- up to the stop in the cylinder block. –  Tighten fixing screw -T10340- to 30 Nm. –  Turn crankshaft up to the stop in direction of rotation of engine. The crankshaft is locked in direction of rotation of engine with the fixing screw -T10340-.   Caution Absolutely use the counterholder -T30004 (3415)- with bolt -T30004/2 (3415/2)- when tightening the fixing screw of the belt pulley in order to avoid damage to the fixing screw. –  Counterhold belt pulley with counterholder -T30004 (3415)- with bolt -T30004/2 (3415/2)- and tighten fixing screw for belt pulley. Tightening torque: 150 Nm + torque a further 1/2 turn (180°)

–  Release the fixing screw -T10340- from the cylinder block.

–  Screw the screw plug again into the cylinder block. Tightening torque: 30 Nm.

–  Install bracket for coolant pipe -2- and tighten screws -1-. Tightening torque Screw M6 = 10 Nm Screw M8 = 20 Nm –  Install the V-ribbed belt → Chapter. Further installation occurs in a similar way in reverse order to removal.
