Installation in reverse order.

Note: Replace the screws that are tightened by turning the specified angle. The flywheel with the timing rotor can only be installed in one position.

Insert stop "3067" into the hole in cylinder block "A".



Tightening torque

Removal and installation the crankshaft cover from the gearbox side

The checkpoint has been removed.

Note: For better understanding, the procedure is shown with the engine removed.

Remove the flywheel. Turn the crankshaft to "TDC" as follows. Unscrew the threaded plug of the "TDC" hole on the cylinder block. Screw the locking bolt "T10340" into the cylinder block until it stops and tighten to a torque of 30 Nm. Turn the crankshaft in the direction of engine rotation until it stops. The crankshaft counterweight is now adjacent to the locking bolt.

Note: The locking bolt "T10340" locks the crankshaft only in the working direction of rotation.

Caution! Risk of engine damage! If the locking bolt "T10340" cannot be screwed in completely, the crankshaft is not in the correct position. In this case, proceed as follows.

Loosen the locking screw. Turn the crankshaft 90° in the direction of engine rotation. Screw the locking bolt "T10340" into the cylinder block until it stops and tighten to a torque of 30 Nm. Continue turning the crankshaft in the direction of engine rotation until it stops. Remove the oil pan. Remove the engine speed sensor "C28" "arrow".





Unscrew bolts -1...6-.

Note: The cover is pressed off the crankshaft together with the timing rotor.

To press out, screw 3 M6x35 "arrows" screws into the crankshaft cover, alternately tightening each one no more than V2 turns. Remove the cover with the timing rotor.

Pressing in the cover with the driving rotor

Note: The crankshaft cover with PTFE lip seal is supplied with a support ring for the working edge. Do not remove this ring before installation, as it will act as a mandrel during installation. After removing the cover with the timing rotor from the packaging, do not remove the rotor from the cover and do not rotate it relative to the cover. The correct installation position of the timing rotor is ensured by the lock of the "T10134" mounting device. The cover, lip seal and timing rotor form a single unit and should only be replaced as an assembly. The correct installation position of the "T10134" device is ensured by the installation pin, which enters the threaded hole in the crankshaft.

Installation of device "T10134"

A. Lead screw flat
B. Nut
C. Body
D. Retainer
E. Hexagon socket head cap screw
F. Guide pin for diesel engines (black pen)
G. Guide pin for gasoline engines (red pen)

A. Install the cover with the timing rotor on the mounting device "T10134"

Screw nut "B" almost to the chamfer "A" of the lead screw shank. Clamp the mounting device "T10134" in a vice in the area of the clamping surface "A" of the lead screw. Pressing on the housing "C", move it down so that it rests against nut "B" "arrow". The inner part and the housing of the device must be at the same level.



Remove the safety lock "arrow" from the new crankshaft cover.

Note: Do not turn the timing rotor out of the crankshaft cover or remove it.

The stop hole "A" on the timing rotor "C" must be located opposite the mark "B" on the crankshaft cover.



Place the cover on a clean flat surface with the front (outer) side down. Press the support ring "A" down along the "arrow" so that it rests against the flat surface.



The top edge of the support ring and the front edge of the crankshaft cover must be flush with the "arrow".





Place the cover with the front side on the "T10134" device so that the locking pin "B" enters the hole "A" of the timing rotor. The cover must lie flat on the mounting device.



Tighten the 3 knurled head screws "A" while constantly pressing the cover and support ring "B" against the surface of the "T10134" fixture so that the locking pin cannot slip out of the hole in the timing rotor.

Note: When installing the cover, the timing rotor must remain secured in the mounting device at all times.

B. Installing the "T10134" device with a cover on the crankshaft flange

The crankshaft flange must be degreased. The crankshaft is at "TDC". Unscrew nut "B" to the end of the lead screw. Press the lead screw of the "T10134" device along the "arrow" so that nut "B" rests against housing "A". Align the flat side of the housing relative to the pressed plane of the cylinder block from the oil pan side.



Attach the "T10134" device to the crankshaft flange. Screw the Allen screws "A" into the crankshaft flange approximately 5 threads.



Screw 2 M6x35 mm screws into the cylinder block -pos. A-, which will act as cover guides.

C. Screwing the mounting device "T10134" to the crankshaft flange

Move the housing of the mounting device "C" by hand in the direction of the "arrow" until the support ring "B" rests against the crankshaft flange "A". Insert the guide pin for gasoline engines (red pen) "F" into the crankshaft hole. Thus, the timing rotor will take the mounting position.

Note: Never insert a diesel guide pin into the threaded hole of the crankshaft (black pen) "D".

Tighten both Allen screws of the mounting fixture. Screw nut "E" onto the lead screw until it touches the body of fixture "C".

D. Pressing the timing rotor onto the crankshaft flange using the mounting device "T10134"

Tighten the nut of the mounting device "T10134" to a torque of 35 Nm. After tightening the nut to a torque of 35 Nm, there should still be a small gap between the cylinder block and the cover.

E. Checking the mounting position of the timing rotor on the crankshaft

Loosen nut "E" to the end of the lead screw. Loosen both screws "A" from the cylinder block. Loosen knurled head screws "B" from the crankshaft cover. Remove mounting device "T10134" from the crankshaft flange by unscrewing the Allen screws from the crankshaft flange. Remove the retaining ring.



Install the depth gauge "VAS 6082" on the crankshaft flange.



Measure the protrusion "a" of the crankshaft flange "A" relative to the timing rotor "B". Nominal value: dimension "a" = 0.5 mm. If the nominal value is too small, press the timing rotor in place. If the specified value is reached, continue installation.

F. Additional pressing of the master rotor

Secure the mounting device "T10134" "pos. A" to the crankshaft flange, tightening the Allen bolts by hand. Move the device "T10134" toward the crankshaft cover by hand.



Screw nut "E" onto the lead screw until it is in contact with the body of device "C". Tighten the nut of mounting device "T10134" to a torque of 40 N·m. Check the mounting position of the timing rotor on the crankshaft again. If the nominal value is too low, tighten the nut of mounting device "T10134" to a torque of 45 N·m. Check the mounting position of the timing rotor on the crankshaft again.

Assembly

Tighten the crankshaft cover mounting screws crosswise. Install the oil pan. Install the intermediate plate. Install the flywheel.
