one side. |
|
|
|
| – |
Lay wiring harness to one side
-arrows-. |
| – |
Unscrew bolts -1, 3- and remove
cover -2- for toothed belt for
coolant pump. |
|
|
|
| – |
Unscrew bolts -arrows- and
detach sealing cap -1-. |
| Rotate crankshaft to “TDC” as follows: |
| – |
Remove ignition coil 1 with output stage -N70- and cylinder
1 spark plug
→ Chapter. |
| – |
Insert a screwdriver with a shaft length of at least 250 mm
into spark plug hole so that it contact piston crown. |
| – |
Turn the crankshaft in the normal direction of rotation
until the piston in cylinder 1 shows “BDC”. |
|
|
|
| The screwdriver moves in the
-direction of the arrow-. |
|
|
|
| – |
Turn the crankshaft further, until the screwdriver has moved
-30 mm- in the
-direction of the arrows- |
|
|
|
| – |
Unscrew plug for “TDC” hole in cylinder block. |
| – |
Screw locking pin -T10340- into cylinder block as far as
stop and tighten to 30 Nm. |
| – |
Rotate crankshaft in normal direction of rotation as far as
stop. |
| The locking pin now rests against the crank web. |
 Note
| Locking pin -T10340- locks crankshaft in direction of engine
rotation only. |
| If locking pin -T10340- cannot be screwed in as far as stop,
this indicates that crankshaft is not in the correct position! |
| In this case, proceed as follows: |
| Turn crankshaft 90° in direction of engine rotation. |
| Screw locking pin -T10340- into cylinder block as far as
stop and tighten to 30 Nm. |
| Turn crankshaft in direction of engine rotation as far as
stop. |
| The asymmetrically positioned grooves on gearbox end of both
camshafts -arrows, upper figure-
must be above the horizontal centre line, as shown in figure. |
|
|
|
| The grooves on the exhaust camshaft
-upper arrows- can be accessed through the recesses in
toothed belt pulley for coolant pump. |
| On the inlet camshaft the grooves
-lower arrows- must also be positioned right above
horizontal camshaft centre line. |
| – |
If camshafts are not positioned as described, unscrew
locking pin -T10340-, turn crankshaft one rotation further and
return to “TDC” position. |
Note
| The camshaft clamp -T10494- must slide into position easily. |
| Do not knock camshaft clamp into place with any kind of
tool. |
| If the camshaft clamp -T10494- does not easily slide into
position: |
|
|
|
| – |
Use assembly tool -T10487- to push against toothed belt in
-direction of arrow-. |
|
|
|
| – |
Insert camshaft clamp -T10494- as far as stop into camshaft. |
| – |
Tighten bolt -arrow- by hand. |
| If camshaft clamp cannot be fitted: |
| – |
Adjust valve timing: removing toothed belt from camshafts
→ Chapter. |
| If camshaft clamp can be fitted: |
| After completing work, check that locking pin -T10340- and
camshaft clamp -T10494- have been removed. |
| Further assembly is carried out in the reverse order of
removal. |
Note
| Renew bolts that are tightened with specified tightening
angle. |
| Renew O-ring of plug if damaged. |
