elements for reinstallation. |
| – |
Remove roller rocker fingers together with compensation
elements and place them on a clean surface. |
 Note
| Renew bolts that are tightened with specified tightening
angle. |
| Renew gasket and seal with oil strainer. |
| – |
Check “TDC” position of camshaft and crankshaft: |
|
|
|
| Camshaft clamp -T10504- fitted on camshaft housing. |
| Engine codes CHPA, CMBA, CPVA, CXSA, CZDA, CZCA, CPVB |
|
|
|
| Camshaft clamp -T10494- must be attached to camshaft
housing. |
Risk of damage to valve gear caused by camshafts being moved in axial
direction.Never move camshafts in axial direction when turning them.
|
|
|
| Locking pin -T10340- screwed into cylinder block as far as
stop and tightened to 30 Nm. |
| Crankshaft has been turned in direction of engine rotation
until it rests against locking pin -T10340- = “TDC” position. |
|
|
|
| – |
Check, if all roller rocker fingers are seated properly on
valve stem end and if they are clipped into the respective
compensation element. |
Note
| The oil strainer is fitted only if the cylinder head has the
appropriate recess. |
| Cylinder heads with recess do not require an oil strainer. |

| – |
Screw 2 studs -items 2, 4-
(e.g. -T10288/4-) into cylinder head. |
| – |
Carefully lower camshaft housing -3-
vertically onto studs in cylinder head. |
Note
| Ensure that camshaft housing is not canted. |
| – |
Tighten bolts for camshaft housing. |
| Specified torque and tightening sequence, engine codes CPTA,

| Avoid damage to valves and piston crowns after working on
valve gear. |
| Turn the engine carefully at least 2 rotations to ensure
that none of the valves make contact when the starter is
operated. |
