Camshaft Housing, Removing And Installing: Installing
Replace the bolts that were tightened with an additional turn.
Replace the gasket and the seal with the oil screen.
-- Check the "TDC" position of the camshaft and crankshaft:
- Never move the camshafts axially when turning.
- :T10340
installed all the way into the cylinder block and tightened to 30 Nm.
- Crankshaft in direction of engine rotation touching the :T10340 = "TDC" position.
-- Make sure all roller rocker levers are mounted correctly on the valve shaft ends and are clipped to the lifters.
The oil screen may only be installed if the cylinder head has the corresponding recess for it.
Cylinder heads without a recess do not require an oil screen.
-- Install the seal and oil screen -2- in the cylinder head -1-.
-- Place the seal on the alignment pins -arrows-.
-- Install the two threaded pins -2 and 4-, for example the :T10288/4 , into the cylinder head.
-- Mount the camshaft housing -3- carefully vertically onto the threaded pins in the cylinder head from above.
Make sure the camshaft housing is not tilted.
-- Tighten the bolts for the camshaft housing. Refer to Figure.
Further installation is performed in reverse order of removal, while noting the following:
-- Install the high pressure pipe. Refer to HIGH PRESSURE PIPE, REMOVING AND INSTALLING .
-- Install the toothed belt (adjust valve timing). Refer to TOOTHED BELT, REMOVING FROM CAMSHAFTS .
-- Install the ignition coils. Refer to IGNITION COILS WITH POWER OUTPUT STAGES, REMOVING AND INSTALLING .
-- Install the coolant pump. Refer to COOLANT PUMP, REMOVING AND INSTALLING .
-- Connections and wire routing. Refer to the Appropriate Wiring Diagram.
Risk of damaging the valves and piston crowns after working on valvetrain.
- To ensure that the vales do not make contact when starting, carefully rotate the engine at least two full revolutions.
