Oil check valves, replacing


Note:
If irregular valve noise occurs repeatedly during
short journeys and disappears after extended
driving, the oil check valves must be replaced.

All cable ties which are released or cut open
when removing the engine must be replaced in
the same position when installing the engine.
Catch drained-off coolant in a clean container
for re-use or disposal.
Replace all gaskets and seals.

Notes:

Mark the direction of rotation of the toothed belt
with chalk or felt pen before removing. A used
belt can break if it rotates in the wrong direction
when reinstalled.
The toothed belt tensioning element is oil-
damped and can therefore only be compressed
slowly by applying constant pressure.

- Using a hex key, turn toothed belt tensioning roller -1- clockwise 8 mm
in direction of arrow until tensioning lever -2- compresses tensioning
element -3- sufficiently to enable special tool T 400 11 to be installed in
drilling and in plunger.
- Insert special tool T 400 11 and release toothed belt tensioning roller.
- Insert camshaft clamp 3391 in the securing plates of the two
camshafts.
- Loosen both camshaft bolts and remove approx. 5 turns.
- Take out camshaft clamp 3391.

- Pull off both camshaft sprockets with special tool T40001.
