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 hexagon 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 a 2mm dia. spring pin to be
installed in drilling and in plunger.
- Insert spring pin and release toothed belt tensioning roller.
Use spring pin from 2024 A.
- 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.
