Notes: Fig. 1 Securing tensioner in position before removing
- Using a hex key, turn toothed belt tensioning roller -1- clockwise 8 mm
in direction of arrow until tensioning lever -2- compresses tensioner -3-
far enough to enable a 2 mm dia. spring pin to be inserted in drilling
and in plunger.
The toothed belt tensioner is oil-damped and can only be compressed
slowly by applying gradual pressure. Use spring pin from 2024 A.
- Insert spring pin and release toothed belt tensioning roller.

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.
