5 | Remove the chain tensioner | ||
Do not attach cable tie. | |||
6 | Loosen bolts (3) | For this purpose, secure respective camshaft at hexagon with open-end wrench against turning. A helper is required. | |
7 | Remove both camshaft positioners (5, 6) | To do so, remove screws/bolts (3) and remove timing chain (4) from camshaft positioners (5, 6). | |
| Install | ||
8 | Mount camshaft positioner (6) onto camshaft | To do so, install the camshaft positioner (6) together with the timing chain (4) and screw in a new screw/bolt (3). Position timing chain (4) in front of the toothing of the camshaft positioner (6). Do not screw in screw/bolt (3) completely yet. It must still be possible to rotate the camshaft positioner (6). | |
9 | Install camshaft positioner (5) on camshaft | To do so, mount the camshaft positioner (5) and screw in a new screw/bolt (3). Position timing chain (4) on verge of toothing of camshaft positioner (5). Do not screw in screw/bolt (3) completely yet. It must still be possible to turn camshaft positioner (5). | |
10 | Place timing chain (4) on the camshaft positioner (6) | To do so, align color coding (D6) with marking (C6). | |
11 | Align camshaft positioner (6) with camshaft | For this purpose, turn camshaft at hexagon until guide pin (B) engages in camshaft positioner (6) and fully screw in screw (3). Do not tighten the screw/bolt (3) yet. | |
12 | Mount timing chain (4) on camshaft positioner (5) | To do so, align color coding (D5) with marking (C5). | |
13 | Align camshaft positioner (5) with camshaft | For this purpose, turn camshaft at hexagon until guide pin (A) engages in camshaft positioner (5) and fully screw in screw (3). Do not tighten the screw/bolt (3) yet. | |
14 | Tighten screw/bolts (3) | For this purpose, secure respective camshaft at hexagon with open-end wrench against turning. A helper is required. | |
