Information
- For checking with the adjusting gauge, the timing adjustment must be correct.
3. To check the camshaft adjustment, insert adjusting gauge 9686 for camshaft into the camshaft slots (pulley side) (inscription on gauge pointing towards cylinder head cover). If the gauge cannot be inserted, rotate the crankshaft a further 360° and secure it again.
4. Unscrew two M6 x 12 hexagon-head bolts on the coolant pipe at cylinder side 4 - 6.
5. Remove primary chain tensioner (hexagon socket a/f 32).

Information
- To make it easier to remove the bearing cover, spray the sealing surface with anti-rust agent.
7. Unscrew M8 hexagon collar nut on the bearing cover of the intermediate shaft with special tool socket wrench 9110, while at the same time countering at the slotted threaded pin on the intermediate shaft with a screwdriver.

8. Unscrew the three M6 x 20 fastening screws (coated) on the intermediate-shaft flange. Replace screws during installation and clean thread in crankcase.
Information
- Remove bearing cover using special tool puller 9673. If this is not available, lever the bearing cover out carefully with two screwdrivers so as not to damage the sealing surfaces. Turning several times to the left and right loosens the bearing cover.
- After removing the bearing cover, do not press the threaded bolts of the intermediate shaft.
9. Position special tool puller 9673 at the bearing cover grooves and secure by turning the locking lever anticlockwise.
