Removing timing chains

ATTENTION Damage to engine by turning crankshaft against the rotation direction of the engine (engine assembled)!
^ Never rotate crankshaft against the operating direction if the timing drive mechanism is mounted (timing chain jumps over).
^ Proceed carefully while working as otherwise the engine can be damaged.
^ Always turn the engine on the crankshaft and never on the camshaft as the timing chain may jump over.
^ After working on the camshaft wheels, the timing must be set.
^ Please observe the general warning notes and working regulations

Note:
^ Check all components, such as timing chains, sprockets, locking pins and chamfers for wear or damage. Replace faulty components.
^ Always replace all fastening screws for the sprockets.





^ Before removal, mark the timing chain rolling direction and timing chains with a colored pen. Retain timing chain rolling direction and timing chains during re-installation. Never use a prick punch or file for marking.





1. Position crankshaft to the TDC of cylinder 1 TDC of cylinder.
2. Remove top and bottom chain case lid.





3. Block crankshaft using arm bracket T10069 with the help of an assistant.
4. Loosen M12 x 40 fastening screw -14- on the intermediate shaft.








5. Remove timing chain between intermediate shaft and camshafts. To do this, remove black guide rail -1- by loosening the two M8 x 43 fastening screws -arrows- and remove timing chain up to camshaft.

Note:
^ The chain tensioner between the crankshaft and intermediate shaft is spring-tensioned.





^ The chain tensioner between the crankshaft and intermediate shaft can be reset. To do this, unblock the locking teeth in the side bore of the chain tensioner -A- using a small screwdriver and press the tensioning rail against the chain tensioner.

6. Remove chain tensioner for timing chain between crankshaft and intermediate shaft. To do this, loosen two fastening screws (M6 x 24) and remove chain tensioner with tensioning rail attached.
7. Remove timing chain with intermediate shaft sprocket.
