Fitting timing chain

Installing timing chain

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:
^ The rolling direction of the timing chain must always be the same.
^ If the timing chain is to be reused, the rolling direction of the timing chain must be marked before it is removed.

Note: If the timing chain has to be removed or replaced, check the guide and tensioning rails for wear and scoring and replace them if necessary. Camshaft timing gears and camshaft adjusters must be installed and it must be possible to turn them.

1. Place timing chain loosely on all sprockets. Ensure that the timing chain is in the correct position on the guide rails.
2. Fit guide and tensioning rails.





3. Place guide rails between the camshafts on the threaded pegs. To do this, let timing chain dangle between the camshafts.

Subsequent work

1. Install chain case lid.
2. Set timing of camshafts.
3. Install cover for camshaft housing.
4. Install engine.
