Fitting timing chain
Installing timing chain

ATTENTION: Engine damage due to turning the crankshaft against the running direction (engine assembled)!
--> Never turn the engine against the running direction when the timing drive mechanism is fitted (timing chain may jump over).
--> Proceed carefully while working as otherwise engine damage may occur.
--> Only turn the engine on the crankshaft and never on the camshaft as the timing chain can jump over.
--> After working on the camshaft timing gears, the timing must be adjusted.
--> Please observe the general warning notes and working regulations --> '10 The most important working regulations and warning notes'

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.

Guide Rails Between Camshafts:

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

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