Cover over timing case recess with a clean cloth.
The timing case recess must be secured against parts falling down. Parts that have fallen into the timing case recess must be removed.
Connect new timing chain (2) and old timing chain (1) together using the assembly link (01).
Fit lock on assembly link (01) in the direction opposite to that in which the timing chain is drawn; otherwise it could get jammed on the slide rails and come off when the timing chain is drawn.

Remove rags from timing case recess.
Otherwise, they could get pulled into the timing case recess when the engine is cranked.
Turn crankshaft slowly in the engine's direction of rotation (arrow) and draw in the new timing chain (2) until the ends of the new timing chain (2) can be connected.
As the new timing chain (2) is being drawn in (arrows), pull out the end of the old timing chain (1) evenly as it becomes free.
Cover over timing case recess with a clean cloth.
The timing case recess must be secured against parts falling down. Parts that have fallen into the timing case recess must be removed.
Detach assembly link (01), and separate old timing chain (1) from new timing chain (2).
The assembly link (01) must be removed. The assembly link is only an aid for assembly and is not suitable for engine operation.
