Cover timing case recess and cylinder head with clean rag.
Parts, which have fallen into the timing case recess or the cylinder head must be removed in order to avoid damage to the engine.
Connect the new timing chain (2) and the old timing chain (1) with the assembly link (7.1), the outer assembly plate (7.2) and the assembly locking element (7.3), and secure.
The positioning bore (arrow) of the new timing chain (2) must be visible.
Remove rag from timing case recess and cylinder head.
Otherwise when cranking the engine, this can be drawn into the timing case recess.

Slowly turn the engine at the center bolt of the crankshaft in the in direction of engine rotation until the ends of the new timing chain (2) can be connected.
During the insertion procedure, the old and new timing chains (1, 2) must be fed by a second person in and out of the timing case slot. The old and new timing chains (1, 2) are always held by the hold-down device (010) in mesh with the camshaft sprockets.

Remove the assembly clip-type fastener (7.1), the outer assembly plate (7.2), the assembly locking element (7.3) and the old timing chain (1).
As the assembly clip-type fastener (7.1), the outer assembly plate (7.2) and the assembly locking element (7.3) are designed to assist with assembly only and are not suitable for engine running, the new timing chain (2) can rip, which would lead to engine damage.
