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

4 Slowly rotate engine in direction of rotation of engine until the ends of the new timing chain (2) can be connected.
Always keep old timing chain (1) and the timing chain (2) under tension otherwise they can skip and this will damage the engine.
During the insertion procedure, 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 hold-down device (010) in mesh with camshaft sprockets.

5 Remove assembly link (7.1), assembly outer plate (7.2) , assembly locking element (7.3) and old timing chain (1).
The fact that the assembly connecting link (7.1) , assembly outer plate (7.2) assembly locking element (7.3) are just assembly aids and are not suitable for running the engine means that the new timing chain (2) could break leading to damage to the engine.
