5. Mount rivet press tool (5) on the new timing chain (2) such that the assembly insert (7) touches the new riveted link and the centering fork (1) can be pressed out.
6. Screw in thrust spindle (8) and press in new riveted link up to the stop. Remove centering fork (1).

   Ensure that riveted link and assembly insert (7) are aligned. Do not allow the centering fork (1) which is pressed out to drop into the timing case recess.

7. Remove pressure screw (8) and rivet press tool (5).
8. Remove assembly inserts (6, 7) from rivet press tool (5).
