5. Set piston of respective cylinder to "“bottom dead centre”".

6. Screw adapter T40012 into spark plug thread and connect compressed air of at least 6 bar.
7. Strike tight valve cotters using driftVAS 5161/3 and a plastic hammer.
8. Screw toothed pieceVAS 5161/6 with hooking forkVAS 5161/5 into centre tread of guide plateVAS 5161/19B.
9. Insert assembly cartridgeVAS 5161/8 into guide plateVAS 5161/19B.
10. Attach pressure forkVAS 5161/2 to snap-in deviceVAS 5161/6.
11. Screw toothed pieceVAS 5161/6 with hooking forkVAS 5161/5 into outer tread of guide plateVAS 5161/19B.
