5

Press clearance compensation element (11) of the related cylinder with a drift (2 mm diameter) out of the roller-type rocker arm (9)

 Do not use a magnet!

The slide surface on the valve clearance compensation element (11) would get magnetized. This can cause minute iron chips to accumulate, which in turn can damage the compensation element (11) and the cam.

 Installation: The small plate (10) at the top of the roller-type rocker arm (9) must point to the compensation element with the slits facing downwards (11). Compensation elements (11) which have not been replaced must be reinstalled at the same point.
