z Place the depth measuring screw on the contact

surface of the crankcase and keep it pressed against

the stop.

Turn the depth measuring screw until the probe is

touching the roller tappet.

z In hydro-roller tappets, the working piston in the

roller tappet (1) must be pressed down

(approx. 1 mm)

to determine the total depth dimension by turning on

the depth measuring screw to the stop (arrow).

z Measure, read and note the depth dimension "A"

from the crankcase rest to the plate spring rest of the

roller tappet.

Note

- The crankcase rest must be clean.

- Example: 60.25 mm
