HYDRAULIC VALVE TAPPET —
INSPECTION
Step Procedure
1 Check visually for damage and wear.
NOTE
The hydraulic valve tappet rotates during opera-
tion, so there is a uniform, rotational symmetri-
cal support pattern on the cam contact face.
NOTE
If the tappet does not rotate, uneven wear oc-
curs on the contact face. If there are uneven
smooth areas, corroded areas/pitting, the tappet
must be replaced.
ATTENTION
The hydraulic valve tappet must not be re-
ground on the end!
ATTENTION
Disassembly of the hydraulic valve tappet is
neither permissible nor necessary.
