Tappet pin
Rocking lever and pin check
1. Visually check the rocking lever to detect any
cracks, seizures or wear. Replace the rocking lev-
er if necessary.
2. If the contact surface between the cam and the
rocking lever is excessively worn, replace the rock-
ing lever.
3. Visually check the pin to detect any cracks, seiz-
ures or wear.
Replace the pin, if necessary.

4. Pin and rocking lever coupling
•
With a dial gauge, measure the rocking
lever inside diameter according to two
directions perpendicular to each other.
•
With a micrometer, measure the pin
outside diameter in the coupling posi-
tion with the rocking lever. Measure in
two directions perpendicular to each
other.
•
Calculate clearance by deducting the pin diameter from the rocking lever diameter.
MEASURE THE PIN OUTSIDE DIAMETER IN THE COUPLING POSITIONS OF EACH ROCKING
LEVER.
