SERVICE.
2. Rotate the plungers so the outer plungers are
projecting the same distance from the crankcase.

4. Start the head onto the plungers and, using a soft
mallet, tap the head evenly until it comes in contact
with the crankcase.

crankcase. Do not forget the lock washer on each
screw.
6. Tighten all cap screws by hand.
