f. Assemble Piston Rod and Head Cover into
VVCP Head.
g. Install and tighten Head Cover Bolts to specified
torque in Bolt Torque Table.
h. Install Seal Washer onto Piston Rod.

specified torque in Bolt Torque Table. Confirm
no leak is present. Tighten as necessary.
j. Install second Seal Washer onto Piston Rod.
k. Thread Rod Cover onto Piston Rod, and tighten
to specified torque in Bolt Torque Table.
Confirm no leak is present. Tighten as

THE PROPER PRECAUTIONS ARE NOT
TAKEN.
b. Loosen and remove Rod Cover.
c. Loosen Locknut far enough along Piston Rod to
make the proper adjustments.
d. Use a wrench across flats on end of Piston Rod,
and adjust Clockwise to reduce additional
Clearance Volume, and Counter-Clockwise to
increase Clearance Volume.
e. Tighten Locknut.
f. Thread Rod Cover onto Piston Rod, and tighten.
11. PRE-STARTUP
a. Fill the crankcase with oil. Refer to the
"Crankcase Lubrication" section. Squirt oil into
