2. Remove valve rocker arms and push-
rods.
3. Remove valve lifters. Place valve lift
ers, rocker arms and pushrods in order so that
they may be installed in original location.
4. Coat foot of valve lifters with Molvr
kote® or its equivalent and install valve lift
ers. Make sure lifter foot is convex. A suit
able hydraulic lifter removal and installation
tool makes the job easier.
5. Reassemble in reverse of removal pro
cedures. Check valve adjustment.

3. Remove the plunger, ball check valve
assembly and the plunger spring.
4. Remove the ball check valve and spring
by prying the ball retainer loose from the
plunger with the blade of a small screw driver.
5. Thoroughly clean all parts in cleaning
solvent, and inspect them carefully. If any
parts are damaged or worn, the entire lifter
assembly should be replaced. If the lifter body
wall is scuffed or worn, inspect the cylinder
block lifter bore. If the bottom of the lifter is
scuffed or worn, inspect the camshaft lobe. If
the push rod seat is scuffed or worn, inspect
the push rod. An additive containing EP lube,
such as EOS, should always be added to
crankcase oil for run-in when any new cam
shaft or lifters are installed. All damaged or
worn lifters should be replaced.
NOTE:
For proper lifter rotation during
engine operation, lifter foot must be con-
vex.
6. Place the check ball on small hole in
bottom of the plunger.

retainer into position in plunger with the blade
of a small screw driver.
8. Place the plunger spring over the ball
retainer and slide the lifter body over the
spring and plunger, being careful to line up
the oil feed holes in the lifter body and
plunger.
