TROUBLESHOOTING
3. Verify check valve function by carefully
inserting a small screwdriver, drift pin or
similar type of tool into the control piston
bore and pushing on the check valve ball.
There should be spring tension against the
check ball, and the ball travel should be
approximately 3/16 inch (4.763 mm). If the
check ball does not move down freely, and if
spring tension does not return the check ball
to its seat, replace the rocker arm assembly.
Check valve must not be over stroked. This could
damage the valve and/or rocker arm.
104
Figure 104 — Verifying Check Valve Function
The check valve is not replaceable. Any problems
found with the check valve require that the
complete rocker arm assembly be replaced.
4. If the check valve, control piston and control
piston spring are OK, remove the rocker arm
and check the hydraulic actuator plunger as
follows:
a.
Make sure the plunger retaining ring is
in place.
b.
Spring tension holds the plunger down
against the retaining ring. Check for a
broken spring by making sure the
plunger is seated against the retaining
ring.
c.
Push the plunger to make sure it moves
freely in the bore and that spring
tension seats the plunger against the
retaining ring. If the plunger sticks or
binds in the bore, or if spring tension
does not keep the plunger seated
against the retaining ring, replace the
rocker arm.
105
Figure 105 — Check Plunger Movement and Plunger
Spring Tension
The plunger is not serviceable. Any problems
found with the plunger or plunger spring require
that the complete rocker arm assembly be
replaced. DO NOT attempt to remove any
components from the rocker arm with the
exception of those shown in Figure 103.
