NOTE: Always use original OEM parts to make sure that the
valve functions properly.
1. Follow the steps in all the WARNING sections above
before performing any work on the valve.
2. Open the valve.
3. The insert design requires that the insert (2) be
unthreaded in a counter clockwise motion using the
following method utilizing the insert field wrench.
Assemble the field wrench as follows (see Figures 5
and 19):
A. Place the driver (A) into the insert (2) slots.
B. Put the plate (C) on top of the driver (A).
C. Place the studs (E) through the plate (C) and flange
holes. Thread the nuts (F) onto the stud below the
flange.

4. Place a pipe or rod through the driver (A) and loosen
the insert (2) by turning counterclockwise.
5. Remove the tool and lift out the insert (2).
6. Place the valve in the vertical position with the insert
end up.
7. Rotate the stem (4) so that the ball is in the closed posi-
tion for removal. If the ball (3) does not swing free from
the body, with the ball in the fully closed position, use
a piece of wood or some other soft material to gently
tap the ball (from the end opposite the body cap). This
should loosen the ball so that it can be pivoted free
of the stem (4). Lift out the body seal (6), seat (5), and
ball (3). The bottom grounding spring (71), located in
bottom of the stem (4), may fall out this time. If the
spring does not fall out with the stem, remove it from
the stem to prevent it from being lost.
8. Carefully remove the bottom seat (5) out of the body,
BEING CAREFUL NOT TO SCRATCH THE BODY
SEALING SURFACE BEHIND THE SEAT .
9. If the valve has grounded option, remove retaining
ring (72) and top grounding spring (70) from stem (4).
10. Remove the stud nuts (30), disc springs (31), and com-
pression plate (20). Pay careful attention to the orien-
tation of the disc springs (31) and make sure they are
in the same orientation during re-assembly.
11. Press the stem (4) from the top into the valve body and
remove it through the insert end of the body.
12. Remove and discard the thrust bearings (13), and
secondary stem seal (7), BEING CAREFUL NOT TO
SCRATCH ANY SEALING SURFACES IN THE BODY .
13. Remove the stem seals (8), BEING CAREFUL NOT
TO SCRATCH ANY SEALING SURFACE INSIDE THE
STEM BORE .
