5. Place the shutoff handle in the open position, as shown on the assembly drawing, and remove the valve

ball (Item 3) by pulling it straight out. Replace the ball if it has any significant scratches or gouges.

6. Remove the actuator shaft screw (Item 10) from one side of the shutoff assembly only.

7. Remove the old actuator shaft (Item 4) by pushing it from the outside into the waterway of the shutoff.

Remove and discard the old actuator shaft.

8. Place a new o-ring (Item 9) on a new actuator shaft (Item 4), lightly coat the o-ring and actuator shaft on

both sides of o-ring with grease (Dow Corning #7), and insert the square end of the actuator shaft
through the shutoff body (Item 8) and into the square hole in the shutoff handle(Item 16). The blade of
the actuator that drives the valve ball should be aligned with the blade of the actuator on the opposite
side (both blades should align with the centerline of the valve waterway when the shutoff handle is in
the open position).

9. Apply #262 Loctite to the thread and reinstall and tighten the actuator shaft screw (Item 10).

10. Remove the actuator shaft screw (Item 10) from the other side of the shutoff assembly.

11. Remove the remaining old actuator shaft (Item 4) by pushing it from the outside into the waterway of

the shutoff. Remove and discard the old actuator shaft.

14. Repeat steps 7 and 8 to install the remaining new actuator shaft and o-ring.

15. With the shutoff handle (Item 16) in the open position insert valve ball so the slots on both sides of the

ball slide over the blades of the actuator shafts and push the ball back until it contacts the seat. The full
round valve ball can be installed in any orientation. The single cut-away ball must be installed with the
cut-away towards the inlet and at the bottom (opposite side from shutoff handle) of the shutoff. The
double cut-away ball must be installed either end first but with the cut-aways at the bottom (opposite
side from shutoff handle) of the shutoff.

16. Install a new adapter o-ring (Item 7) in the outlet end of the shutoff body (Item 8). (There is an

additional adapter o-ring for the inlet end of the shutoff body included in the in the kit. It is not
necessary to change this o-ring if the inlet adapter is not removed. To remove the inlet adapter follow
the same steps used to remove and install the outlet adapter, steps 1, 2, 3, 17, 18, & 19.)

17. Install a new o-ring (Item 6) and new seat (Item 5) into the outlet adapter (Item 18).

18. Before installing the outlet adapter (Item 18) please notice that there is a spot on the fine threads of the

outlet adapter where a drill has been used to remove the male threads. This spot drill is there so that the
set screw used to secure the adapter will not damage the male threads when tightened against the outlet
adapter. If the set screw were to be tightened against the male threads of the outlet adapter, the threads
would be damaged making future removal of the adapter difficult or impossible.

19. Install the outlet adapter (Item 18). Screw the outlet adapter in until the spot drill lines up with the set

screw hole in the shutoff body (Item 8). Apply #262 Loctite, install, and tighten set screw (Item17)
making sure set screw tightens against spot drill on outlet adapter.
