8. Carefully remove the follower shaft and ball (key 2) from the outlet end of the valve body.
9. The bearings are not pressed in, so they can be removed with minimal force. Be careful not to damage the
machined surfaces of the bearing bore if prying is required.
10. For HD seal removal, follow the steps outlined under Removing HD Seal on page 7.
Assembly
1. Inspect all sealing surfaces to ensure they are in good condition and without scratches or wear.
2. Install the HD ball seal. See Installing the HD Seal on page 12, and follow steps 1 — 4. Then return to this procedure
and continue with the next steps.
3. Install the replacement bearings(key10)byhand.Thebearingflangedendshouldtouchthevalvebody.
4. Installing the Vee-Ball:
Lubrication will assist with break-in of the HD metal seals and with assembly. It is required that both the ball surface
and seal be lubricated with dry film lubricant or equivalent moly disulfide.
WARNING
The ball might be damaged if it is allowed to fall into the valve body. To avoid personal injury or damage to the sealing
surfaces, support the ball to prevent it from falling into or out of the valve body cavity.

from the outlet end.
When installing the ball (key 2) into the valve body assembly, firmly support the ball while installing the shafts in the
following steps.
5. Installing the follower shaft (key 9):
D For NPS 3x4 valves: The follower shaft (key 9) should already have been inserted into the ball ear before the ball was
put into the valve body. With the ball rotated open and not in contact with the HD seal, insert the follower shaft
(key 9) into the valve body bearing (key 10).
D For NPS 4x6 and larger valves: With the ball rotated open and not in contact with the HD seal, insert the follower
shaft (key 9) through the ball, and into the valve body bearing (key 10).
6. Align the hole in the follower shaft with the holes in the ball. Insert the small end of the groove pin (key 7) into the
hole in the ball and into the follower shaft. The pin will hold the parts in place while the drive shaft (key 6) is being
installed.
7. Installing the Drive Shaft:
CAUTION
The drive shaft must be used with the correct Vee-Ball. Refer to the tag (see figure 7) attached to the Vee-Ball and to the
drive shaft.
Failure to use the correct Vee-Ball/ shaft combination may result in the ball not being in the position indicated by the slash
mark on the end of the shaft. If the ball is not properly aligned with the slash mark, the valve will not function correctly and
seal damage may result.
