Senior Fittings 2"-8" for "API-14.3"
1.
Retrieve the Plate Carrier (8DM or 8DMC) from its safe storage.
2.
Reinstall it into the Senior Body (4) by first rotating the Lower Plate Carrier Shaft (6)
"backwards" to "back-rack" the Plate Carrier (8DM or 8DMC), ensuring proper gear
engagement, and then reversing the Shaft rotation to lower the Plate Carrier (8DM or
8DMC) into the slot region of the Body (4
),
until it rests against the Plate Carrier Stop
Pin (42).
Important
Mismatch of the Plate Carrier (8DM or 8DMC) racks and Shaft pinions will prevent the Plate
Carrier (8DM or 8DMC) from resting properly against the Slide Valve Carrier Stop Pin (17A).
3.
Retrieve the Soft Seat Spring-Loaded Slide Valve Carrier Guides (16-SS) from the parts
kit.
4.
Place the guides on the guide rails of the Soft Seat Slide Valve Carrier (17-SS) and install
this assembly onto the machined pads above the Shafts.
5.
Make certain that the racks of the Soft Seat Slide Valve Carrier (17-SS) engage the
pinions of the Slide Valve Shaft (5).
6.
With the Plate Carrier (8DM or 8DMC) resting against the Plate Carrier Stop Pin (42),
and while holding the slide valve assembly in place against the machined pads, rotate
the Slide Valve Shaft (5) to move the slide valve assembly to its full "close" and full "open"
position several times.
The Plate Carrier Spring Pin (8A), which is installed in the Plate Carrier (8DM or 8DMC),
should depress slightly as the Soft Seat Slide Valve Carrier (17
SS) moves over it. The
Soft Seat Slide Valve Carrier (17-SS) should not contact the Spring Pin body (if the
Spring Pin requires an adjustment, it can be raised or lowered by using a 3/8” or wider
flat blade screwdriver to depress the spring plunger, inserting the blade in the notches
outside of the plunger and rotating as needed).
7.
Rotate the Slide Valve Shaft (5) to move the slide valve assembly to its "open" position
and expose the Plate Carrier (8DM or 8DMC). By rotating the Lower Plate Carrier Shaft
(6), raise and lower the Plate Carrier (8DM or 8DMC) within the slot region of the Body
(4) to verify that the Plate Carrier (8DM or 8DMC) will clear the slide valve assembly.
If
a
dditional clearance is needed, file or grind the body cavity or Soft Seat Slide Valve
Carrier's (17-SS) rack. Store the Plate Carrier (8DM or 8DMC) in a safe place for reuse
later.
8.
Rotate the Slide Valve Shaft (5) to move the slide valve assembly until it partially covers
the slot within the Body (4).
Do not move the Soft Seat Slide Valve Assembly from this position,
. If the Soft Seat Slide
Valve Assembly is located too far in either direction, the Assembly might be damaged or it could
become dislodged and possibly cause damage to the Soft Seat Slide Valve Seat (18-SS).
