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 (8DM or
8DMC) stop pin.
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. Place the guides along the guide rails of the Soft Seat Slide Valve Carrier (17-SS) and
place these onto the machined pads above the Shafts located inside the slide valve
cavity of the Body (4). Make certain that the racks of the Soft Seat Slide Valve Carrier
(17-SS) engage the pinions of the Slide Valve Shaft (5).
4. Verify that the soft seat slide valve assembly has sufficient clearance to move freely over
the Plate Carrier (8DM or 8DMC). Material may need to be added or removed from the
Plate Carrier Positioner (17B) portion of the Soft Seat Slide Valve Carrier (17-SS) to
provide this clearance.
5. Place a depth indicator inside the Senior’s bore with its anvil against the Plate Carrier
(8DM or 8DMC).
6. While holding the soft seat slide valve assembly in place against the machined pads,
rotate the Lower Plate Carrier Shaft (6) to raise the Plate Carrier from its bottom rest
until it strikes against the Plate Carrier Positioner (17B) portion of the Slide Valve Carrier
(17).
The full indicated movement of the Plate Carrier (8DM or 8DMC) must be within the
values listed in
Table 5-5 . If adjustments are needed, the Plate Carrier Positioner (17B)
portion of the Soft Seat Slide Valve Carrier (17-SS) can be modified by grinding to
remove material or by welding with 316SS weld-rod to add material.
7. Rotate the Slide Valve Shaft (5) position and expose the Plate Carrier (8DM or 8DMC).
8. Remove the Plate Carrier (8DM or 8DMC) from the Body (4) by rotating the Lower Plate
Carrier Shaft (6). Store the Plate Carrier (8DM or 8DMC) in a safe place for reuse later.
9. Rotate the Slide Valve Shaft (5) to move the soft seat 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, Step 9 . 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).
