18. Using a jib crane or equivalent, gently lower the Top (14) onto the Body (4). Make
certain that the match up lines on the crown flanges of the Top (14) and Body (4) line up
as close as possible.
19. Retrieve the stud bolt Hex Nuts (32) from storage and lubricate the threads with a low-
viscous oil.
20. Install two Hex Nuts (32) on both "long" sides of the crown flange joint and tighten to
“snug” only.
21. Rotate the Slide Valve Shaft (5) to move the soft seat slide valve assembly from full
“open” to full “close” position several times to verify that it operates smoothly.
22. Rotate the Slide Valve Shaft (5) to move the soft seat slide valve assembly into its
“open” position.
23. Retrieve the Plate Carrier (8DM or 8DMC) from its safe storage.
24. Reinstall it into the Senior Top (14) by rotating the Upper Plate Carrier Shaft (7) to
“back-rack” the Plate Carrier (8DM or 8DMC) and then reversing the Shaft rotation to
lower the Plate Carrier (8DM or 8DMC) into the slot region of the Top (14).
25. Continue to lower the Plate Carrier (8DM or 8DMC) through the Slide Valve Seat (18) to
verify that it clears the soft seat slide valve assembly and engages the Lower Plate
Carrier Shaft (6).
26. Rotate the Lower Plate Carrier Shaft (6) until the Plate Carrier (8DM or 8DMC) rests
against the Plate Carrier Stop Pin (42).
27. Raise and lower the Plate Carrier (8DM or 8DMC) several times to verify smooth
operation. Movement of the Top (14) may be required to accomplish this task.
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)when
lowered and could possibly require the removal of the Top (14) to extract the Plate Carrier (8DM
or 8DMC) from the Body (4).
28. With the Plate Carrier (8DM or 8DMC) resting against the Plate Carrier Stop Pin (42),
rotate the Slide Valve Shaft (5) to move the soft seat slide valve assembly to its full
“close” position and full “open” position several times. This is to verify that it operates
smoothly over the Plate Carrier (8DM or 8DMC). For assemblies using the Plate Carrier
(8DMC), a slight pressure will be observed as the soft seat slide valve assembly moves
over the Plate Carrier (8DMC).
LIFTING HAZARD
The field technician should always use mechanical assistance when lifting the Top (14).
Failure to do so may result in serious injury.
