Remove Packing Set:
1. Place the pump in a vise by clamping onto the bottom slave arm. Be sure the
opening at the bottom of the center section is clear of the vise.
NOTE: To remove packing set you will use one set of the packing removal tools
(“clamshells”) (45051-1). Each set of clamshells consists of two pieces of metal bent
in a U-shape.
2. Remove the black plastic plugs (15515) on the side of the pump body.
3. Be sure the pump is set to mid-stroke.
NOTE: You should be able to access the hex screw (F-HB-04C-24) and hex nut (F-LN-04C)
through the holes in the pump head. If the pump is not at mid-stroke, connect and slowly
increase air to the pump until the pump is at mid-stroke. Be sure you have a second air
hose connected to the tee (MPM-2584) on the shift block assembly (VPRO-2000). Then
disconnect the air.
WARNING: Always disconnect the air when instructed to do so to prevent injuring
yourself and damaging the equipment.
4. Remove the upper slave arm (VPRO-1001 or 85717-1) from the pump by removing
the hex cap screw (F-HB-04C-24) which secures the slave arm to the pump ’s center
section. Use two socket wrenches to remove the hex screw. Use one wrench to
hold the lock nut (F-LN-04C) in position while using the other wrench to remove the
hex screw.
5. Move the pump to the top of the stroke by hand or reconnect the air to the pump. Be
sure you have a second air hose connected to the tee on the shift block assembly.
DANGER: Never insert fingers or tools into the pump cavity when air is connected to
the pump. Serious injury or amputations may occur.
6. Slowly increase the air pressure until the pump reaches the top of the stroke, and
then shut off the air.
7. Disconnect the air.
WARNING: For your protection, always disconnect the air when instructed to do so.
8. Insert the clamshells (45051-1) around the piston rod (85810-1). Insert the bottoms
of the clamshells between the piston rod and the center section. Center the tops
under the hex screw (F-HB-04C-24) on either side of the piston rod.
9. Reconnect the air to the pump.
DANGER: Never insert fingers or tools into the pump cavity when air is connected to
the pump. Serious injury or amputation may occur.
10. Slowly increase the air pressure until the hole for the hex screw (F-HB-04C-24)
appears then shut off the air.
