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 pack ing removal tools “clamshells”
(45052-1). Each set of clamshells consists of two pieces of metal bent in a U-shape.
2. Remove the black plastic plugs 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 and hex nut 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 elbow 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 from the pump by removing the hex cap screw which

the hex screw. Use one wrench to hold the lock nut in position while using the other
wrench to remove the hex screw.

sure you have a second air hose connected to the elbow on the shift block assembly.

pump. Serious injury or amputations may occur.

shut off the air.

WARNING: For your protection, always disconnect the air when instructed to do so.

clamshells between the piston rod and the center section. Center the tops under the hex
screw on either side of the piston rod.
