6. Insert the piston, hex end trailing, into the bore of the Housing, and use socket to thread and tighten the piston onto the piston shaft.
7. Install the End Plug Seal in the groove on the hub of the End Cap.
8. Using the End Plug Wrench, thread the assembled End Cap, o-ring end leading, into the piston end of the Housing and tighten it.
9. Wrap the threads of the Swivel Sets with Teflon tape and thread the swivel with the male hose Coupler into the center of the End Cap.
Thread the Swivel with the female Coupler into the hole in the Housing directly above the End Cap.
3.2.4 Step for Assembly of the PXD-2, PXD-4 and PXD-8 Cylinder
3.2.4.1 Assemblies
1. Hold the link retaining pin lug in copper-covered vise jaws with the Housing horizontal.
2. Before inserting Rod Seal in the Housing, apply a coat of o-ring lubricant to the Seal and install it, lip end trailing, in the recess at
the bottom of the piston bore.
3. Insert the piston rod, notched end leading, into the Rod Seal and the small central opening from the piston end of the Housing.
The notch in the leading end of the shaft should be toward the Ball Plunger.
4. Push the Piston Rod inward until the hole for the Slider Pin aligns with the holes in the walls of the Housing.
5. Position one Slider on each side of the piston shaft and insert the Slider Pin through the hole in the Housing into both Sliders and
the piston shaft. The fit between the Pin and Sliders is an interference fit. Use a brass hammer and drift to set the Slider Pin
below the outer edge of both Sliders or deep enough to prevent the shaft ends from dragging on the Housing walls.
6. Install the End Plug Seal in the groove of the End Cap.
7. Insert the assembled End Cap into the Housing with the O-ring end leading and the threaded inlet hole upward. By using end cap
wrench tighten the end cap into the Cylinder.
In the following step, an excessive amount of grease will prevent proper tooth engagement between the Ratchet
and the Drive Segment causing the tool to malfunction.
In the following step, DO NOT use thread-locking compound on the screw threads.
8. Wrap the threads of the Swivel Sets with Teflon tape and thread the swivel with the male hose Coupler into the threaded hole
in the End Cap.
9. Apply some Synthetic Grease to the notch in the Piston Rod and the face of the Sliders.
3.2.5 Step for Assembly of the Tool
1. With the Cylinder Assembly in one hand and the Ratchet Link in the other, hook the notch on the shaft of the Piston Rod onto the
Drive Pin and bring the two assemblies together.
2. Insert the Link Pin into the hole in the Side Plate until the Ball Plunger snaps into the annular groove around the center of the
Link Pin.
