SECTION 4.0: GENERAL ASSEMBLY
This section is provided to a general overview for all the service needs of the HCR-PA-
11X10 line of pumps. An exploded view with Bill of Materials of all parts is included at
the back of this manual.
The general assembly of the HCR-PA-11X10 line of pumps consists of three major sub-
assemblies: AIR CAP, AIR BODY, and HYDRAULIC BODY. It is most efficient if each of
these three components is entirely sub-assembled prior to final assembly.
A.
MOUNTING THE RATIO PLATE TO THE HYDRAULIC BODY
Make sure that all components are clean and dry. Spread a thin film of
waterproof grease on the rod, hydraulic piston and bore. Place static seals (O-
rings) in the appropriate counterbores in the Hydraulic Body.
While holding the Ratio Plate sub-assembly by the air-end piston, align the
actuator to its counterbore and gently rock the hydraulic piston into the bore.
Slide the Ratio plate down the shaft until contact is made with the Body. Next,
install the four mounting bolts (1/4-20 x 1”) and lock-washers into the center
pattern and snug to just compress the lockwashers. If there are two more bolt
holes along the bottom edge, install these bolts now, without lock-washers, and
snug.
Lastly, tighten all bolts in small increments using a cross-type pattern to a final
torque of approx. 15 ft/lb.
B.
MOUNTING THE AIR BODY TO THE RATIO PLATE
Slip one air body gasket over the air piston and align to the edges with the
hydraulic body. Apply a thin film of waterproof grease to the bore of the Air Body
and lay atop the piston with chamfered bore edge down. Holding the Air Body
and piston with both hands, “squeeze” the body over the air piston seal and
wiggle down until contact is made with the body gasket.
Make sure that the serialized face of the Air Body is facing up. On later models,
body pins assure proper alignment. At this point, tie down the Air Body through
the Ratio Plate to the Hydraulic Body with the four mounting bolts (5/16-18 x 1
¾'') and lock washers. Snug the bolts until the lock-washers are compressed,
NOT torqued.
