25 Ton Ram Instruction Manual Internal Expansion of H-520 Couplings
Before you begin, make sure the Ram is fully retracted.
Install the Holedall Petroleum Thrust Plate Adapter
(25ROSTPA) to the end of the 25IXATTACH with set screws.
Select the proper Pull Rod.
For 5/8” and 3/4” use 25ROSTROD screwed together
with 25ROSTADP.
For 1” thru 1-1/2” use 25RODSMALL.
For 2” thru 4” use 25RODLARGE.
Screw the short threaded end of the rod into the face plate of
the 25IXATTACH.
Note: Picture shows 25RODLARGE.
Select the corresponding Thrust Plate for the size fitting that
you are installing. Assuring that the recess is facing outward
towards the operator, slide the Thrust Plate over the Pull Rod
until it reaches the 25ROSTPA. Align the holes in the Thrust
Plate over the pins. Tighten the wing nut to lock it in place.

Slide the stem over the Pull Rod and into the recess of the
Thrust Plate with the connection side of the stem facing the
ram. For male stems, insert the hex into the recess of the
Thrust Plate. For female stems, insert the first hex into the
Thrust Plate so that it goes all the way through, so that the
second hex will fit into the recess of the Thrust Plate.
Note: There is no need to lubricate the plug or stem. The
stems are pre-lubricated at the factory.
Screw (or slide) the IX plug, small end first, onto the Pull Rod
and into the shank of the stem. For 2” and above screw the
retaining nut on until it contacts the plug. Move the stem
slightly to allow for slack and hand tighten the plug or nut
until it is snug.
Hint: When doing more than 1 hose assembly of the same ID
size take the time to screw the Pull Rod further into the face
plate of the 25IXATTACH. This will allow for a shorter
cycle time.
