50 Ton Ram Instruction Manual
Place a rubber sheet or pad under the IX Master
plate. Move the directional control lever to the
“REVERSE” position. While holding the hose and
ferrule firmly against the stem shoulder, engage the
ram by depressing the button on the remote. The
internal expansion operation is complete when the
expansion plug is pulled completely through the
stem (see
Important! below). Release the button
on the remote. Visually inspect the coupling and
clean excess lubricant from the stem I.D.
Important! When the pressure gauge drops to zero, release the button on the remote.
Pull the assembly off of the plug and, at the same time, remove the adapter(s) from the IX Master Plate.

Note: If the gauge reads 10,000 PSI before expansion is complete, stop.
The ferrule or die used for that hose end may be incorrect.

* Assembly procedure for 2½" & 4" threaded male stems:
In order to prevent possible thread collapse on the 2½" & 4" male NPT stems (carbon steel) during installation,
it is recommended that a female threaded adapter be installed prior to installation. The adapter part number for
2½" is M011-384 and 4" is M011-385. Following is the procedure for installation:
1. Lubricate stem I.D. and small end of expansion plug.
2. Thread M011-384 or M011-385 onto threads of the male stem hand tight only!
3. Slide stem over pull rod thread adapter first.
4. Seat M011-384 or M011-385 into outer recess of the adapter.
5. Follow normal IX procedure.
6. When assembly is removed from the adapter, remove M011-384 or M011-385 and clean the stem I.D. of
excess lubricant.
Procedure changes for stainless steel food grade couplings
1. Step 3a. - Must use Crisco® for lubricant.
2. Step 3b. - Must use Crisco® for lubricant.
3. When IX plug is removed and cleaned of lubricant, the visible lines on the plug are deposits of stainless
steel. Remove the deposits with 200 - 400 grit wet / dry sandpaper. This is to be done after every pull.
4. Make sure the expansion plug to be used has “FD” in the part number (stamped on the large end of the
plug). If “FD” is not in the part number DO NOT USE IT!
