HB Coupling Expander Instructions
DESCRIPTION:
The HB Expander is a hand operated pull through type expander. It is used in a xed location
for small production runs or as a portable repair type expander.
The HB Expander will attach all sizes of Dixon Holedall Petroleum 570-H and 580-H series
(curb pump) couplings and sizes ¾" through 2" of 520-H series (fuel oil) couplings.
INSTALLATION:
The HB Expander is shipped assembled except for attaching the handles and threading the
drive screw through the drive screw nut. It can be held in a bench vice or secured to a bench.
Using either method, the expander should be positioned so that the handles overhang sufciently to give
freedom of movement when turning.
MAINTENANCE:
1. The Drive Screw No. 5 must be kept well lubricated with graphite grease.
2. Oil periodically where indicated on Body No. 1.
OPERATION:
To expand couplings sizes through 1":
1. Select the proper size reducer (if male coupling), reducer and close nipple (if female coupling).
Screw reducer onto Thrust Connector No. 3 by hand, then screw male coupling into reducer
by hand, or if a female coupling, screw onto close nipple until it stops on the washer seat.
2. Position Drive Screw No. 5 (use ½" wrench on ats to turn drive screw) so that the end with
the tapped hole is approximately ush with the front end (threaded end) of the coupling.
3. Select the proper size punch and screw it into Drive Screw No. 5 using a ½" wrench to tighten.
Hold Drive Screw No. 5 from turning and turn the handles clockwise until punch enters coupling
under slight pressure. (Lubricating punch is not necessary - Dixon Holedall Petroleum ttings
are pre-lubricated).
4. To assemble 520-H series (fuel oil):
Place proper size ferrule on the hose so that the end of the hose is ush with the turned
over portion of the ferrule (end of hose must be cut square). Keeping the ferrule stationary
to the hose, slide the assembly over the punch and onto the shank of the coupling until top
of ferrule is 1/8" from coupling face. Holding the hose in place, slide the ferrule ush against
the coupling face. This allows the turned over portion of the ferrule to be anchored properly
during the expansion process.

OPERATION (continued):
5. To assemble 570-H & 580-H series (curb pump):
Push hose over the punch and into the coupling until hose bottoms out. (The easiest way
to ensure proper insertion depth is to measure and mark the coupling shank depth on the
hose).
6. Turn handles clockwise until resistance to turning ceases - indicating expansion is complete.
7. After expansion has been completed, remove Thrust Connector No. 3 from expander.
Unscrew Thrust Connector and reducer as a unit from coupling. Replace Thrust Connector
in machine, then remove Punch. Machine is now ready for next expansion.
To expand couplings sizes 1¼" through 2":
1. Drive Screw No. 5 must be reversed. Remove Drive Screw from Nut No. 2, reverse Drive
Screw and reassemble with Nut No. 2.
2. Select proper size reducer or reducer nipple. Screw coupling onto reducer (or reducer nipple).
3. Advance Drive Screw No. 5 through coupling until keyed extension of Drive Screw projects
beyond coupling.
4. Slide expanding punch onto keyed extension of Drive Screw. Screw on Lock Nut No. 7.
Turn handles clockwise until punch enters coupling under slight pressure.
5. To assemble 520-H series (fuel oil):
a) Place proper size ferrule on the hose so that the end of the hose is ush with the turned
over portion of the ferrule (end of hose must be cut square). Keeping the ferrule stationary
to the hose, slide the assembly over the punch and onto the shank of the coupling until top
of ferrule is 1/8" from coupling face. Holding the hose in place, slide the ferrule ush against
the coupling face. This allows the turned over portion of the ferrule to be anchored properly
during the expansion process.
b) Turn handles clockwise until resistance to turning ceases - indicating expansion is complete.
6. After expansion has been completed, remove Thrust Connector from machine. Unscrew
Thrust Connector No. 3 and reducer as a unit from coupling. Replace Thrust Connector
in machine. Remove Punch, machine is now ready for next expansion.
CAUTION !!
After starting the expansion of a coupling, the handles must never be turned counter clockwise. The Thrust
Bearing is a single direction action and reverse operation of the machine will
damage the Drive Screw.
