DISASSEMBLY OF EXISTING
GEARMOTOR PARTS
1, Remove fan cover and mounting tabs.
2, Remove snap ring (if used) from fan
hub.
3. Remove fan by prying between motor
end shield and fan near hub, Fan is
held on shaft with a snap ring (refer to
Figure 5, No. 24).
ASSEMBLY OF BRAKE KIT
See Figure 4,
'"..,,--..,,-------..---, Do not operate
J!. CAUTION
I manual release or
energize brake coil before installation in
corder to preserve preaJignment of rotating
disc and for ease of installation.
Slide shaft extension (Ref. No. 25) onto
motor shaft. Shaft should bottom out in
shaft extension bore. Tighten all three
set screws securely (35 in. Ibs. torque).
One set screw to be centered on flat of
motor shaft.
2 Install fan (Ref. No. 21) on shaft
extension. Flat side of fan to face motor.
Make sure that the molded key in fan
bore is placed into groove of the shaft
extension. Locate axially so that the
molded lugs in bore of fan fit into
annular groove of shaft extension. (Fan
should be flush with large diameter
shoulder on shaft extension.)
3 Expand snap ring (Ref. No. 24) to clear
hub of fan and position snap ring
approx. 1/8" in from end offan.
4, Place fan cover (Ref, No. 22) over fan
and shaft extension with flat portion of
fan cover towards mounting feet of unit.
Align mounting holes. install and tighten
fan cover mounting
screws. (Use screws removed from
disassembled fan cover.)
5, Install splined hub (Ref. No.2) with
key (Ref. No. 26) on shaft extension.

6. Remove the three brake cover machine
screws (Ref. No.3) and cover (Ref. No.
4). Position brake assembly over hub,
engaging splined hub with rotating disc
(Ref. No. 11). Release lever (Ref. No.
1) should be positioned opposite flat
portion of fan cover.
NOTE: Be sure anti-backlash spring
(Ref. No, 5) does not rest in a splined hub
tooth space containing a set screw. Align
mounting holes and fasten brake securely
to fan cover with two 1/4" flat head screws
furnished.
7. Connect coil lead wires as shown in
Figure 3. Replace cover and cover
screws.

L,
1
Consult motor manufacturer if high cycling
rates are expected.
If brake torque rating is higher than motor
full load torque rating, use brake rating
rather than motor rating when selecting
other drive components.
IACAUTION I
1. Do not operate brake at higher than
nominal static torque capacity.
2. For applications with high inertia type
loads or rapid cycling, service factor of
brake must be increased depending on
application.
3. Observe proper safety precautions when
an application involves a holding or
overhauling load operation; keep
personnel away from load area.
4. Be sure power supply conforms to
electrical rating of brake.

Operation
CONNECTION OF COIL LEADS
DUAL VOLTAGE COIL
This brake is a spring set device with an
electromagnetic release. It contains a
rotating friction disc which is driven by a
hub mounted on the motor shaft. When
energized. the magnet compresses the
torque spring, removing the force pressing
the stationary disc and friction disc
together, and permits free rotation of the
shaft.
This brake is equipped with a manual
release. Manually release the brake by
pushing the release lever forward until

.A WARNING
:
i Disconnect ??wer
~ before servlcmg!
(Numbers in parentheses are reference
numbers illustrated in Figures 4 and 5.
Refer to these figures below and on page
4 for the following procedures.)
WEAR ADJUSTMENT
As friction disc wears, magnet gap "A"
(refer to Figure 4)increases. When gap "A"
reaches .150" maximum, adjust to 0.060"
0.070". To adjust: Hold pivot nut (6),
loosen lock nut (7), turn pivot nut (6)
clockwise until air gap "A" measures
0.080" at center of magnet. [NOTE: Air
gap should decrease slightly to measure
0.060"-0.070" when lock nut (7) is
tightened against the pivot nut (6).]
Hold pivot nut (6) and tighten lock nut (7)
against it. Operate brake several times to
see if 0.060"-0.070" air gap is maintained.
If not, readjust following same procedure
again. Any delay in adjusting air gap will
result in a loss of torque and/or coil burn
out.
nut (9) as described under Magnet
Assembly Replacement. Readjust magnet
air gap as described under Wear
Adjustment.
FRICTION DISC REPLACEMENT
MAGNET ASSEMBLY REPLACEMENT
When total wear on rotating friction disc
(11 ) reaches 1/16", replace disc as
follows: Remove the three cover machine
screws (3). cover (4), lock nuts (9).
magnet assembly (8). rubber washers
(10), hex nuts (12), torque springs (13),
armature (14), lock nut (7), pivot nut (6),
pressure arm (15) and stationary disc (16).
Install new rotating disc (11) making sure
anti-rattle spring (5) is installed in position
shown and does not rest in a hub tooth
space containing a set screw.
Reassemble all parts in reverse order.
Remove cover machine screws (3), cover
(4), lock nuts (9) and magnet assembly
(8). Replace magnet assembly. Be sure
rubber washers (10) are under magnet
bracket. Tighten lock nuts (9) to remove
end play between nut and magnet
bracket. Tighten with an additional 1/3 turn
(two flats on nut). Check air gap as
described under Wear Adjustment and
replace cover and cover screws.
NOTE: In reassembly tighten pivot nut (6)
so that it makes contact with pressure arm
(15). Locate hex nut (12) 17/32" from end
of stud as shown in Figure 4. Tighten lock
