Clutch-Coupling Pin Drive Armatures
The illustration drawings, parts lists, and exploded
views for these units can be found on pages 30, 31 and
34 thru 37.
A. Aligning the Shafts
In order for the clutch-coupling unit to operate
properly, the mounting shafts of the motor and
reducer or other hardware must be aligned with respect
to each other before the unit is installed. The two shafts
should be con cen tric with each other within .004 T.I.R.,
and angular alignment should be within 1/2 degree.
(Figure 1)
1. Use a straight-edge to check if the shafts are
aligned with each other. For a more precise
indication of align ment, use a dial indicator.
2. Adjust the position of the motor, reducer, or
other hardware as required to achieve the correct align ment.
3. To be sure the shafts stay in alignment, drill
holes for tapered dowel pins through the
mounting bases of the motor, reducer, or other
hardware and into the mounting surfaces. This
procedure will ensure that, after the clutch-coupling has been installed, the shafts can easily
be placed in proper alignment again by lining
up the holes and secured by inserting the dow el pins.
B. Installing the Conduit Box
Install the conduit box on the field. Instructions for this
procedure are supplied with conduit box.
C. Mounting the Field-and-Rotor Assembly
Either the field-and-rotor assembly or the
armature-and-hub assembly can be installed first,
depending on the char ac ter is tics of each application.
The SFC-500 clutch-couplings are bearing-mounted
units. The SFC-650 units are either bearing-mounted or
flange-mounted.
Figure 1
Bearing Mounted Units
In bearing-mounted units, the field and rotor are
shipped as an assembly. Step 1 applies only to the
SFC-650 units. Steps 2-5 apply to both the SFC-650
and SFC-500.
1. The SFC-650 field and rotor assemblies are
mounted on the shaft with a taperlock bushing.
Insert the bush ing into the ta pered bore, lining
up the clearance holes in the bushing flange
with the tapered holes in the rotor hub.
2. Insert a key into the keyway in the bore of the
rotor and slide the assembly onto the shaft.
3. If the armature has been secured to the shaft
first, then adjust the rotor’s position to allow
ap prox i mate ly 1/32-inch between the two faces.
(Figure 11)
4. Secure the assembly on the shaft by alternately
tight en ing the two screws.
5. A tab or torque arm is provided to prevent the
field from rotating with the shaft. Insert either a
pin in the U-slot or a fork around the torque arm
to prevent this rotation. Under no circumstances, however, should the field be so tightly
restrained that is preloads the bearing. For more
information on torque tabs, see page 18.

Flange-Mounted Units
Field
Pilot Diameter
Mounting Surface
The fields and rotors are shipped separately for
flange mounted units. On some applications it will be
nec es sary to mount the rotor first, and then bring the
field into position. In other instances the field will be
mounted first, and then the rotor (mounted on a shaft)
will be inserted into place.
In either case, the rotor and field must be
positioned in accordance with the overall axial
dimension from the face of the rotor to the back of
the field flange as shown on the illustration drawings
(dimension “L,” page 34). Hold ing this dimension will
assure the proper axial clearance between the field
and the rotor.
1. Care must be taken in selecting the location
for mount ing the field assembly. Pilot diameters are ma chined on the field mounting flange
to aid in holding the field in the proper position.
2. An appropriate pilot diameter must be
provided on the mounting surface as well.
(Figure 2)
3. The field assembly is then fastened in place
with capscrews and lockwashers. (Figure 3)
Figure 4
4. Once the unit is in place, it must be square
and con cen tric with the shaft in accordance
with the tol er anc es listed on the drawings.
(Figure 4)
Figure 2
5. The rotor is mounted on the shaft with a
taperlock bushing. Insert the bushing
into the tapered bore.
6. Loosely assemble the two locking screws
between the bushing and the rotor.
7. Insert the key into the shaft keyway, and slide
the rotor assembly over the key and on to the
shaft.
8. Adjust the rotor’s position to achieve the overall axial dimension “L” (page 34) when the
bushing is se cured.
9. Secure the assembly in this position by
alternately tightening the two locking screws.

Assemble the armature to the armature hub with the
autogap mounting accessory. The hub is reversible.
The side on which the armature is mounted will
depend on the direction in which the taperlock bushing must enter.
The autogap assembly is a double spring device
which allows for automatic armature clearance and
adjustment for wear. The smaller or conical spring
pushes the ar ma ture from the rotor face, leaving a
gap of about 1/32 inch, while the straight spring automatically follows up for wear. This combination maintains maximum performance ef fi cien cy throughout the
life of the unit.
The assembly procedure for the autogap accessory
is as follows. (Figure 5)
Step 1 Place the straight springs over the armature
bosses on the back side of the armature.
(Figure 6)
Step 2 Place the
armature hub over the
straight springs.
Figure 6
Figure 7
The straight springs must fit into the grooves
in the
armature hub. (Figure 7)
Step 3 Compress the conical springs against the
retainer rings by sliding the detent springs
toward the head of the pins.
(All pins) (Figure 8)
Step 4 Insert the assembled drive pins through the
armature hub and straight springs and into
the threaded armature boss es. Apply grade

fit, the pins may seem to bind.
Note: Alternately tighten each drive pin a
few turns at a time.
1. Place the bushing into the hub and insert the
key. The key is a side-to-side fit and should
not contact the top of the keyway.
2. Insert the locking setscrews loosely into the
bushing and slide the assembly onto the
shaft.
3. If the field-and-rotor assembly has been
secured to the shaft first, then adjust the
armature’s position to allow approxi-
mately 1/32-inch between the two fac es.
Once this 1/32-inch gap has been set, it will
be au to mat i cal ly maintained throughout the
life of the unit. (Figure 11)
4. Secure the armature’s position on the shaft by
al ter nate ly tightening each setscrew. During
the tight en ing process the bushing should
be tapped lightly to make sure it seats-in
properly.
Step 6 Compress the retainers against the armature
hub and check to see that the armature hub
is held tightly to the armature bosses. Note:
This position must not be dis turbed during
completion of assembly. (Figure 10)
E. Mounting the Armature Assembly
The armature assembly is mounted on the shaft with a
taperlock bushing. All parts must be clean and free

The SFC-500 clutch-couplings are bearing-mounted
units. Either the field-and-rotor assembly or the
ar ma ture-and-hub assembly can be installed first,
depending on the characteristics of each application.
A. Aligning the shafts
Before the clutch coupling can be installed, the
mount ing shafts of the motor and reducer or other
hardware must be aligned to each other. Follow the
instructions provided for the pin drive units on page 3.
B. Installing the Conduit Box
Installed the conduit box on the field assembly.
In struc tions for this procedure can be found on are
supplied with conduit box.
C. Mounting the Field-and-Rotor
Assembly
The clutch-coupling units contain spline drive armatures and hubs. The armatures are shipped with a
built-in autogap spring accessory. This device automatically maintains a gap of about 1/32'' between the
armature and magnet faces for the life of the unit.
(Figure 3)
These units are shipped with the armature and
autogap already assembled. Follow these instructions
to as sem ble the splined armature assembly and hub:
Step 1 Place the splined hub on a flat surface. The
extended portion of the hub, where the set
screw holes are lo cat ed, should be down.
Step 2 Check the detent ring in the armature
assembly to make sure it is centered evenly
around the spline. This ring moves freely,
but it should be centered for easier as sem bly of the hub.
Step 3 Holding the armature with the segmented
side up, press the armature onto the splined
hub. This is most easily done by applying
firm back-and-forth pressure. (Figure 2)
Step 4 Push the assembly up against the retainer
ring.
1. Insert a key into the keyway in the bore of the
rotor, and slide the assembly onto the shaft.
2. If the armature has been secured to the shaft
first, then adjust the rotor’s position to allow
ap prox i mate ly 1/32-inch between the two
faces. (Figure 3)
Figure 3
3. Secure the assembly on the shaft by
alternately tight en ing the two setscrews.
4. A tab or torque arm is provided to prevent the
field from rotating with the shaft. Insert either
a pin in the U-slot or a fork around the torque
arm to prevent this rotation. Under no
circumstances, however, should the field be
so tightly restrained that it preloads the bearing. For more information on torque tabs, see
page 18.

E. Mounting the Armature-Hub Assembly
1. Insert a key in the keyway of the hub and
slide the armature-hub assembly on to the
shaft.
2. If the field-and-rotor assembly has been
se cured to the shaft first, then adjust the
armature’s position to allow a 1/32-
inch gap between the two faces. (Fig ure 3)
3. Secure the armature-hub assembly in this
po si tion by tightening the two setscrews in
the hub.
4. Check the assembly by pressing the armature
into contact with the rotor face and then
releasing it. The armature should spring back
about 1/32''. This gap will be automatically
maintained for the life of the unit.

A. Aligning the Shafts
In order for the clutch-coupling unit to operate
properly, the mounting shafts of the motor and the
reducer or oth er hardware must be aligned with
respect to each other before the unit is installed.
The two shafts should be con cen tric with each
other within 004 T.I.R., and angular align ment
should be within 1/2 degree.
1. Use a straight edge to check if the shafts
are aligned with each other. For a more precise indication of align ment, use a dial indicator.
2. Adjust the position of the motor, reducer, or
other hardware as required to achieve the
correct align ment.
3. To be sure the shafts stay in alignment, drill
holes for tapered dowel pins through the
mounting bases of the motor, reducer, or
other hardware and into the mounting
surfaces. This procedure will ensure that,
after the clutch-coupling has been installed,
the shafts can easily be placed in proper
alignment again by lining up the holes and
secured by inserting the dow el pins.
The brake half of the clutch/brake unit is usually
installed first; however, in some cases it may be necessary to start with the clutch portion of the unit to
assure a proper as sem bly when complete.
The brake magnet is mounted to a stationary machine
member by a flange. Extreme care must be taken in
se lect ing the location for the mounting of the magnet.
Prop er positioning is very important for the unit to
function cor rect ly.
1. A pilot diameter on the mounting surface is
essential to hold the magnet within the
required tolerances. (Figure 2)

F. Mounting the Field-and-Rotor Assembly
1. Insert a key into the keyway in the bore of the
rotor, and slide the assembly onto the shaft.
2. Adjust the rotor’s position on the shaft to
Figure 15
allow ap prox i mate ly 1/32'' between the faces
of the rotor and armature. Secure the rotor in
this position by al ter nate ly tightening the two
locking screws. Once this 1/32'' gap is set, it
will be automatically maintained throughout
the life of the unit. (Figure 15)
3. Secure the assembly on the shaft by
alternately tight en ing the two setscrews.
4. A tab or torque arm is provided to prevent
the field from rotating with the shaft. Insert
either a pin in the U-slot or a fork around the
torque arm to prevent this rotation. Under no
circumstances, however should the
field be so tightly restrained that it preloads
the bearing. (For more information on torque
tabs, see page 18.)

Torque Tabs
Clutches
Many Warner Electric clutch assemblies have a bearing
mounted stationary field. By design the bearing main tains its proper position between the field and rotor
mak ing it easy for the customer to mount the field-rotor
as sem bly. However, the bearing has a slight drag which
tends to make the field rotate with the rotor if not re strained. And, since the field has lead wires attached, it
must be restrained to prevent rotation and pulling of
these wires. To counteract this rotational force, the field
has a “torque tab” to which the customer must attach
an ap pro pri ate anti-rotational restraint.
A few hints regarding proper torque tab restraints are in
Figure 1
Rigid Member
order. First and foremost, it is important to recognize that
the force to be overcome is very small and the tab
should not be restrained in any manner which will preload the bearing. For example, if the clutch is mounted
with the back of the field adjacent to a rigid machine
member the customer should not attach a capscrew
tightly between the tab and the machine member. This
may pull the tab back against the rigid member as shown
in Figure 1 and preload the bearing. The recommended
methods are il lus trat ed in Figures 2, 3, and 4. The
method selected is primarily a matter of customer preference or con ve nience.

Step 1 Fasten bracket (1) to the clutch or brake
with one No. 10-32 hex. washer head screw
and washer (2). The square projection on
the clutch or brake between the terminals is
to be assembled into the square hole in
the bracket. The bracket flange is
installed toward the back of the unit.
(See Figure 1)
Figure 1
Step 2 Assemble a 1/2" flexible conduit fitting into
the desired end of the conduit box (3). If the
grounding nut on this conduit fitting is
tightened after the conduit box is in stalled on the magnet or field, avoid using
excessive tap ping force, which could damage the mounting. (Step 6)
Step 3 Mount conduit box (3) to the bracket (1).
The con duit box flange must be toward the
back of the clutch or brake. Secure the box
with two No.10-32 hex. washer head screws
(4). (See Figure 2)
Figure 3
Step 5 Push two terminal spacers (7) through the
grom mets with the spacer flanged ends
inside the conduit box. (See Figure 3)
Step 6 Connect electric supply cable to the fitting
installed on the conduit box. Use D.C.
supply only.
Rigid conduit must not be con nect ed
directly to the box. A minimum of 12" of flexible
cable must be used. It is recommended that
flexible "UL" listed liquid-tight, me tal lic or
non-metallic conduit, meet ing local codes, be used
with appropriate fit tings. Flexible cable is required
to prevent side loading of bearing on bear ing
mounted clutches and brakes and possible
de for ma tion of the conduit box or com po nents
during assembly.
Step 7 Press protective plug (5) into the unused
conduit hole in the box.
Step 8 Slide one rubber cap (8) onto each of the
two supply conductors, small end first.
Figure 2
Step 4 Snap the two rubber grommets (6) into two
square holes in the bottom of the conduit
box. The grom met crowns should be in the
box and the rubber flanges should be on
both sides of the metal floor. (See Figure 3)

Connect the two supply con duc tors (with
rubber caps) to the magnet or field ter mi nals
using two No. 6 or No. 8 screws (11). Use
wire re tain ing ring terminals supplied with
the clutch or brake terminal accessory. The
stripped wires may be wrapped around the
screw between the wire terminal ring and
the screw head or other ring type terminals
such as "AMP" may be used. The screws
are then assembled through the terminal
spacers (7) and threaded into the clutch or
brake terminals.

Burnishing and Maintenance
Burnishing
Intimate metal to metal contact is essential between
the armature and the metal rings (poles) of the magnet
or rotor. Warner Electric clutches and brakes leave the
fac to ry with the friction material slightly undercut
to assure good initial contact.
Foreign Materials: If units are used on machinery
where fine, abrasive dust, chips or grit are dispelled
into the at mo sphere, shielding of the brake or clutch
may be nec es sary if maximum life is to be obtained.
Where units are used near gear boxes or
transmissions requiring frequent lubrication, means
should be pro vid ed to protect the friction surfaces
from oil and grease to pre vent serious loss of torque.
Normally, the desired wearing-in process occurs
nat u ral ly as the surfaces slip upon engagement. The
time for wear-in, which is necessary to obtain the
ultimate torque of the unit, will vary depending on
speed, load and cycle duty.
If maximum torque is required immediately after
in stal la tion, the unit should be burnished by
slipping the friction surfaces together at reduced
voltage. It is rec om mend ed that the burnishing be
done right on the application, if at all possible.
Burnishing at high speed will result in a smoother
wear-in pattern and reduce the time for burnishing.
The volt age should be set at approximately 30% or
40% of the rated value.
The unit should be cycled on and off to allow
sufficient time between slip cycles to prevent
overheating.
When a Warner Electric brake or clutch is properly
as sem bled and installed, no further servicing,
lubrication, or maintenance should be required
throughout the life of the unit.
Maintenance
Wear Pattern: Wear grooves appear on the
armature and magnet surfaces. This is a normal
wear condition, and does not impair functioning of the
unit. Normally, the magnet and armature, as a mating
pair, will wear at the same rate. It is the usual
recommendation that both components be replaced
at the same time.
Remachining the face of a worn armature is not
rec om mend ed. If a replacement armature is to be
used with a used magnet, it is necessary to
remachine the worn magnet face. In refacing a
magnet: (1) machine only enough material to clean up
the complete face of the magnet; (2) hold the face
within .005'' of parallel with the mounting plate; and
(3) undercut the molded facing material .002''.004'' below the metal poles.
Heat: Excessive heat and high operating
temperatures are causes of rapid wear. Units
therefore, should be ven ti lat ed as efficiently as
possible, especially if the ap pli ca tion requires fast,
repetitive cycle operation.
Oil and grease accidently reaching the friction
surfaces may be removed by wiping with a rag
dampened with a suitable cleaner, which leaves no
residue. In performing this operation, do not drench
the friction material.
If the friction materials have been saturated with oil
or grease, no amount of cleaning will be completely
ef fec tive. Once such a unit has been placed back in
service, heat will cause the oil to boil to the surface,
resulting in further torque loss.
Torque Loss: If a brake or clutch slips or loses torque
completely, the initial check should be the input
voltage to the field as follows:
90-Volt Series: Connect a DC voltmeter with a range
of 0-100 or more directly across the magnet or field
terminals. With the power on and the potentiometer turned up, a normal reading is 90 volts, although
85 to 95 is satisfactory. The reading should drop as
the potentiometer control is ad just ed
counterclockwise.
24-Volt Series: Use a DC voltmeter with a range of
0-30 volts or more. A normal reading is approximately
22-26 volts.
6-Volt Series: Use a DC voltmeter of approximately
0-15 volt range. A normal reading is from 5.5 to 6.5
volts.
The above checks normally are sufficient. Further
checks may be made as follows: a low range
ammeter, when connected in series with one magnet
lead, will normally in di cate approximately .40 amperes
for the 90 volt units, 1.0 ampere for the 24 volt, and
3.5 amperes for the 6 volt series. These readings are
with the power on and the potentiometer control in
the maximum position.
Ohmmeter checks should be made with the power off
and the circuit open (to be certain, disconnect one
lead to the magnet). Average resistance for the 90 volt
series is 220 ohms; for the 24 volt, 20 ohms; and for
the 6 volt series, 1.5 ohms. A very high or infinite
resistance read ing would indicate an open coil.
If the above checks indicate that the proper voltage
and current is being supplied to the magnet,
mechanical parts should be checked to assure that
they are in good op er at ing condition and properly
installed.

Warranty
Warner Electric LLC warrants that it will repair or replace (whichever it deems advisable) any
product manufactured and sold by it which proves to be defective in material or workmanship
within a period of one (1) year from the date of original purchase for consumer, commercial or
industrial use.
This warranty extends only to the original purchaser and is not transferable or assignable without
Warner Electric LLC’s prior consent.
Warranty service can be obtained in the U.S.A. by returning any defective product, transportation
charges prepaid, to the appropriate Warner Electric LLC factory. Additional warranty information
may be obtained by writing the Customer Satisfaction Department, Warner Electric LLC, 449
Gardner Street, South Beloit, Illinois 61080, or by calling 815-389-3771.
A purchase receipt or other proof of original purchase will be required before warranty service is
rendered. If found defective under the terms of this warranty, repair or replacement will be made,
without charge, together with a refund for transportation costs. If found not to be defective, you
will be notified and, with your consent, the item will be repaired or replaced and returned to you
at your expense.
This warranty covers normal use and does not cover damage or defect which results from
alteration, accident, neglect, or improper installation, operation, or maintenance.
Some states do not allow limitation on how long an implied warranty lasts, so the above limitation
may not apply to you.
Warner Electric LLC’s obligation under this warranty is limited to the repair or replacement of the
defective product and in no event shall Warner Electric LLC be liable for consequential, indirect,
or incidental damages of any kind incurred by reason of the manufacture, sale or use of any
defective product. Warner Electric LLC neither assumes nor authorizes any other person to give
any other warranty or to assume any other obligation or liability on its behalf.
WITH RESPECT TO CONSUMER USE OF THE PRODUCT, ANY IMPLIED WARRANTIES WHICH
THE CONSUMER MAY HAVE ARE LIMITED IN DURATION TO ONE YEAR FROM THE DATE OF
ORIGINAL CONSUMER PURCHASE. WITH RESPECT TO COMMERCIAL AND INDUSTRIAL
USES OF THE PRODUCT, THE FOREGOING WARRANTY IS IN LIEU OF AND EXCLUDES ALL
OTHER WARRANTIES, WHETHER EXPRESSED OR IMPLIED BY OPERATION OF LAW OR
OTHERWISE, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so
the above limitation or exclusion may not apply to you. This warranty gives you specific legal
rights and you may also have other rights which vary from state to state.
