Theory of Operation
The clutch consists of stators, a rotor, drive cylinder, coil, magnetic powder, and bearings which
support the drive cylinder and rotor in the stators. The magnetic powder occupies the space
between the drive cylinder and rotor, and functions as the adjustable bond or link between them.
It is the medium for the transmission of torque.
A current in the coil creates a magnetic field (flux) which passes through the stators, drive
cylinder, magnetic powder and rotor. The flux aligns the powder, forming links or bonds
between the rotor and drive cylinder. The strength of the bonding action (torque) is proportional
to the amount of current in the coil.

Installation
Prior to installation, check the rotation by hand and observe that it is smooth and free of binding
or scraping.
1. Mount the clutch to a base using four suitable bolts. The rotor shaft centerline must be
mounted within 30° of the horizontal plane.
2. The outer rotating member is the input, since heat dissipation is related to outer rotating
member speed.
3. When using couplings or belts, insure clutch is properly aligned. Flexible couplings must
be used for in-line installations.
Water Cooled Clutch
GENERAL: Coupling the output (rotor) to the load may be done using gears, sprocket and
chain, or pulley and belt systems. The rotary fitting mounted on the end of the shaft does not
allow direct coupling to the load. The clutch must be connected through the power transfer
device before the water fitting is attached.
To install a water cooled clutch install the water fitting as follows:
1. Install the washer on the threaded shaft and screw the water fitting into the clutch shaft.
2. Connect the input hose which is the end hose to your water source.
3. Connect the drain hose which is the inside hose (hose nearest clutch housing) to your
drain outlet.
To prevent internal condensation, control the input water with an electrically operated solenoid
valve. Insure that the input water flow is off when the clutch is off.
Electrical Connection
For 24 VDC Devices:
1. Connect the two wires in the clutch junction box to the 24 vdc power source.
For 90 VDC Devices:
1. Connect the 90 vdc power source to the terminals marked 1, 2.
2. Connect the protective bonding circuit to the terminal marked with the P.E. symbol

CURRENT RATINGS
Note: The clutch coil system has been changed from Class A to Class F. Refer to the
nameplate on your unit to determine which insulation class you have. If you have Class F
insulation, the nameplate will denote Class F. If you have Class A, there will be no notation on
the nameplate.

Maintenance
Due to its small number of moving components and its basic design, maintenance of the brake
is generally necessary only after extended service. When a problem appears in the system,
ensure that all couplings, belts, etc., and the control device are functioning properly. Use the
Troubleshooting guide below to determine the cause of the problem. The clutches can be
rebuilt with a repair kit which puts it into “as new” condition. A repair kit includes a new powder
charge and the appropriate bearings, seals and snap rings generally needed to rebuild the unit.
NOTE: When ordering parts not contained in the kit, provide the model number, serial number
and parts list item number.

Troubleshooting
PROBLEM
POSSIBLE CAUSE
ACTION
Load has slowed down due to
insufficient torque transmitted
between motor and load
Power supply voltage output low
Magnetic powder has deteriorated
or is partially lost
Replace or repair power supply
Overhaul clutch using repair kit
Load has stopped and clutch
rotor is not running with
proper voltage
Coil is open
Replace coil
Load operated intermittently
with proper voltage
Coil is intermittently open
Replace coil
Clutch is noisy and has some
vibration
Clutch bearings are worn
Overhaul clutch using repair kit
Disassembly
The following step-by-step instructions pertain to the Model C10 clutch. Due to the similarity of
clutches covered in this manual, the step-by-step instructions can be used as a guide in
disassembly of all other models. Areas of major difference are covered under notations in the
text. When disassembling the clutch refer to the figure while following the text.
1. Remove the junction box cover, nameplate, mounting brackets and retaining screws.
2. Remove the screws retaining the end bell on the drive cylinder.
3. Disassemble left stator and right stator by removing screws.
4. Remove coil.
NOTE: The clutch is now disassembled into loose parts plus the rotating group. The
following steps outline disassembly of the rotating group.
5. In the following step the powder will be released.
6. Remove screws and empty the powder.
C1 NOTE: The end bell in a C1 is retained in the drive cylinder by a press fit. Use a thin-
bladed object and carefully remove the end bell.
7. Remove snap ring and shims. Some clutches will not have a shim. If a shim is found, it
should be re-installed at the same place during assembly.
8. Use a bearing puller to remove bearing from rotor. Remove snap ring before pulling
bearing. Discard seal. (Some units, C100 and C50 have a snap ring behind the second
bearing which must be removed before the end bell.)
9. Remove bearings and snap rings from drive cylinder shaft in same way.

Assembly
Assembly of the clutch should be performed in a clean area. The clutch components must have
all old powder scraped or sanded from OD of rotor and ID of drive cylinder, then cleaned with
solvent and be totally free of any grease or oil. Discard all bearings and magnetic powder from
disassembled clutch.
1. With bearing seal (rubber side) facing shaft fins, use an arbor press and press bearing into
shaft. Press on inner race only. BEARINGS MUST BE HIGH TEMPERATURE (P/N
29L30A40).
2. Assemble snap ring onto shaft.
3. Install spacer.
4. Press bearing onto shaft with bearing seal facing away from fins. Press on inner race only.
5. Replace snap rings and shims.
6. With seal lip facing away from end bell fins, press seal into end bell until it bottoms.
7. Slide end bell with seal onto rotor shaft. Use a tube such as thin plastic to aid in sliding the
seal over the shaft shoulder.
8. Install snap ring if there is a groove next to seal surface.
9. With bearing seal (rubber portion) facing end bell fins, press bearing onto rotor shaft.
Press on inner race only.
10. Install snap ring and spacer.
11. Press bearing onto rotor shaft with bearing seal facing away from fins
12. Replace snap ring and shims.
13. Pour magnetic powder into drive cylinder.
14. Place rotor into drive cylinder.
C1 NOTE: End bell is a press fit into drive cylinder. Secure with retaining compound; do
not get any retaining compound in the powder.
NOTE: Drive cylinder and end bell are balanced as an assembly. The components are
marked and must be aligned during assembly.
15. Align balance marks on end bell with those on drive cylinder. Replace screws.
16. Assemble right stator over rotor end of rotating group and retain with screw into hole in
space.
17. Install coil and assemble left stator over drive end of rotating group.
18. Use a scribe to align holes of spacer with holes of left stator. Install screws and
lockwashers.
19. Attach mounting brackets and replace hardware, nameplate and junction box cover.
20. Turn the two shafts by hand in opposite directions while alternately elevating the shaft end
45° to distribute the powder evenly along the inside of the drive cylinder.
