DE-STA-CO Output Overload Clutches Type F, FC, S, C, D, FC-SD, C-SD - Manual (Page 7)

6. Place BODY with the PLUNGERS face
down on a solid surface.
7. Remove DETECTOR MOUNTING
screws which will release the PLUNGER
assemblies.
Warning: The plunger assemblies are
spring loaded and under tension. Bodily
injury could result if the plunger assemblies
are not retained against a solid surface.
WARNING
High humidity, contaminants or wash down applica-
tions may cause rust within the clutch resulting in
operational failure. Lubricate every six months or
more frequently as the applications require.
7
Warning: Do not remove the detector
mounting screws as they must retain the
plunger assembly.
6. Install the assembled clutch on the output
shaft or flange of the INDEX DRIVE.
7. Prepare the DIAL, SPROCKET or DRIVEN
MEMBER with a center hole and mounting
holes to mate with the tapped holes in the
DRIVE PLATE. (Refer to CAMCO assembly
drawings.)
8. Install DIAL or DRIVEN MEMBER and
check if it is free to rotate.
9. Tighten DIAL mounting screws. Disengage
clutch and test for clearance between the
DRIVE PLATE and BODY (approximately
.002"). The center hole of the DIAL must
also clear the FLANGE PLATE.
WARNING: Dial mounting screws must not
protrude from the drive plate as
they may lock against the adjacent
surface making the clutch inoperative.
10. Remove the flange plate and
dial-drive plate assembly.
Caution: Do not loosen the dial
screws.
11. Using the DRIVE PLATE as a "Jig,"
drill and ream the DIAL dowel holes.
Deburr all holes.
12. Install dowel pins through the DIAL
into the DRIVE PLATE.
Warning: Dowel pins must not protrude
from the drive plate as they may lock
against the adjacent surface, making the
clutch inoperative.
13. Reassemble the FLANGE PLATE and DIAL-
DRIVE PLATE assembly to the clutch
BODY.
14. Test for proper torque setting.
Note: For added reliability and/or high
speed operation, a bronze bushing may be
inserted between the DIAL PLATE and the
FLANGE PLATE. Special bronze flange
plates are also available from CAMCO.
DISASSEMBLY INSTRUCTIONS
(Types F and S)
1. Remove DIAL mounting screws.
2. Remove DIAL or other driven member by
tapping under the DIAL to overcome dowel
pin friction.
3. Type S Clutch: Remove output shaft clamp
screws.
3A. Type F Clutch: Remove mounting screws.
4. Remove the clutch from the index drive.
5. Type S Clutch: Remove mounting screws.
CAMCO CLUTCHES are precision assemblies and
should not be modified. Modification of the clutch
will VOID THE CAMCO WARRANTY.

ASSEMBLY INSTRUCTIONS
See Fig. 4 and Fig. 5
Important: To obtain maximum accuracy in
positioning the DIAL PLATE, the INDEX DRIVE
"CAM SHAFT" must be in the EXACT CENTER
OF DWELL position. See CAMCO drawing
applicable to the Index Drive Model.
1. Lubricate output shaft and dial mounting
surface of the INDEX DRIVE with
Mobilgrease 77 or equivalent.
2. Prepare the DIAL with center hole as
required. (Refer to CAMCO assembly
drawings.)
3. Place the DIAL on the output mounting
flange of the INDEX DRIVE and check if it is
free to rotate.
Note: Dowel pins are factory installed
when the clutch is supplied with the INDEX
DRIVE.
