INSTALLATION INSTRUCTIONS TYPES
F AND S CLUTCHES
ASSEMBLY INSTRUCTIONS
See Fig. 3 for required assemblies
Important: To obtain maximum accuracy in
positioning the DRIVEN MEMBER, the lNDEX
DRIVE "CAM SHAFT" must be in the EXACT
CENTER OF DWELL position. See CAMCO
drawing applicable to the Index Drive Model.
1. Insert PLUNGERS ❼ into SPRINGS
Ω
and
install the assemblies in the BODY pock-
ets. Test tor free movement of the plungers.
Lightly lubricate the body pockets, springs
and plungers with Mobilgrease 77 or
equivalent.
Caution: Do not overlubricate.
Heavy lubrication may prevent clutch
disengagement.
2. Install the FLANGE PLATE
∑
into the
DRIVE PLATE
∏
. Lightly lubricate both
sides of the DRIVE PLATE and the ma-
chined face of the BODY with Mobilgrease
77 or equivalent.
3. Align the PLUNGERS with the tapered
seats in the DRIVE PLATE.
4. Type S Clutch: Insert mounting screws
through the FLANGE PLATE into the
tapped holes in the BODY
π
. Alternately
tighten the screws until flange plate is
seated on the BODY.
4A. Type F Clutch: Insert mounting screws
through the BODY ❻ and FLANGE PLATE
into the tapped holes in the INDEX DRIVE
flange. Alternately tighten the screws until
the FLANGE PLATE is seated on the BODY.
5. Assemble the DETECTOR PLATE
∫
on the
clutch BODY and secure both the DETEC-
TOR PLATE and the PLUNGERS with the
detector mounting screws.
Note: Type F Clutch only. If alternate
assembly, with the clutch BODY mounted
on the INDEX DRIVE flange is required,
reassemble as follows:
Remove the mounting screws. Insert the
mounting screws through the FLANGE
PLATE first, and then the BODY, into the
tapped holes in the INDEX DRIVE flange.

3. Align the PLUNGERS with the tapered
seats in the DRIVE PLATE.
4. Type C Clutch COUPLING: Insert mounting
screws through the FLANGE PLATE into
the tapped holes in the BODY
π
. Alter-
nately tighten the screws until the flange
plate is seated on the BODY.
4A. Type FC Clutch COUPLING: Insert the
mounting screws through the BODY ❻ and
FLANGE PLATE into the tapped holes in
the INDEX DRIVE flange. Alternately tighten
the screws until the FLANGE PLATE is
seated on the BODY.
5. Assemble the DETECTOR PLATE
∫
on the
clutch BODY and secure both the DETEC-
TOR PLATE and the PLUNGERS with the
detector mounting screws.
6. Install the assembled clutch on the output
shaft or flange of the INDEX DRIVE.
7. Press the dowel pins in the HUB ➊ until
they protrude approximately .125" beyond
the machined face of the HUB.
8. Insert the HUB mounting screws through
the HUB into the tapped holes in the
DRIVE PLATE. Tighten the HUB mounting
screws.
9. Drive the dowel pins flush with the HUB
shoulder.
WARNING: Hub mounting screws and
dowel pins must not protrude from the
drive plate as they may lock against the
adjacent surface, making the clutch
inoperative.
10. Place driven shaft in HUB ➊. The respec-
tive shafts should not protrude from the
face of the HUB or the FLANGE PLATE.
Tighten clamp screws.
11. Note: Shafts must be aligned within .003"
TIR, and there must be an airgap between
the DRIVE PLATE and CLUTCH BODY of
.004" to .01". Check clearances with a
shim or feeler gauge throughout the full
diameter of the clutch.
Warning: Excessive misalignment will
cause the coupling to lock.
12. Test for proper torque setting.
