flywHEEl for InDUSTrIAl TyPE ovErCEnTEr ClUTCHES
• Figure 6 shows the hollowed-out appearance of the fly-
wheels made for use with overcenter type clutch power
take-off assemblies.
• These flywheels will have a recessed bore machined into the
face, and a set of tapped holes, which will be used to attach
the coupling to the flywheel. Dimensions are governed by
an SAE standard and are listed in Tables 1A and 1B, Figure
3. The “clutch size” shown in the table is the nominal clutch
facing diameter for Drive Ring Type Overcenter Clutches.
oTHEr flywHEElS
• Some engines are fitted with flywheels especially machined
for coupling to other kinds of machinery (electrical gen-
erators, torque converters, etc.), and require nonstandard
flywheel couplings. These may be purchased from third party
vendors or suppliers.

• For Goulds Pumps straight shaft keyed couplings – Ensure
that the coupling hub set screw is backed out enough to
ensure clearance for the shaft key during assembly.
• Mount the coupling assembly to the engine flywheel using
the bolts provided torqued as follows in a crossing sequence:
6½" or 7½" Flywheel – 11 lbs.-ft. (15 N.m)
8", 10" or 11½" Flywheel – 0 lbs.-ft. (7 N.m)
14" Flywheel – 50 lbs.-ft. (68 N.m)
(For other couplings follow manufacturers
recommended installation procedure.)
• Place the pump shaft key into the pump shaft (1) and align
the shaft to the coupling. Slide the pump into the coupling
until the engine adapter ring (340) contacts the engine
flywheel housing.

Flywheel Coupling Overcenter Type:
• These couplings are aligned concentrically with the flywheel
by register fit on the flywheel.
• Be sure to remove all preservatives from the engine’s fly-
wheel.
• Fit the coupling into the flywheel. Align the bolt holes and
engage coupling with register fit on flywheel. Tap coupling
with a soft heavy hammer, if necessary, to be sure that it is
seated flat against flywheel. Secure coupling tightly to fly-
wheel with capscrews and lockwasher.
InSTAllATIon of PUmP on EnGInE
• Lift pump with suitable lifting apparatus and align pump shaft
with coupling. End of pump shaft has a pilot diameter which
epermits wasy engagement of pump shaft into coupling.
