PREPARATION FOR ASSEMBLY
OF PUMP ON ENGINE
• Clean face and register fit of flywheel housing and flywheel
as necessary to remove all grease, dirt, or rust (and all
traces of rust preventative) which would interfere with
installation of pump and/or prevent correct alignment. If
flywheel is fitted with a pilot bearing for a transmission shaft,
remove and discard. The pilot bearing is not required for
installation of the pump end, and could interfere with the
pump shaft.
• Examine shaft spline closely. Use a file, if necessary, to
remove any burrs that would prevent coupling from sliding
freely onto the shaft.
• Lubricate pump shaft spline sparingly with light grease.
• Slide the coupling onto shaft until it is stopped against the
shaft.
• Measure the distance from the engine side of flywheel
coupling adapter ring to the mounting face of the pump
bracket. Refer to Figure 4 below,
Dimension “A”
.
• Next, measure depth from face of flywheel housing on
engine, to face on flywheel against which coupling will be
bolted. Refer to Figure 4 below,
Dimension “B”
.
Pump measurement must be less than engine measurement
or axial interference will result in thrust force on engine crank
shaft bearings. Simply stated,
Dimension “A” must be less
than Dimension “B”
.
INSTALLATION OF COUPLING ON FLYWHEEL
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
flywheel.
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
flywheel 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 permits easy engagement of pump shaft into
coupling.
• Reach into pump suction opening and rotate impeller
slightly until the splines on the shaft will engage the
coupling. Verify that there is no gap between bracket and
flywheel housing faces. Rotate pump as necessary to align
bracket holes with engine. Install capscrews and bolt pump
end securely to engine.
NOTE: If any interference, or incompatibility of parts is
detected during installation, DO NOT proceed with
assembly. Direct the problem to your nearest Berkeley
Professional Dealer.

NOTE: When the coupling is correctly assembled,
the hub will not bottom out on the shaft splines.
If it should bottom out, reverse the coupling on
the shaft as shown to gain clearance.
Dimension "A" MUST be
less than dimension "B".
