INTRODUCTION
Transmissions
have been designed
for
smooth
operation
and dependability in
marine
use.
The
transmission
is
self-contained, having an oil
pressure
system
and oil supply completely
separated
from
engine lubricating oil
systems.
Translllission
oil
under
pressure
is
used to
engage a forward
or
reverse
drive.

INSTALLATION
A.
The installation
instructions
below
are
for
use
when the
original
transmission
has
been
removed for
servicing
and
must
be
re-
installed,
or
when the
transmission
unit
is
to be adapted
as
non-original equip-
ment to a
marine
engine.
B.
It
is
important that the engine and
trans-
mission
rotations
are
matched. The
direc-
tion of rotation of an engine
is
defined in
this
manual
as
the
direction
of
rotation
of the engine
crankshaft
as
viewed from the
output end of the
transmission.
A
clock-
wise
rotation of the engine
is
a right hand
rotation and a counterclockwise rotation of
the engine
is
a left hand rotation.
A
letter
"R"
or
"L"
appearing on the
transmission
serial
number
plate
illus-
trated
in Section I, "SPECI
FICA
TIONS",
indicates
whether
the
transmission
is
for
use
with a right
or
left hand rotating
engine.
C. The hydraulic
transmission
is
attached to
the engine in the following
manner:
1.
Insert
two
3-1/2"
studs
in opposite
transmission
mounting holes in the
engine
adapter
plate.
2.
Place
the
transmission
against
the
studs
so
that the
studs
go through two of the
matching
holes
in the
transmission
housing flange.
3.
Slide the
transmission
along the
studs
toward the engine so that the spline on
the shaft
at
the front
ofthe
transmission
enters
the matching splined hole in the
engine vibration
dampener.
ward
drive
is
through a multiple
disc
clutch
arrangement,
while the
reverse
drive
utilizes
a
reverse
clamp
band and planetary
gear
train.
The
transmission
oil
is
Circulated and
cooled through a
separate
external
oil
cooler
core,
which
is
in
turn
cooled
by
the engine
water.
Paragon
transmissions
are
furnished
with
either
direct
drive
or
reduction
gears.
Gear
reduction
ratios
and
corresponding
model identification
numbers
are
listed
in
Section I, under
"SPECIFICA TIONS".
4. Install and tighten four bolts with lock-
washers
through the
transmission
housing flange into the engine
adapter
plate. Remove the
3-1/2"
studs.
Install
and tighten the two
remaining bolts
with
lockwashers
through the
trans-
mission
housing flange.
D.
The
transmission
and
propeller
shaft
cou-
pling
must
be
carefully
aligned before the
propeller
shaft
is
connected to the
trans-
mission,
in
order
to avoid vibration and
consequent damage to the
transmission,
engine, and boat hull during
operation.
To align the coupling, move the
propeller
shaft, with attached coupling flange, toward
the
transmission
so
that the faces of the
propeller
shaft coupling flange and
trans-
mission
shaft coupling flange
are
in
con-
tact.
The coupling flange faces should be
in contact throughout
their
entire
circum-
ference.
The total runout
or
gap between
the faces should not
exceed
.002" at any
point.
If
the runout
exceeds
.002",
reposi-
tion the engine and
attached
transmission
by
loosening the engine
support
bolts and
adding
or
removing
shims
to
raise
or
lower
either
end of the engine.
If
necessary,
move the engine sideways to
adjust
the
runout
or
to align the coupling flange
faces
laterally.
Tighten the engine
support
bolts and
recheck
the alignment
of
the
coupling before bolting the coupling flanges
together.
Connect the coupling flanges with
bolts,
lockwashers,
and nuts.
E. Connect the oil
cooler
lines
to
the
trans-
mission.
F. Connect the
shift
control
cable
from the
cockpit
control
station
to the
transmission
control
valve
lever,
shown in
Figure
on
page 5.
Place
the
transmission
control
valve
lever
in the
neutral
