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.
The
for-
III. 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
of
the
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 sep&.rate
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
"SPECIFICATIONS".
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
position
and
