Low

When

range
the

driving

is
locked
to
the
low

ratIO

In
1

range
the

reaT
dutch

is

applied
and
the
low
and
reverse
brake

holds
the

connecting
drum
and

rear

planet
carrier
from

rotating
The

power
flow
takes

place
through
the

input
shaft
and
into
the
rear
dutch

Rotation

of
the
rear
clutch
drives
the

rear
clutch
hub

and
front
internal

gear

The
front
internal

gear
rotates
the

front

planetary
gears
clockwise
to

cause

the
sun

gear
to
rotate
counter

clockwise

Counterclockwise
rotation
of
the

sun

gear
turns
the
rear

planetary
gear

clockwise

The
rear

planet
carrier

splined
to

the

connecting
drum
is
held
from

rotating
by
the
low
and

reverse
brake

The
clockwise
rotation
of
the
rear

planetary
gears
therefore
rotates
the

rear
internal

gear
and

internal
drive

tlange
The

internal
drive

tlange
is

splined
to
the

output
shaft
and
rotates

the

output
shaft
clockwise
However

the

output
shaft
rotates
at
a

lower

speed
compared
with
that
of
the

input

shaft
This
is

caused

by
the
fact
that

the
front

planet
carrier
rotates
at
the

same

speed
as

the

output
shaft
in
the

same
direction
since
the
carrier
is

splined
to

the

output
shaft
The

front

internal

gear
and

planetary

gear
as

sembly
are

rotating
in
the

same
direc

tion
but
the

planet
carrier
is

rotating

at

a

speed
slower
than
the

ring
gear
So

the

gear
ratio

of
this

speed
range
is
a

combination
of
the
ratios

provided
by

the
front

rear

planetary
gear

COMPONENT
PARTS

The

consists
of

many

small

parts
that
are

quite
alike
in

construction

yet
machined
to

very

close
tolerances
When

disassembling

parts
be
sure
to

place
them
in

order
in

a

part
rack
so

they
can
be
restored
in

the
unit
in
their

proper
positions
It
is

also

very

to
