JUDGEMENT

High
stall
revolution
more

than

standard
revolution

If
the

engine
revolution
in
stall

condition
is

higher
than
the
standard

values
it

indicates
that
one

or
more

clutches
in

the
transmission
are

slipping
and
therefore
no
further
test

is

required

For
the

following
abnormalities

the

respective
causes
are

presumed

High

all

ranges
low

and
reverse

brake

slipping

To

determine
which
is

slipping

front
clutch
or
low

and
reverse
brake

a
road
test
is
nceded

If
whilc

coasting
after

starting

with
the
lever
in
1

range
engine

braking
does

not
work

properly
the

low
and

reverse
brake
is

slipping

Otherwise
the
front
clutch
is

slipping

Slipping
of
the
band
brake
is

diffi

cult
to
ascertain

However
if
it

occurs

with
the
lever
in
2

range

engine

revolution
increases

Jp
to
thesarne

level
as
in

I

strange
It

is

impossible

to
check

it
in

test
