INTRODUCTION
A.
GENERAL.
These
instructions
are
for
servicing
the
Series
7886
High-Capacity
and
Series
7887
Meter
Registers
designed
and
manufactured
by
the
Veeder-Root
Company,
6th
Avenue
at
Burns
Crossing.
P.O.
Box
1673,
Altoona,
PA
16603.

When a vertical
bar | appears
adjacent
to
text
or
illus
trations,
information
has
been
added
or
changed
at
the
last
issue date.
Note:
Consult
Veeder-Root
on
any
unusual
application,
installation
or
possible
modification
of
this
basic
design.
Every
Meter
Register
is
thoroughly
tested
at
the
Veeder-Root
factory
and
by
the
meter
manufacturer
when
installed
on
the
meter.
However,
like
any
precision
mechanism,
it
requires
periodic
care
to
ensure
maximum
service.
This
manual
is
for
use
in
areas
where
factory
rebuilding
facilities
and
adequate
exchange
stocks
are
not
readily
accessible.
Where
manufacturer's
replacement
stocks
are
available,
it
is
important
that
no
attempt
be
made
to
repair
any
meter
register
defective
within
the
terms
of
the
warranty
as
by
doing
so,
the
warranty
is
void
and
the
user
is
deprived
of
the
protection
provided
by
the
warranty.
It
is
recommended
that,
when
possible,
meter
registers
be
replaced
and
the
defective
unit
returned
to
the
meter
manufacturer.
Note:
See
Section 6 for
complete
Damage
Claims
and
Warranty.
IMPORTANT!
The
instructions,
photographs
and
drawings
in
Sec
tions 4 and 5 are
based
on
the
Series
7887
Meter
Register.
With
the
exception
of
an
additional
count
ing
wheel,
the
Series
7886
High-Capacity
Meter
Register
is
physically
similar
and
the
same
proce
dures
should
be
followed.

DESCRIPTION
A.
GENERAL.
1.
Physical.
The
Series
7887
Meter
Register,
Figure
1,
displays
a
running
account,
final
total
and
accumulated
total
of
the
quantity
of
liquid
product
delivery.
Contained
in
a4"x
10"
diecast
enclosure,
individual
delivery
data
is
displayed
on
five
3/4"
high
figures
while
totalizer
information
is
recorded
on
eight 1 /8"
high
figures.
Reset
of
the
Meter
Register
is
accomplished
through a reset
knob
on
the
right-hand
side
of
the
unit.
2.
Operational.
The
Meter
Register
is
operated
by a drive
shaft
connected
to a group
of
gears
on
the
gear
plate
which
converts
the
drive
revolutions
to
the
appropriate
ratio.
The
output
bevel
gear of the
group
drives a bevel
gear,
Figure
5,
which
is
connected
to
the
drive shaft
and
clutch
assembly.
In
rotating,
this
shaft
drives a gear
on
the
clutch
assembly
which
in
turn
drives a gear
on
the
right
(unit)
wheel
assembly.
Revolutions
are
then
accumulated
on
the
wheels.
In
addition,
this
rotating
shaft
drives
the
bracket
group
connected
to
the
accumulative
totalizer
shaft,
thus
both
displays
are
driven
from
the
same
source,
assuring
accurate
recording
of
information.
During
the
reset
operation,
the
clutch
is
disconnected
from
the
drive
shaft, a shutter
moves
into
place
covering
the
display
wheels
and
reset
fingers
engage
heart-shaped
cams
on
the
individual
wheels
to
move
them
back
to a zero
position.
In
addition, a set
of
anti-topping
fingers
engages
the
wheels
to
prevent
jamming.
At
the
completion
of
reset,
the
display
wheels
will
read
all
zeros,
and
the shutter
will
rise
to
the
normal
operating
position.
The
clutch
will
engage
the
drive
shaft
to
transfer
the
information
from
the
next
delivery.
The
totalizer
wheels
will
be
unaffected
by
this
reset
operation,
thus
displaying
an
accurate
measure
of
the
accumulated
totals
of
many
deliveries.

is
displayed
on
six
5/8"
high
figures
while
totalizer
information
is
recorded
on

Reset
of
the

is
accom

2.
Operational.
The
Meter

is
operated
by a drive
shaft
connected
to a group
of

on
the
gear
plate
which
converts
the
drive
revolutions
to
the
appropriate

The
output
bevel
gear
of
the
group
drives a bevel
gear,

which
is
connected
to
the
drive shaft
and
clutch
assembly.
In
rotating,
this
shaft
drives
agear
on
the
clutch
assembly
which
in
turn
drives a gear
on
the
right
(unit)
wheel
assembly.
Revolutions
are
then
accumulated

the
wheels.
In
addition,
this
rotating
shaft
also
drives
the
bracket
group
connected
to
the
accumulative
totalizer
shaft,
thus both
displays
are driven
from
the
same
source,
assuring
accurate
recording
of
information.
During
the
reset
operation,
the
clutch
is
disconnected

PERIODIC
INSPECTION
(For
Series
7886
High-Capacity
and
Series
7887
Meter
Registers)
A.
GENERAL.
The
Meter
Register
is
fully
lubricated
and
properly
adjusted
at
manufacture.
However,
periodic
clean
ing
and
lubrication
are
required.
Judgement
of
the
intervals
at
which
the
meter
register
requires
such
service
must
necessarily
be
left
to
the
individual
user
due
to
varying
conditions
of
service.
Under
normal
conditions,
this
will
be
at
least
once a year,
or
after
each
2-1/2
million
units
of
measure
delivered,
whichever
comes
first.
B.
DISASSEMBLY
PRIOR
TO
CLEANING.
Remove
the
meter
register
from
its
housing
as
follows:
1.
Remove
the
bolts
securing
the
cover
(if
present)
to
the
top
of
the
housing.
These
bolts
are
hex
head
and
are
located
at
the
four
corners
of
the
bottom
of
the
housing.
Remove
the
cover.
2.
Remove
the
three
button-head
bolts
securing
the
meter
register
to
the
housing.
Remove
the
meter
register.
3.
Remove
the
screws
securing
the
gear
plate
to
the
bottom
of
the
housing.
Remove
the
gear
plate.
C.
CLEANING.
CAUTION:
DO
NOT
USE A WIRE
BRUSH.
1.
Wipe
bezel
crystal
with a clean
lint-free
rag.
2.
If
the
wheel
faces
are
dirty,
gently
clean
with a clean
lint-free
rag
dipped
in
mild
soapy
water.
3.
Clean
the
gears
on
the
base
plate
by
flushing
or
with
a
brush
dipped
in
solvent.
Blow
dry
with
compressed
air.
4.
Clean
housing
by
dipping, flushing
or
brushing
with
solvent.
Blow
dry
with
compressed
air.
D.
INSPECTION. A periodic
inspection
of
the
entire
meter
register,
housing
and
gear
plate
is
required
to
make
sure
that
they
function
properly,
parts
are
in
place,
and
no
binding
or
excessive
side-to-side
motion
of
shafts
occurs. A checklist
on
such
procedures
follows:
1.
Check
the
following
shafts
for
perceptible
side-to-side
motion.
Note:
Remove
the
meter
register
from
the
housing
before
checking
shaft
freedom.

that
operates
the
totalizer,
and
gear
connecting
the
drive
train
to
the
totalizer.
3.
Rotate
drive
shaft
by
hand
to
see
that
unit
operates
freely
and
then
reset,
checking
for
proper
reset
and
shutter
action.
Adjust
pointer
after
reset
as
required.
4.
Check
all
screws,
retaining
rings
and
groove
pins
to
see
that
they
are
tight
and
seated
properly.

TROUBLESHOOTING.
Table 1 is
used
to
assist
in
locating
problems
and making
repairs
and
corrections.
In
some
problems,
similar
defects
can
be
produced
by
several
causes
of
an
entirely
different
nature.
Cause
of
the
trouble
must
be
determined
and
the
correction
made.

When
disassembling
the
meter
register,
be
extremely
careful
not
to lose

will
be
greatly
lessened.
When
removing
retaining
rings
or
other
parts
from
shafts,
do
not
hold
the
shaft
with
any
tool
that
might
gouge
or

as
follows:
1.
Rotate
