Series 7886 High-Capacity & 7887 Meter Registers
SECTION 4. 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.
a. Wheel Shaft
b. Anti-Topping Finger Group Shaft
c. Reset Finger Group Shaft
d. Clutch Group Shaft
e. Pinion Shaft
2. Temporarily install the base plate and meter register in
the housing and check for proper engagement and
freedom of movement of:
a. All gears on gear plate.
b. Output bevel gear on gear plate with the bevel drive
gear on drive shaft.
c. 57 tooth gear on clutch assembly with gear on right
wheel assembly.
d. Gear drive shaft with gear train 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.
E. LUBRICATION.
I. Recommended Lubricants

Oil: Chemlube 201 or equivalent with a temperature range of
-65°F to +275°F (-54°C to +135°C).
Grease: Vischem 352 or equivalent with a temperature range
of -65°F to +300°F (-54°C to +149°C).
Note: All lubricants used in the register must be of a type
which remains fluid over the full temperature range
to which the register will be subjected. Also, they
should not oxidize or dry out leaving a gummy or
perceptible residue.
If the Chemlube 201 oil lubricant is not available, a substitute
with equivalent properties may be used. To assist field
personnel in obtaining suitable lubricants for the meter
register and ticket printers, the following list showing equi
valent lubricants has been prepared:
OIL
AEROSHELL FLUID
REGENT SPINTEX OIL
GARGOYLE ARCTIC OIL
CASTROL HYSPIN

Oil: All points indicated as "Oil" on Figure 6 should be
lubricated with oil as described above. This includes all
shafts, studs, and bosses on which a moving part bears.
Grease: Grease should be applied to all points indicated as
"Grease" on Figure 6. This includes gears and the no-back
ratchet and pinion.
Note: The oil and grease should be applied with a small
brush to make certain that all areas will be properly
lubricated. In this manner, the amount of lubricant
being used will be more easily controlled.
