May have to add a bit at a time, anyway hope this helps.
Machine Cleaning PARK-O-METER MECHANISMS
Main spring barrel cleaning Never place this part in solvent. Clean with stiff bristle brush, and
add 3 to 5 drops of mainspring oil to the coils. (Flexing
of coils is advisable to spread oil: Clamp barrel
flat on table and use wind crank to run up and reverse
coils a few turns, repeating several times.)
TIMER. This unit can usually be returned to the
meter as is. When needed, the timer can be serviced
economically through the company exchange plan. If
desired, the timer may be removed from its case, and
a very small quantity of timer oil applied to each of
the 6 pivots (both sides).
CAUTION. Protect cleaned mechanisms from dust
while stored. Check gaskets and dust out meter case,
before installing cleaned mechanism.
Most customers use timers for as long as they operate
properly, which will be for several years. Timers may
then be returned for factory rebuilding, which includes
cleaning, lubrication, adjustment, plus all necessary
parts.
For those who would like to clean their timers, the
following suggestions are made: Remove the timer
unit from its protecting case. Do not take the unit
apart.
Process in the cleaning machine at a time when you
have fresh cleaner and rinse in the tanks.
Use the fine mesh divided basket. Lay timer unit with
threaded bushing down and hairspring to outer edge
of basket. Do not lay one on top of another. Eight
to ten units may be processed at one time.
Run in cleaner IM minutes, at moderate to fast speed.
Reverse the basket at each count of 10. Rinse and
dry the same as for mechanisms, using slow speed
on drying.
LUBRICATION: Use timer oil. Oil sparingly: 6
pivots on both front and back plates, including balance
wheel cups; 2 points where pallet fork contacts
the escape wheel; verge pin on balance wheel. BE
C A R E F U L NOT TO GET OIL O N HAIRSPRING
COILS. This will cause coils to stick together, and
speed up timing. SUGGESTION: When oiling balance
wheel cups, wipe instrument oiler needle with
tissue to remove surface oil that might contact hairspring.
Jeweler's stick oiler may be used.
Clean plastic and stainless case using cloth moistened
with rinse solution.
If timer does not operate satisfactorily after this treatment,
it indicates need for adjustment or parts replacement.
G E N E R A L L U B R I C A T I O N I N F O R M A T I O N:
Types of oil for instrument use are constantly being
improved in the laboratories of oil and chemical
companies. These oils are continuously being tested
to determine those best adapted to your Park-OMeters.
The oils supplied under the following three
types will always be the best available for the application:
1. Mechanism (Mech) Oil
2. Timer Oil
3. Mainspring (MS) Oil
Use oil sparingly: An instrument oiler is recommended
for proper application.
DO NOT OIL the following locations:
1. Idler arm gear and stLid
2. Idler arm shaft
,3. Portion of rotator shaft supporting
cam assembly
4. Spider pawl
.5. Index pawl bearings
6. Signal latch bearings
7. Coin trip lever
8. Case locks
