LUBRICATION
CAUTION
LUBRICATOR DRIP RATE SETTINGS
NOTE
Nexen pneumatically actuated devices require clean, pressure regulated air for maximum performance and
life. All seals in Nexen pneumatically operated devices are lubricated for life, and do not require additional
lubrication.
However, some customers prefer to use an air line lubricator, which injects oil into the pressurized air,
forcing an oil mist into the air chamber. This is acceptable, but care must be taken to ensure once an air
mist lubrication system is used, it is continually used over the life of the product as the oil mist may wash
free the factory installed lubrication.
Locate the lubricator above and within ten feet of the product, and use low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.
Nexen product's bearings are shielded and pre-lubricated, and require no further lubrication.
These settings are for Nexen supplied
lubricators. If you are not using a Nexen
lubricator, calibration must follow the
manufacturer's suggested procedure.
1. Close and disconnect the air line from the unit.
2. Turn the Lubricator Adjustment Knob
counterclockwise three complete turns.
3. Open the air line.
4. Close the air line to the unit when a drop of oil forms
in the Lubricator Sight Gage.
5. Connect the air line to the unit.
6. Turn the Lubricator Adjustment Knob clockwise until
closed.
7. Turn the Lubricator Adjustment Knob
counterclockwise one-third turn.
8. Open the air line to the unit.
DRIVE FLANGE ASSEMBLY
The Drive Flange Assembly has been prelubricated and
does not require additional lubrication at start up. The
amount of lubrication is sufficient to maintain the proper
coefficient of friction at the Balls and Detents.
The Drive Flange Assembly must be disassembled if lubrica-
tion becomes necessary (See PARTS REPLACEMENT).
Spread recommended lubricants evenly (about 1/8" [3.2
mm] thick by 1/8" [3.2 mm] wide) over Drive Flange Balls,
Ball Track, and Drive Ring Detents (See Table 5 for recom-
mended lubricants).

Chevron SRI
Amoco Rykon Premium Grease #2
Exxon Unirex #2
Shell Dolium Grease #2
Texaco Premium #2
CAUTION
Do not over lubricate Drive Flange Assembly.
Over lubrication creates a hydraulic effect
within the Torque Limiter that will adversely
effect the break-away torque.
