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.

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.

CAUTION
These settings are for Nexen supplied
lubricators. If you are not using a Nexen
lubricator, calibration must follow the
manufacturer's suggested procedure.
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.
SPlIne.
Although the Spline has been lubricated at the factory with
a high temperature, anti-seize lubricating compound, Nexen
recommends periodic lubrication of this component to insure
smooth clutch engagement and disengagement.
NOTE: Clutch must be disassembled to lubricate Spline
(See Disassembly instructions).

aIr COnneCTIOnS
Although “5HP-SP” Tooth Clutches are air actuated with a
maximum operating air pressure of 80 PSI, use only enough
air pressure to deliver ample torque for the application.
Operating air pressures over 80 PSI will eventually cause
bearing and seal damage.
Due to bearing seal drag, the cylinder/piston assembly
will rotate, resulting in hose breakage when the clutch is
engaged. For Models 30 through 60, resting the hose
against a support mounted parallel to the clutch centerline
stops this rotation.
On Models 70 and 80, where seal drag is more apparent,
have a 3/8-16 hole tapped 180
o from the air inlet. Then
install a bolt or stud in this hole. Resting the bolt or stud
against a support relieves stress on the hose.
