INSTALLATION (continued)
5. Tighten the Set Screws (Item 16) to the recommended
torque (See Table 4).
NOTE: In severe use applications, the Tooth Clutch may
tend to move axially along the shaft. To prevent this
axial movement, confine the Tooth Clutch between
its shoulders or insert spring pins through the
clutch hub into the shaft.
Tooth Clutches may be mounted horizontally or
vertically. Nexen recommends the Drive Flange
face up to enhance spring return function when
mounting Tooth Clutches in the vertical position.

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.
