FRICTION FACING & CALIPER ASSEMBLY
FIGURE 9
FIGURE 10
REFER TO FIGURES 9 - 10.
1. Place a 1/16" [1.6 mm] shim between the friction
facings and the Rotor Disc (Item 2). As you rotate
the Rotor Disc past each caliper, check for equal
clearance at all positions.
2. Use the Machine Screw (Item 10) to secure the
Friction Facing to the caliper and install a Friction
Facing (Item 9) onto each remaining caliper half.
Tighten the Machine Screw to 18-19 in-lbs [2.0-2.1
Nm].
3. Use Lock Washers ( Item 19) and Socket Head Cap
Screws (Item 18) to attach the caliper halves at each
caliper position. Tighten the Socket Head Cap
Screws to 7 ft-lbs [9.5 Nm].
4. Install a Tee Fitting (Item 16) or an Elbow Fitting
(Item 15) into each remaining caliper half.

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.
NOTE
DO NOT lubricate the caliper diaphragms. If you use a lubricant on the air line for the controls, use a lubricant
that is compatible with the silicone diaphragm.
