AIR CONNECTIONS
Figure 4
Figure 5
4-WAY CONTROL VALVE
1. If the brake is to be set when the solenoid is de-
energized, connect the port marked 2to the brake
and the port marked 4to the clutch (See Figure 3).
2. Connect the air supply line to the inlet port (marked
1) (See Figure 3).
NOTE: For quick response, Nexen recommends a quick exhaust valve and short air lines between the Control
Valves and the FMCB. Align the air inlet ports to a down position to allow condensation to drain out of the air
chambers. The metric FMCB has ISO 7/1-Rc 1/8 ports.
5-WAY CONTROL VALVE
1. If the brake is to be set and the clutch is to be OFF
when the solenoid is de-energized, connect the port
marked 4to the brake and the port marked 2to the
clutch (See Figure 4).
2. Connect the brake air supply line to the port marked
5and the clutch air supply line to the port marked 3
(See Figure 4).
3-WAY CONTROL VALVES
1. Install a 3-Way N.O. Control into the brake inlet
port and a 3-Way N.C. Control into the clutch inlet
port (See Figure 5).
2. Connect the air supply line to the inlet port (marked
IN) on top of the 3-Way N.O. Control and an air
supply line to the inlet port (marked IN) on the side
of the 3-Way N.C. Control (See Figure 5).
NOTE: When a 3-Way N.O. Control is de-energized, air
flows directly to the brake. When a 3-Way N.O. Control
is energized, air exhausts from the brake.
Whena 3-WayN.C.Controlisde-energized,air exhausts
from the clutch. When a 3-Way Control is energized, air
flows to the clutch.

LUBRICATION
LUBRICATOR DRIP RATE SETTINGS
NOTE: Thesesettingsarefor Nexensupplied lubrica-
tors. If you are not using a Nexen lubricator, calibra-
tion must replicate the following 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: Pneumatically actuated decived requre clean, pressure regulated, and lubricated air for maximum perfor-
mance and long life. The most effective and economical way to lubricate the Metric FMCB is with an Air Line
Lubricator, which injects oil into the pressurized air, forcing an oil mist into the air chamber.
Located the lubricator above and within ten feet of the Metric FMCB, and use a low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.

to the inner bearing race to remove a bearing
held by the outer race causes damage to the
bearing.
6. Clean the bearing bore of the Housing (Item 1) with
fresh safety solvent, making sure all old Loctite®
residue is removed (See Figure 11).
7. Apply an adequate amount of Loctite®680 to
evenly coat the outer race of the new Bearing (Item

8. Carefully align the outer race of the new Bearing
(Item 2) with the bore of the Housing (Item 1) (See
Figure 11).
9. Supporting the Housing (Item 1) and pressing on
the outer race of the new Bearing (Item 2), press
the new Bearing into the Housing.
10. Reinstall Retaining Ring (Item 3) (See Figure 11).
11. Support the inner race of the new Bearing (Item 2)
and press the Drive Disc (Item 4) into the new
Bearing and Housing (Item 1) (See Figure 11).
12. Reinstall Retaining Ring (Item 6) (See Figure 11).
13. Apply a drop of Loctite®242 to the threads of the
Socket Head Cap Screws (Item 13) (See Figure
11).
14. Slide the Housing (Item 1), Bearing (Item 2), and
Drive Disc (Item 4) into the FMCB and reinstall the
four Socket Head Cap Screws (Item 13) (See
Figure 11).
15. Tighten the four Socket Head Cap Screws (Item
