odern burner unit-V3 (MBU-V3) operators, listen up. You just got a few more
maintenance duties. The Army says it’s now your job to remove and replace the MBU-V3’s
compressor, control panel and fuel delivery block. It’s also your job to inspect, test and
adjust them.
Why the additional duties? In the past, the MBU-V3 was SMR coded Z, nonreparable,
in the repair parts and special tools list (RPSTL). That led to a slew of turn-ins and new
requisitions. Soon MBU-V3 stocks ran low. So, to save money, avoid shortages and improve
mission readiness, the Army changed the coding to make the item reparable. The upshot
is the operators were assigned three more maintenance tasks. This saves valuable time: It
shortens the MBU’s repair cycle and returns the MBU to service pronto.
The 92G (food service operations specialist) MOS program of instruction will be revised
to include these maintenance tasks, inspection, testing and adjustment.
Replacing the Control Panel
1.
Unplug the MBU-V3’s power cable. Make sure the burner unit
is cool to the touch.
2.
Turn the
screw on
the locking
arm of the
hinged
control
panel (1).
Open the
panel.
3.
The cable harness (6) runs from the back of the panel into the
MBU. Disconnect the eight connectors (5) with their color-coded
wires. Remove the green ground wire (7) from the control panel.
4.
Remove the snap rings (2) from the hinge pins (3) with a
screwdriver. Remove the hinge pins from the frame (4).
5.
Remove the control panel from the frame.
6.
Put the replacement panel into position. Insert the hinge pins
through the frame. Fasten the hinge pins with the snap rings.
7.
Plug in the eight connectors at the end of the cable harness.
Follow the color coding of the wires. Reconnect the ground wire.
8.
Close the hinged control panel. Turn the screw on the locking
arm to hold the panel in place.
