Section III. GENERAL MAINTENANCE
2-7. Electric Motor and Generator Repair
Instructions on the repair of electric motors and
generators are listed in TM 5-764.
General. Most wires on laundry units,
whether run individually or in a harness, are marked or
numbered. Be sure to tag any unnumbered wire upon
disconnection to insure proper reinstallation.
Inspection. Inspect insulation for cracks or
frayed material. Pay particular attention to wires
passing through holes in the frame or over rough metal
edges. If inspection reveals a cut or broken wire, and
the break in the wire is exposed, wire must be repaired
(d. below). If the break in the wire is in a harness,
conduit, or inaccessible area, replace the wire (e.
Testing. Test wires for continuity by
disconnecting one end from the component to which it is
attached, as this will make an open circuit. Touch the
test probes of a multimeter to each end of the wire. If
the meter shows no indication, the wire is defective and
should be repaired or replaced (d. and e. below).
Repair. Shave the insulation on the wire to
expose 1/2 inch (1.27 cm) of bare wire at both ends of
the break. Twist the bare wire together and solder the
connection. Cover the break with electrical friction tape.
Be sure to leave no bare wire exposed. If a terminal lug
breaks off a wire, replace it with an exact duplicate.
disconnecting it from the component or components to
which it is attached and remove the wire. Connect a
new wire to the component or components. If a broken
wire is part of a harness, disconnect the wire at each
end and tape the loose ends with electrical tape. Install
a new wire and attach it to the outside of the wiring
For external power requirements with
correct electrical connections, refer to wiring diagram
shown as figure 1-4.
Section IV. REMOVAL AND INSTALLATION OF MAJOR
COMPONENTS AND ASSEMBLIES
This section covers the removal and installation of the
dryer tumbler, main control box and washer-extractor.
The removal of theses components, as complete
assemblies, includes the removal of some accessories
organizational maintenance. These accessory items,
such as the control box components, electric motors,
jackshafts, pulleys, and air compressor, are all replaced
in organizational maintenance and can be removed
and/or installed after the major components are
removed from the trailer. When removing the washer-
extractor assembly from the trailer, the sheaves,
motors, and related components, mounted on the back
of the washer itself, should be removed with the washer
to insure better balance while suspended.
2-10. Dryer-Tumbler Assembly
Ref to figure 2-13 and remove the air
compressor and bracket.
