Tweco 2460 Heavy Duty CC CV Control Wire Feeder - Manual (Page 35)

trol Box (in the 2000 Series composite assembly).
See Figure 6 and instructions for removing feed-
head and motor from Control Box.
NOTE: There are two possibilities for
wire feed motors, depending upon which
manufacturer’s stock was used for the
particular assembly. The removal from
the Control Box is the same for both mo-
tors, but the procedure for changing
brushes is different.
1. Remove six screws from the top and side of the
Control Box which holds the Control Box Cover in
place. Loosen the screws (2) at the bottom of the
Cover, to allow the Cover to slip up off from the
screws in the slots provided.
2. Disconnect the power supply wire from the gun
receptacle. Remove the four screws and lockwash-
ers which secure the Feedhead Mounting Plate to
the side of the Control Box. This will allow the
Feedhead assembly (including the motor) to pull
straight out of the Control Box, to a position (see
Figure 6) where the motor brushes may be serviced.
3. The Bodine gear motors are equipped with a
vent for the gearbox. The vent hole is plugged and
does not have to be removed for operation.
Bodine Motor Brush Inspection and Installation —
See Figure 7 — The brushes should be inspected
every 300 hours of operation. When brushes are
worn to about 3/8 inch (9.5 mm) in length, new
brushes should be installed. (Refer to Parts List for
brush part numbers.) See Figure 7 for following
procedure.
CAUTION: Neglect in brush mainte-
nance may cause damage to commuta-
tor in the motor if allowed to wear away
completely.
1. See Step 1 on Figure 7. Lift and remove the
Brush Cap by prying the Rivet out of the hole in the
End Shield. This will reveal the brush assembly in
place as in Step 2.
2. Using long-nosed pliers, grasp the Spring Re-
taining Bracket. Slightly push the Retaining Spring
down and toward the brush. When the Bracket
unhooks from the Brush Box, lift the Retainer/Spring
out.
3. Using long-nosed pliers, grasp the connector on
one end of the brush pigtail and pull it straight
up
.
Disconnect it from the clip on the side of the Brush
Box. The Brush may be removed at this time.
