Warner Electric Wheel-Brakes (Std) - Manual (Page 11)

Adjust Armature Depression
If the depression is less than 1/8”, the difference must
be made up by placing shims (Figure 2-19) under the
armature retaining ring. If the depression is more than
3/16”, place a hardened bearing spacer between the
inner bearing and the bearing shoulder on the axle.
Warner Electric does not supply bearing spacers.
If wedges have been used under the armature to check
depression, be sure to remove them.
Cleaning
Clean all grease and oil from the brake drum surface,
armature face, magnet face, and brake lining with
carbon tetrachloride before mounting wheels. Pack
wheel bearings with a good grade of bearing grease.
Be sure wheel bearings are tight, as loose bearings
cause grabby, erratic brakes. Under no circumstances
should a grease gun be used; and if any grease fittings
are present, remove them and plug holes before
releasing the unit for service.
Electrical Connections
Make necessary electrical connections in accordance
with recommended wiring diagrams CWA-001 through
CWA-008 furnished separately.

Using GO-NO-GO Gauge
Step 6 The armature gauge is provided with a Go-
No-Go gauge (Figure 2-18) presenting an
easy manner of checking for correct depres-
sion. The small end of the pin is 1/8” in diam-
eter and should slip between the gauge
frame and the collar. The large end of the pin
is 3/16” in diameter and should not slip
between the gauge frame and collar.
