Scrub System 315Service Manual – CS7000
d. Push the Brush back against the spring and insert
a stiff temporary Retaining Wire (paper clip or
T-pin) through the access hole in the end cover.
(Remove silicone sealer from the holes.) The wire
must go through the holes in the brush holder
just in front of the Brush to hold the Brush back
against the spring pressure.
10. Install the other three Brushes.
11. Reinstall the Wave Washer. Make sure the bottom
edges of the Wave Washer contact the outside bearing
race as shown.
12. Reinstall the end casting in stages as follows.
a. Reinstall the end casting with brushes far enough
into the frame so the brushes will contact the
commutator when the temporary retaining wires
are removed, then remove the retaining wires.
b. Press the end casting into the frame, leaving
about a 1/8” gap between the frame and end
casting. Make sure to align the witness marks on
the end casting and frame as noted in step 3.
c. Reinstall the threaded rods, lock washers and hex
nuts, but don’t tighten the hex nuts yet.
