66Service Manual – SC900 34 - Scrub System, Cylindrical
Note: The wave washer (J) ts between the rotor
bearing and the end cap. When placing it in
the end cap before assembly, note that the
ngers (K) face toward the bearing.
The picture to the right is only for reference.
It is easier to place the washer in the end
cap than it is to leave it on the bearing.
13. Place the wave washer (J) in the bearing
pocket of the end cap with the ngers (K)
facing toward the bearing. Use a Rare Earth
magnet (L) on the opposite side of the cap
to hold the washer in place. (A less powerful
magnet can be used, but a Rare Earth
magnet is powerful enough to hold itself in
place.)
14. Place the end cap over the top of the motor,
and lower it until the coil springs prevent
you from lowering it any farther.
• Make sure to realign the marks (A)
that you made on the motor before
disassembly.
• When the brushes are compressed in
this manner, they are too wide to t
the cap all the way into the motor. The
coil springs will catch on the edge of the
motor housing.
15. With the end cap on the motor as far as it
will go, begin removing the pins (H) to allow
the brushes to move toward the commutator.
16. Press the end cap down on to the bearing.
17. Install the two long screws (B) that secure the top cap to the bottom cap.
18. Remove the permanent magnet.
