4.
Remove the crossbeam cover.
5.
Disconnect the Sweep brake and motor encoder cables from their harnesses in the wire-way.

8.
Remove the three bolts and nuts that secure the sweep motor to the gearbox and separate the sweep
motor from the gearbox.
9.
Clean all surfaces of the sweep motor and gearbox with a cloth dampened with a water-based cleaner.
10.
Check the gearbox for any signs of oil leakage. Repair as needed.
11.
Check for loose bolts (6) holding the gearbox flange to the gearbox housing. Tighten as needed.
12.
Check the sweep motor key for excessive wear. 50 Hz gearboxes with serial numbers before 110912-1
(11/9/2012) and 60 Hz before 102812-1 (10/28/2012) also have an anti-fretting sleeve (088-004-518)

gearbox (sight glass side).
17.
Install the three bolts and nuts to secure the sweep motor to the gearbox and tighten.
18.
Rotate the gearbox output shaft by cranking the motor shaft 20 revolutions to develop a new wear
pattern on the gears.
