5.
Label and disconnect the wiper motor wiring (15) from the wiper motor assembly (14).
6.
Procure a new wiper motor assembly, wiper arm, and wiper blade as required.
7.
Measure and record the distance from the end of the wiper shaft (9) to the spacer plate (16), and from the end of the slave
arm shaft (7) to the other spacer plate (16). These dimensions will be required when installing the new wiper motor
assembly.

Remove the spacer plates (16), wiper shaft inner nut (17), and slave arm shaft inner nut (18) from their respective shafts.
INSTALLATION--WIPER MOTOR
1.
Install the wiper shaft inner nut (17), slave arm shaft inner nut (18), and spacer plates (16) onto their respective shafts.
2.
Adjust the wiper shaft inner nut (17) and slave arm shaft inner nut (18) to attain the dimensions recorded in step 7 of the
Removal--Wiper Motor procedure in this work package.
3.
Connect the wiper motor wiring (15) to the new wiper motor assembly (14) using the labels from step 5 of Removal--Wiper
Motor as a guide.
4.
Slide the wiper motor assembly (14) into place through the pilothouse bulkhead.
5.
Secure the wiper motor assembly (14) in place using the outer plate (13), washer (12), outer wiper arm shaft nut (11), and
outer slave arm shaft support nut (10).
6.
Remove the lockouts and tagouts and turn ON the wiper motor assembly (14) to check for proper operation. Turn OFF
the wiper motor assembly when finished.
! CAUTION
Do not clamp the vise grips directly to the wiper arm shaft. Use several folds of a wiping
rag between the vise grip jaws and the wiper arm shaft to provide shaft protection. Do
not clamp the vise grips too tightly to the wiper arm shaft. Failure to comply with these
cautions could result in damage to the shaft.
7.
Wrap a clean wiping rag around the blade end of the wiper motor shaft (9) and lightly clamp a pair of vise grips to the
shaft end. This will allow judging of wiper shaft position.
8.
Turn ON the wiper motor assembly (14) and observe the arc of the vise grips. Turn OFF the wiper motor assembly when
the vise grips have reached the end of their arc. It may take several tries to stop the vise grips at the end of their arc.
9.
Install the wiper arm as described in the Installation--Wiper Arm procedure in this work package.
