and

remove

the

input

orbital

motor.

16.

Place

the

new

input

orbital

motor

in

position

on

the

main

Make

sure

the

power

cable

is

oriented

to

the

right

side

of

the

new

17.

Guide

the

motor

cable

through

the

hole

in

the

main

plate.

18.

Insert

the

four

motor

wires

into

the

white

Molex

connector.

Be

sure

to

insert

the

wires

in

the

same

order

(and

orientation)

as

shown

in

Figure

orbital

motor

shaft

has

one

flat

side.

Turn

the

shaft

until

the

flat

edge

faces

the
