the brackets. Use caution not to damage trim indicator wire (2).

bushing and unwrap the right cable (8).

1 Wrap the right trim cable on the trim drum by inserting the swaged ball of the cable in
the slot provided in the side (right side) of the drum that mates with the control
wheel, and looking at this side, wrap the drum with three wraps of the cable in a
clockwise direction.
2 Attach the control wheel to the cable drum by aligning the long lug of the drum with
the long slot of the wheel and pushing the two pieces together.
3
Wrap the left trim cable on the drum by inserting the swaged ball of the cable in the
slot provided in the flanged side (left side) of the drum and looking at this side, wrap
