CAUTION
The Drum Temperature Sensor wiring harness is routed through the Exit Module. Use care
when reinstalling to avoid damaging the sensor.
NOTE: To help seat the Drum properly, steps 2-6 provide an explicit order of placement for
installing the screws to secure the Drum Assembly to the chassis.
1.
Seat the Drum Assembly into the chassis.
2.
Align the screw holes in the left and right sides of the Drum Assembly to the holes in the
chassis sides.
3.
Install 1 screw (metal, T-20) and washer at the rear position on the left side to hold the
Drum Assembly; keep the screw loose.
4.
Install 1 screw (metal, hex-head) and washer at the rear position on the right-side to hold
the Drum Assembly; keep the screw loose.
5.
Align the clevis pins on the Transfix Load Arms with the holes in the mounting ears on the
Drum Assembly. The Transfix Load Arms should point in the opposite direction as the
Drum Thermistor. Position the Cam Followers on the Transfix Load Arms under the
Transfix Cams.
6.
Insert the Clevis Pins through the clevis and the mounting ears on the Drum Assembly
(insert the pins from the outside). Check that the O-ring on each Clevis Pin is inside the
chassis.

both sides, second bottom screws on both sides, and third front screws on both sides.

Seat the Exit Module in the chassis by first engaging the 2 front locating pins, and then
the rear locating pins. Connect the Drum Temperature Sensor wiring harness.
