TM 11-5895-1179-13 E132-EA-OMP-010/E106 KY883 TO 31S1-2GGSC-161

Remove the four nuts and washers which attach the inductor to the bottom panel assembly mounting studs

(figure 5-5). Remove the power inductor A7L1.

Set the new power inductor in place on the mounting studs and install the four nuts and washers removed in

step c.

Connect the replacement inductor leads to A7TB2-15 and -17 (figure 5-2). Install the terminal board cover

removed in step h. Use tiedown straps to replace those removed in step B.

Install the four plug-in-circuit card assemblies (paragraph 4-7) and the chassis cover (paragraph 5-6).

Close and secure the front panel assembly.

5-22.

Removal and Replacement of Capacitor A7C2

Remove the chassis cover and the four plug-in-circuit card assemblies as described in paragraphs 5-6 and

4-7, respectively.

Unsolder and remove A7C2 from A7E3 and A7E4 (figure 5-5) using standard heat sinking techniques.

Remove the capacitor by breaking the adhesive bond between the capacitor and the mounting plate.

Apply adhesive 465-11, item 1, App. E to the replacement capacitor and install with the positive lead to

A7E3.

Solder in the replacement capacitor using standard heat sinking techniques.

Install the four plug-in-circuit card assemblies (paragraph 4-7) and the chassis cover (paragraph 5-6). 9.

Close and secure the front panel assembly.

5-23.

Removal and Replacement of Front Panel Assembly A6 and Hinge Pin

Release the four front panel assembly fasteners (figure 2-1) and lower the front panel assembly. B.

Disconnect the interconnect cable assembly A8A3 from the connector A6AlJ1 on the display and control

circuit card assembly (figure 5-3). Note the dressing of A8A3 and the keying of the interconnect cable (figure

5-5) for replacement purposes. Disconnect the electronic signal connector assembly A8A2 (figures 5-3 and

5-5) from A6A1J2. Remove the fuseholder assembly A6A3 (paragraph 5-8) and ON/OFF switch assembly

A6A4 (paragraph 5-9) from the front panel assembly.

Remove the restraint assembly (paragraph 5-20). v.

Remove the hinge pin (figure 5-3) from right to left with a drive pin punch. Remove the front panel assembly.

Place the replacement front panel assembly in proper position against the chassis and install the hinge pin.
