Secure PTM connector end - TB-9-2320-280-35-10102

TB 9-2320-280-35-1

CAUTION

Do not overtighten DCM/PTM interconnect cable. The DCM/PTM

interconnect cable is made of plastic and will break when

overtightened.

27-11. Secure PTM connector end (17) of DCM/PTM interconnect cable (6) to PTM mount assembly (15)

with nut (18).

NOTE

Apply anti-seize compound as required.

27-12. Mount PTM control assembly (31) on PTM control mount bracket assembly (35) with three

screws (36), six washers (32), and three nuts (33). Ensure PTM control assembly handle (30) has

sufficient room to clear steering wheel and standard radio rack (34).

NOTE

Installation of PTM azimuth control cable may take several

attempts before all adjustments are correct.

27-13. Remove bolt (27) and washer (26) from PTM mount assembly (15) and azimuth sector gear

assembly (25).

NOTE

To determine which cable is the azimuth control cable, move PTM

control handle left, right, fore, and aft to see which cable moves.

27-14. Insert azimuth control cable (8) into side of PTM mount assembly (15).

27-15. Install azimuth control cable rubber boot (19) on azimuth control cable (8).

27-16. Install azimuth control cable (8) into clevis (21) of azimuth sector gear (25) until approximately one

thread of shaft (16) is exposed through clevis (21). This is the starting position for aligning azimuth

sector gear assembly (25).

27-17. Tighten azimuth control cable locking nut (20).

27-18. Position azimuth sector gear assembly (25) onto PTM mount assembly (15).

27-19. Insert azimuth control cable (8) into PTM mount assembly cable lock (37).

NOTE

PTM control assembly must be in the center position.

27-20. Ensure that azimuth locking pin hole (22) in azimuth sector gear assembly (25) is aligned with

azimuth lock cable (9) in PTM mount assembly (15). If aligned, proceed to next step. If not aligned,

repeat steps 36-15 through 36-19, adjusting the azimuth sector gear assembly (25) position on the

azimuth control cable (8) until alignment is achieved.

27-21. Secure azimuth sector gear assembly (25) to PTM mount assembly (15) with bolt (27) and washer (26).

27-22. Insert azimuth lock cable (9) through hole (29) into PTM mount assembly (15).

27-23. Install azimuth lock cable rubber boot (23) on azimuth lock cable (9).

27-24. Adjust top and bottom locking/adjuster nuts (24) until locking pin (28) clears azimuth sector

gear assembly (35) by 1/16 in. when PTM control azimuth locking trigger is pulled.

27-25. Ensure azimuth control cable (8), azimuth lock cable (9), and rubber boots (19) and (23) are

installed correctly.
