ARMY  TM  5-6675-238-14 MARINE CORPS TM 08839A-14/1 8-34. Capacitor C1 or C2 Removal and Replacement. See figure 8-10, sheet 2, and remove and replace capaci- tor C1 (111) as follows: a. Removal. (1)  Remove  two  screws  (112)  and  lockwashers (113) securing two terminal lugs (114) to ca- pacitor  Cl  (111)  terminals;  tag  and  remove terminal  lugs. (2) Loosen four screws (121) securing clamp (110) around  capacitor  C1;  remove  capacitor  C1 from  clamp. b. Replacement. (1)  Install  capacitor  Cl  (111)  in  clamp  (110). (2)  Tighten  four  screws  (121)  to  secure  clamp around  capacitor  CL (3)  Secure  two  terminal  lugs  (114)  to  capacitor Cl terminals with two screws (112) and lock- washers (113). Orange wire connects to posi- tive terminal of capacitor C1. 8-35. Filter FL1 or FL2 Removal and Replacement. See figure 8-10, sheet 2, and remove and replace filter FL2 (52) as follows: a. Removal. (1) (2) (3) Remove two screws (47, figure 8-10, sheet 1) and washers (46) securing cover (45) on rear of motor B3 (17). Carefully hold red and black motor B3 input leads while pushing cover back from motor B3.  This  compresses  the  braided  shielding slightly  and  provides  extra  lead  length. Carefully slide sleeving on each wire toward rear cover for access to-solder connection. Tag and unsolder wires from motor B3. NOTE The  following  two  steps  apply  only  to filter  FL2. (4)  Remove  photocell  amplifier  A1  (57,  figure 8-10,  sheet  2)  and  pulse  rate  generator  and logic  A2  (58). (5) Remove three nuts (103), washers (102), and lockwashers (101), and two screws (29, figure 8-10, sheet 1), nuts (20), lockwashers (21), and washers (22) securing frame to front panel and card cage. Move frame aside to gain access to filter FL2 (52, figure 8-10, sheet 2) hardware. NOTE The following step applies only to filter FL1. (6) Remove servo amplifier A6 (63) to gain access to  filter  FL1  (64)  hardware. (7) Remove two nuts (55), lockwashers (54), wash- ers (53), and one terminal lug (56) securing filter  FL2  (52)  to  front  panel;  remove  filter FL2. b. Replacement. (1) Secure filter FL2 (52) to front panel with two washers (53), lockwashers (54), nuts (55), and one terminal lug (56). (2) Place sleeving on wires that connect to motor B3 (17, figure 8-10, sheet 1). (3) Solder wires to terminals on rear of motor B3. Slide  sleeving  over  solder  connections. (4)  Secure  cover  (45)  to  rear  of  motor  B3  with two screws (47) and washers (46). NOTE The following step applies only to filter FL1. (5) Replace servo amplifier A6 (63, figure 8-10, NOTE The  following  two  steps  apply  only  to filter  FL2. (6)  Secure  frame  to  front  panel  and  card  cage with two screws (29, figure 8-10, sheet 1), nuts (20), lockwashers  (21),  and  washers  (22),  and three nuts (103, figure 8-10, sheet 2), washers (102), and lockwashers (101). (7) Replace photocell amplifier A1 (57) and pulse rate  generator  and  logic  A2  (58). 8-36. Terminal Board TB1 Removal and Replacement. See figure 8-10, sheet 2, and remove and replace termi- nal board TB1 (87) as follows: a. Removal. (1)  Tag  and  unsolder  wires  from  terminal  board (2) Remove two screws (93), lockwasher (94) and washer (95) securing terminal board TB1 (87) and  insulator  (86)  to  chassis;  remove  terminal board  and  insulator. b. Replacement. (1) Secure terminal board TB1 (87) and insulator (86)  to  chassis  with  two  screws  (93),  lockwash- ers (94) and washers (95). 8-103
