TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 CHAPTER 11 MAINTENANCE OF GENERATOR AND RECONNECTION ASSEMBLY 11-1.  GENERAL.  The generator is a single-bearing, brushless type with integral exciter.  It is directly driven from the engine through a disc coupling.  The bearing requires no lubricant and can be replaced without removing either the engine or generator.  The excitation system consists of an exciter and voltage regulator.  The excitor has a rotating armature and rotating rectifier.  The reconnection box assembly provides access for reconnecting generator phase windings through current transformers.  Windings of each phase may be connected in series or parallel on buss bars.  Reconnection box also provides a means of converting the generator set from 120/208 volt to 240/416 volt operation. 11-2.  RECONNECTION BOARD AND BUSS BARS REMOVAL AND REPLACEMENT. a. Removal. (1) Remove front panel (12, figure 11-1, sheet 1) by removing screws (1), washers (2 and 3), and hook (4). (2) Remove panel support (13). (3) Disconnect, tag, and remove harness (71) and (73) and power cables (74). (4) Remove buss bars and jumper bars (38 thru (45) by removing their attaching hardware. (5) Remove reconnection board assembly (15, figure 11-1, sheet 2) by removing the 14 screws (16), nuts (19), and washers (17 and 18). b. Replacement. (1) Replace reconnection board assembly (15) by replacing the 14 screws (16), nuts (19), and washers (17 and 18). (2) Replace buss bars and jumper bars (38 thru 45, figure 11-1, sheet 1) by replacing their attaching hardware. (3) Replace harness (71 and 73) and power cables (74). (4) Replace panel support (13). (5) Replace front panel (12) by replacing screws (1), washers (2 and 3), and hook (4). c. Limit Switch. (1) Test.  Using an ohmmeter test limit switch S120 (14, figure 11-1, sheet 2) for continuity.  Switch should have a distinct clicking action when operated from one position to another.  Replace switch if no continuity is indicated. (2) Replacement. (a) Remove limit switch S120 (14) by removing locknut and washer that secures switch to reconnection board (15). (b) Install new switch on reconnection board (100) and secure locknut and washer. 11-3.  CURRENT TRANSFORMER REMOVAL AND REPLACEMENT. a. Removal. (1) Remove reconnection board and buss bars, par.  11-2 a. (2) Remove current transformer assembly (22, figure 11-1, sheet 2) by removing ten screws (20) and washers (21). 11-1
