Then use a fiber or soft metal tubeto tap bearing into place. (See figure 11-16.) Makecertain that pressure is applied only to the bearing innerring.Figure 11-16. Install Bearing on Generator Shaft(b) Press bearing onto shaft until inner ring isagainst bearing shoulder on the shaft.Continue assembly after the bearing has cooled.(c) Using a crane, install endbell (85) and PMGstator and exciter assembly, over generatorshaft.(d)Install screw (80) and washers (81).(e) Install screws and lockwashers (82 and 83)attaching bearing cap (84) to endbell (85).(f)Line up lockwasher (87) and tighten nut (86)to secure bearing.(g) Tighten setscrew (52) in exciter rotor (38).(h) Install PMG rotor (37) with pin (36), scres(35), and washer (34).(i) Replace cover (30) with screws (26 and 28),washers (29), and nuts (27).11-10. DRIVE PLATE ASSEMBLY.a.General. The generator shaft is directlydriven by the engine shaft through the driveplate assembly, figure 11-17. The couplingcompensates for misalignment between thetwo shafts to eliminate injurious stress onthe connection components.b.Replacement.(1) Removal. Remove drive plateassembly (59, figure 11-3) as follows:(a) Remove cover (63) and cover (67)by removing screws (64), washer(66), and nut (65).(b) Remove screws attaching driveplate assembly to engine flywheel.(See figure 11-18.)(c) Loosen setscrew (60) in couplinghub (61).(d) Push drive plate assembly as far aspossible towards the generator fan,in order to gain access to the hubscrews (57).(e) Remove screws (57) bystraightening locking plate (58).Remove drive plate assembly.(2) Replacement. Install drive plate assemblyas follows:(a) Locate drive plate assembly onto hub (61)11-27
