Install two 1/2"-13 NC forcing screws in the bridge rectifier. Remove bridge rectifier (4) and exciter armature (6) as a unit from the generator. The weight of the unit is 27 kg (60 lb.). 5. If necessary, remove key (8) from shaft (7).6. If key (8) was removed, install key (8) on shaft (7).7. Install two 5/16"-18 NC guide bolts in the end of shaft (7). Put bridge rectifier (4) and exciter armature (6) as a unit in position on the guide bolts. Make sure the groove (slot) in the exciter armature is in alignment with key (8) and push bridge rectifier (4) and exciter armature (6) on the end of the shaft.8. Apply loctite on bolt (2) threads. Remove the guide bolts and install spacer (5) and bolts (2) to hold the bridge rectifier and exciter armature in position.9. Connect wires (3) to the bridge rectifier.10. Install cowl cover (1) on the cowl assembly.Disassemble Bridge Rectifier And Exciter Armature
start by:a) remove bridge rectifier and exciter armature Steps 1 through 6 can be done without the removal of the bridge rectifier and exciter armature. 1. Put identification marks on wires (1) for correct installation and disconnect wires (1) from varistor assemblies (2).2. Remove nuts (3) to remove varistor assemblies (2) from the bridge rectifier yoke. 3. Put identification marks on wires (5) for correct installation. Disconnect wires (5) from the terminal strips on the heat sink assemblies.4. Remove bolts (7) and the washers to remove positive heat sink assembly (4) and negative heat sink assembly (6) from the bridge rectifier yoke. 5. Remove clamp (9) and remove suppression resistor (8) from the positive heat sink assembly. 6. Remove nuts (10) and remove rectifying diodes (11) from both of the heat sink assemblies. 7. Remove string (12) that holds the wires against bridge rectifier yoke (13). 8. Remove bolts (14) and remove the bridge rectifier yoke from exciter armature (15).Assemble Bridge Rectifier And Exciter Armature
