Do not perform any procedure in the Special Instruction until you have read the information and you understand the information.This Special Instruction describes the proper assembly procedure for the 5N-3765 Flexible Coupling Gp .Note: The sequence of assembly may be modified for the field rework procedure.Assembly Procedure
Illustration 1 g01332640
5N-3765 Flexible Coupling Gp (1) 0S-1589 Bolt (2) 4D-3704 Hard Washer (3) 9H-0846 O-Ring Seal (4) 1A-8537 Bolt (5) 5N-3274 Plate (6) 3N-6666 Drive Coupling (7) 5N-3272 Rubber Coupling Boot (8) 5N-3284 Outer Coupling
Use 5N-5561 Silicone Lubricant (9) in order to lubricate all surfaces that will contact O-Ring seals (3) and boot (7). Do not allow lubricant on plate (5) .
Illustration 2 g01332184
(8) 5N-3284 Outer Coupling (9) 5N-5561 Silicone Lubricant
Illustration 3 g01332205
(6) 3N-6666 Drive Coupling (9) 5N-5561 Silicone Lubricant
Center drive coupling (6) inside outer coupling (8). Use a suitable lifting device in order to safely install the drive coupling. The drive coupling weighs approximately 39 kg (86 lb).
Illustration 4 g01332223
(6) 3N-6666 Drive Coupling (7) 5N-3272 Rubber Coupling Boot (8) 5N-3284 Outer Coupling
Install three boots (7) between drive coupling (6) and outer coupling (8) .
Illustration 5 g01332233
Fill the cavities between the couplings and the boots with the remaining silicone lubricant.
Illustration 6 g01332245
(3) 9H-0846 O-Ring Seal
Install two O-Ring seals (3) in outer coupling (8). One seal is installed on each side of the outer coupling.
Illustration 7 g01332254
(2) 4D-3704 Hard Washers (4) 1A-8537 Bolts (5) 5N-3274 Plate
Install plate (5) onto outer coupling (8). Use 12 bolts (4) and 12 hard washers (2) in order to fasten the plate to the coupling.
Illustration 8 g01332286
Install the coupling assembly onto the cavity of the flywheel. Use a suitable lifting device in order to install the coupling assembly. The coupling assembly weighs approximately 113 kg (250 lb). Use 12 bolts (1) and 12 hard washers (2) in order to fasten the coupling assembly to the flywheel.
Install drive coupling (6) to the hub of the generator.
