Introduction
This Special Instruction provides the Disassembly and Assembly, the Inspection, and the Troubleshooting needed for servicing the flexible couplings for the above C175-16 Locomotive and Petroleum Engines.Note: Do not damage the coupling with tools (wrench, hammer, etc.) during assembly and installation. Do not step on the coupling.Note: Any impacts to the surface of the coupling can lead to damages of the fiber reinforced plastic. These impacts are not necessarily visible from the outside. These impacts may reduce the service life of the coupling.Disassembly and Assembly
Disassembly of the 329-0236 Flexible Coupling Gp , 350-7171 Flexible Coupling Gp , 350-7182 Flexible Coupling Gp , and 396-3847 Flexible Coupling Gp .
Remove the flexible coupling gp guards.
Disconnect the generator from the flexible coupling gp.
Using a suitable lifting device, remove the generator from the engine. The generator weighs approximately 6804 kg (15000 lb).Note: Always refer to the manufacture's identification plate on the generator for the correct weight.

(1) 349-5263 Flywheel As (2) Flexible coupling gp (3) Inner star flange (4) 166-1880 Bolt (5) 199-7107 Spring
Remove two bolts (4) and two springs (5) from flexible coupling gp (2) .Note: The two bolts and springs need to be opposite from one another.
Install two M20 x 2.5 dowels into flywheel (1) where bolts (4) were removed.
Remove the remaining bolts (4) and springs (5) .Note: Approximately 4 L (1 US gal) of oil will drain from the flexible coupling gp when separated from the flywheel.Note: Use the threaded holes on the face of the coupling for lifting.
Using a suitable lifting device, remove flexible coupling gp (2). The flexible coupling gps weigh approximately:
329-0236 Flexible Coupling Gp 102 kg (225 lb)
350-7171 Flexible Coupling Gp 102 kg (225 lb)
350-7182 Flexible Coupling Gp 102 kg (225 lb)
396-3847 Flexible Coupling Gp 102 kg (225 lb)
