Note
Do not reuse the generator pulley cap.
REMOVE GENERATOR PULLEY
Secure the generator drive end frame assembly and generator coil assembly in a vise between aluminum plates.
*1 | Generator Rotor Shaft |
Install SST (A) and (B) to the generator pulley as shown in the illustration.
Note
Securely attach SST to the generator pulley and generator rotor shaft.
*a | Hold |
Turn |
Using a wrench to hold SST (A), turn SST (B) counterclockwise to loosen the generator pulley.
Note
Check that the generator drive end frame assembly and generator coil assembly are secured in the vise tightly.
Hold SST (A) tightly during the operation.
Remove SST (A) and (B) from the generator pulley.
Remove the generator pulley from the generator rotor shaft.
Remove the generator drive end frame assembly and generator coil assembly from the vise.
REMOVE GENERATOR REAR END COVER
Place the generator assembly on the generator pulley.
Remove the 3 bolts and generator rear end cover from the generator coil assembly.
REMOVE TERMINAL INSULATOR
Remove the terminal insulator from the generator coil assembly.
REMOVE GENERATOR BRUSH HOLDER ASSEMBLY
Remove the 2 screws and generator brush holder assembly from the generator coil assembly.
REMOVE GENERATOR COIL ASSEMBLY
Remove the 4 through bolts from the generator drive end frame assembly.
*a | Hold |
Turn |
Using SST, remove the generator coil assembly.
REMOVE GENERATOR BEARING COVER PACKING
*1 | Generator Bearing Cover Packing |
Remove the generator bearing cover packing from the generator coil assembly.
Note
If the generator bearing cover packing breaks, remove all broken pieces.
Tech Tips
The generator bearing cover packing may be installed on the generator rotor assembly.
REMOVE GENERATOR ROTOR ASSEMBLY
*1 | Generator Rotor Assembly |
Remove the generator rotor assembly.
Note
Do not drop the generator rotor assembly.
INSPECT GENERATOR DRIVE END FRAME BEARING
Check that the generator drive end frame bearing is not rough or worn and that it rotates smoothly.
If the generator drive end frame bearing does not rotate smoothly, replace the generator drive end frame bearing.
REMOVE RETAINER PLATE
