Removal (Fig. 24)
1. Park vehicle on a level surface, stop engine, set
parking brake and remove key from the ignition switch.
2. Raise cargo box and secure with prop rod to gain ac-
cess to the starter/generator.
NOTE: Place all fasteners back onto starter/generator
terminals after disconnecting wires to prevent loss of
fasteners.
3. Label all wires on the starter/generator for assembly
purposes. Disconnect all wires from the starter/genera-
tor.
4. Loosen fasteners that secure starter/generator to
engine tray assembly.
5. Pivot starter/generator and remove drive belt from
the pulley.
6. Support starter/generator to prevent it from shifting
or falling.
7. Remove lock nut (item 2) and carriage bolt (item 10)
from upper starter/generator flange and bracket on en-
gine tray. Remove flange nut (item 13) and pivot bolt
(item 11) from starter/generator and engine tray.
8. Remove starter/generator from the vehicle.
9. If necessary, remove pulley from the starter/genera-
tor shaft:
A. Remove nut and spring washer from the shaft.
Use appropriate puller to remove pulley from the
shaft.
B. Remove woodruff key from the shaft.
NOTE: Vehicles with serial number below 311000000
were produced with a Valeo brand starter/generator.
Vehicles with serial number above 311000000 were pro-
duced with an Advanced Motors and Drives brand
starter/generator. If a Valeo starter/generator has been
replaced for some reason, the replacement starter/gen-
erator may have been an Advanced Motors and Drives
component. Starter/generators have an identification
tag on them which identifies the brand. Service informa-
tion for these two (2) types of starter/generators is in-
cluded in this chapter. Make sure to use the correct
information for the component that is being serviced.

shaft:
A. Position woodruff key to the shaft. Slide pulley
onto the shaft with the larger diameter pulley hub
installed toward starter/generator.
