How do you put back alternator on 88 Nissan hardbody D21?

REMOVAL & INSTALLATION

On some models, the alternator is mounted very low on the engine. On these models, it may be necessary to remove the gravel shield and work from beneath the truck in order to gain access to the alternator.

1. Disconnect the negative battery cable.
2. Remove the alternator pivot bolt. Push the alternator in and remove the drive belt.
3. Pull back the rubber boots and disconnect the wiring from the back of the alternator.
4. Remove the alternator mounting bolt and then withdraw the alternator from its bracket.

To install:
