A variety of alternators were used:
The alternator needs no lubrication or adjustments except for drive belt tension.
Certain safety precautions should be observed concerning the alternator:
- Do not polarize the unit.
- Do not short across or ground any of the terminals.
- Never operate the unit with the output terminal disconnected.
- Make sure that the battery is installed with the correct polarity.
- When connecting a booster battery or a charger, always connect positive terminal to positive terminal and negative terminal to negative terminal.
- Disconnect the battery ground cable when working on any electrical equipment.
- If any electric welding is done on the car, disconnect the alternator completely.
REMOVAL & INSTALLATION
See Figures 1 through 10
- Disconnect the battery cables.
Always disconnect the ground cable first, and connect it last, and then you needn't fear sparks.
- Remove the adjusting bolt.
- Take off the drive belt.
- Disconnect the alternator wires or wiring plug.
- Remove the mounting bolts and the alternator.
- Reverse the procedure for installation.
- Adjust the drive belt.
BELT TENSION ADJUSTMENT
The alternator drive belt, or any engine V-belt, is correctly tensioned when the longest span of belt between pulleys can be depressed about 1 / 2 " (12.7mm) in the middle by moderate thumb pressure. To adjust, loosen the slotted adjusting bracket bolt. If the alternator hinge bolt(s) is very tight, it may be necessary to loosen it slightly to more the alternator. V8 engines have a hole in the alternator bracket, so that you can insert a big screwdriver and pry out on the alternator. Some V8s have a square hole into which you can insert a 1 / 2 " square socket drive. The best way is to pull the alternator out by hand to avoid overtightening.
