Re: Changing alternator belt in 1977 Delta 88
On the older cars, the alternator was attached by two mounting bolts.
The long bolt goes through the alternator and is held on by a hex nut.
The short bolt goes through a slotted curved piece into the alternator
and is used for adjusting tension on the belt.
Depending on the location of the alternator, it may require you to work
from the top of the engine or in some cases from under the car.
Determine if any other belt is blocking the alternator belt. If so, this belt will have to be removed first to access the alternator belt.
Use a little
penetrating fluid (e.g. PB Blaster) on the threads of both bolts and let it soak in to loosen up any corrosion. Using
two wrenches/sockets(one to hold and one to loosen), loosen the long
pivot mounting bolt; but do not remove. Then use a wrench or socket to
loosen the short bolt and push the alternator towards the engine to
allow the belt to be removed.
Installation is the reverse. You will have to lift the alternator up and outward to tighten the belt prior to tightening the short bolt. Then tighten the long bolt. Check tension by pressing down on the midpoint along the longest span between pulleys. Belt should not deflect more than 1/2 to 3/4 inch. If it does, loosen the two bolts and re-tension (you may need a pry bar for adjustment). Some setups use an idler pulley for adjusting tension.

Could be the alternator bearings, there are two of them, one inside in the front, one inside in the back. You can sometimes tell by using a mechanic's stethoscope, which is a long screwdriver or an long thin stick. Place one end on the alternator (when the motor is running) and the other end in your good ear. A bad bearing will scream at you. The other think more likely is a worn out belt. They make an awful noise sometime when the rubber gets hard. The can chatter, squawk, and other sounds mimicking the alternator. Also, be sure to check the belt for cracks on the inside surface. Changing the belt is cheaper that replacing the alternator, if you'd care to try the least expensive fix first, and you still aren't sure.
Air pump/Smog pump and Compressor go on first, on the shaft.
Power steering goes on next
Altenator is the last one.
After market pulleys and the above mentioned parts may change this order..

YOU WILL SEE A PULLY THAT LOOKS LIKE IT ON AN ARM PUT A SOCKET IN THE NUT AND EATHER PULL FOR WARD OR PULL BACK AND IT WILL ROTATE TO ALLOW THE BELT TO COME OFF. THEN REMOVE ALTERNATOR MAKESURE TO TAKE POSITIVE CABLE OFF BATTERY SO YOU DONT SHORT CERCATE THE SYSTEM.
Sounds like you are in the right area. There is a good chance that the belt is OK and just needs tightening. I'm not familiar with this model but I'm presuming that there is adjustment available (Usually the pump is mounted on bolts that you can loosen and then lever the pump out a little to tighten the belt.
That should cure the issue. Failing that, or if you have already tightened the belt, time for a new one I imagine.
if the old belt is still on, its quicker if you just trace how the belt goes around the different pullies on a piece of paper, or take a digital photo of the belt. that way you how to install the new one.
If your pan is dented or crushed your selector paw in the trans has nowhere to go, this is super easy to fix - dont try to fix the pan, you can get a new one for cheap - or a used one if the salvage yard has not crushed everything with that trans, go to the parts store and get a new one maybe $20-30, it is very straight forward - make sure you get a new gasket ((or)) what I do is use permatex rtv black and put a nice even bead around the pan - smooth it out with your finger to about 1/16" thick and let it set up for about 1/2 an hour or till a little tacky put all your bolts in finger tight and retorque aroun the pan every other bolt until they are all tight (check torque specs and definatly use a torque wrench) and might as well change the filter since you are there (very easy) use hurst hot shift fluid or B&M trick shift for replacement fluid
