Maybe there is a belt I just can't see? (Helplessly hoping)
There is roughly 50-60k miles on that engine.
IF I do indeed find the ability to take it out, should I have it rebuilt, put a different unit on? If so, where?
I do NOT want issues with that monster.
Thoughts?

More than likely yours is gear driven.

I don't no where you are located and therefore have no idea if I have a suggestion of who to take it to for you.

But you might want to check out kirksauto.com I have bought many products from them and have been extremely happy.  (sometimes you can buy stuff from them on Ebay cheaper than you can online. & I have also bought brand new Kirk's stuff from other sellers on Ebay that bought it, stocked it and never used it.)

Either way directly or thru Ebay I have never been disappointed with Kirk's products.

Now as far as getting that heavy sucker out. I usually get it all unbolted except the top bolt which I lossen but leave in until I get ready to pull it completely out.
Disconnect connections and oil lines.
Now get a helper. IIRC you have a good source of strong back weak mind labor. (teenage son)
Next get an old belt (man's waist belt) or similar device and put the loop around the alt. grab the other end and pull up on it while removing that last bolt.
One person will need to kneel at the hole guiding the alt. while the other stands and lifts it up and out of the hole.
Be sure to have a large trash bag or something to sit it on and wrap it with for removal from the bus because not only is it big and heavy, but it's most likely going to be NASTY GREASY too!

daddysgirl, there's hope, both of my 1975 MC8's are belt drive.

Back of the engine, furthest from the rear bumper, look thru the street side side door, the belts and the alternator are hanging up in there.

Then, identify the grease gun fitting for the bearing in each end, on both ends of the beast, they go in perpendicular to the shaft, about 3-4 inches long, as they go right into the heart of the thing. Either remove and replace with a traditional Zerk, or find the matching fitting for your grease gun. Either the fitting comes off, or the whole pipe will wind out, doesn't matter. Prime the pipe with grease before re-install.

One of mine has a slick air filter mounted on it, the other just has a metal shield. Put a fresh filter, if it has one.

And the 4 belts were commonly purchased as a matched set, cut from the same stock... MCI $$$$

happy coaching!

I can see the beast (luckily, newly painted and free of road grime) from the curb side door, but nary a belt. The blower motor and associated lines are there. There is also a wide strap looking thing, but it doesn't have belts (That I can see) From the left side, there is some kind of adjustment bar, and the beast bolts up to that, and directly to what looks like the bottom of a tree, for lack of a better descriptor.

Ya know, I'm going to find a picture.

That what looks like the tree trunk is a support that helps hold that heavy alt. in place.
I have seen many times where a mechanic was plain too lazy to put that support back in place which is very hard on the bolts, case and gasket/seals just letting all that weight hang off the bolts.

The wide strap is most likely a ground strap.

Thanks for all the suggestions and the weight.  Being I going to remove both the Alternator and Air Compressor.  Which one should I remove first?  And which should I install first?

BK, thanks for the information and the belt idea.  I going to attempt to borrow a A-Frame that is used to remove engines from boats and a come-a-long

The Eagle Model 20 didn't have a 24 vdc system.  It had a 24 v alternator that feed the 24 volt HVAC fan motors and a few other motors like water pumps for the dash heat.  The alternator was belt driven off the "front" of the engine at the rear of the bus.

Again, thanks for the info and suggestions.
