When I changed mine out last year I used ratchet straps and ratcheted that baby right up and in. I didn't have a floor jack or it would have been easier!!! I have to go with Clifford on this one except I'm not ever gonna try and actually lift one of those puppies by hand. There's no way I could lift that into place without some sort of mechanical help.
The nagging question remains though.... just how many of us have replaced them only to find it was dirty ground connections.
I know I count for one.

Well on an older MCI (and others) a ratchet strap or floor jack work great! But on some (alot!) of newer buses with ECMs there just ain't room to get into it without tangling the straps in the wires. And some (Setra's) ya better have a floor jack that goes up, side ways, back up and to the other side! (none of mine do that! 
)
Not a bad ground, (as that is one thing I always check)
but a broken wire on the back of the alternator yes! (happened to be the problem on the bus I worked on last year on Super Bowl Sunday! But the owner insisted
"it has to be the starter, I just put in new batteries last week!" Who am I to argue with the customer paying $125 /hr for a service call on Super Bowl Sunday for what could have waited until Monday at $75 /hr? I put the starter on and still had to jump the solenoid to start it! Then he say's
"Well I don't really have to have it the next few days, you go on and take it back to yer shop and fix it now that you got it started!")
