Need to pull alternator without use of tensioner pulley

I'm trying to pull my alternator off for replacement on my '99 7.3. When I was pulling up on the tensioner pulley to remove belt, the hole for the 1/2 drive cracked. Is there any way to pull the serpentine without using the tensioner pulley?

There should be a lock on the bottom of the tensioner. If you pull on the belt in a long straight section far enough to engage the lock then you can do it without using a ratchet on the tensioner.

does your tensioner have a hex head or torx head on the tensioner pulley itself? if it has a hex, you can put a wrench on it and use that to pull it out of the way. If it has a torx, you can try it, but it's pretty difficult to get a good bite on it, the torz likes to slip out lol. If it were me, i'd cut the belt and replace the tensioner.

You could always cut the belt.

Sorry for the delay. I was able to take it off by putting all my weight on the alternator while I loosened the bolts. I had a long screwdriver going through next to the alternator which was taking some tension off. I then slowly tilted the alternator down and slid the belt off. I reinstalled the new pulley the same way. Eventually, I'll probably take ianstew's advice and replace the tensioner pulley. Thanks for all the suggestions.
BTW, while I was able to install the pulley, it doesn't seem to be charging. I'll be creating a separate post for that issue.
