adjusting scavenge belt

[Bicyclops]

May seem like a stupid question but how do you adjust the belt tension on the aviaid scavenge pump? Mine is mounted on an adapter plate bolted right to the alternator bracket. I'm using the provided Jones pulley and a 4 rib belt. There aren't any slotted holes or anything like that I can see.
