today he went to fit a new belt and had a look at the pulley and nothing was wrong with it

but when undoing the altenator he took out two bolts and the thing just fell off

there is no third ajuster bolt and no hole for one????????
so has anyone breaking got a bracket and ajuster assembly for a 4th BB4 H22a? and he may need an altenator as well

pm's to me please as his internet is offline. cheers
