The pulley in question has three nuts or bolts and to get them loose, I need to wedge the pully, that being done, there is a big bolt going through the bracket that I will access when the air pump pulley is removed. My question is once this bizarre bracket is removed and I have replaced the water pump, how do I keep these units from falling off befor I can replace all the nuts and Bolts?
