The fan clutch will not fit our water pumps but... If you have a bus or dump truck then it will fit that pump. Those bus and big heavy trucks use a differant pump. It has the four bolts that connect it to the pump and we have the one large threaded nut for our trucks. I wonder if there is any advantage in thrying the bus pump and fan clutch along with the fan....
I'm sure the fan is way too big but could it be cut down and rebalanced....
