Here are the pics of my parts truck with the broken bracket (I already posted a pic of the other half) and some pics of my truck with the fan belts on and water pump belt hanging to the side.
There does not appear to be any eccentrics to the fan bracket, the only adjustment is the bolt that moves the fan hub up and down. So the belts must have to be properly mated to reach tension together I think.
I'll try and get belt measurements Tommorrow.
What am I seeing here? Three fan drive belts all the same size. One very short water pump drive belt from the fan hub and one generator drive belt from the water pump. If so you'd adjust the fan belts first then the water pump and then the generator.
Jay says it's a1971 Dodge CNT900.
It also looks like the fan is not directly over the crank. Offset to the left.
