You first off need to remove the belt. Then you will have access to get the idler off.
So the bolt in the middle of the idler has broken off in the engine?
Is it flush or is it hanging out a little?
That means the bolt in the center of the idler is broken. A new ford idler comes with the bolt in it which is also the shaft.
You will need to remove the bolt/shaft using channel locks or vise grips or abolt out sockets.
no that is NOT what I mean.
There is a shaft made of white metal, like a dowel,
that is pressed into the front of the block.
The pulley bolt is tapped into the center of the shaft.
The shaft is broken off at the block.
The bolt came off with the 1/2 inch piece of the stud, or shaft, or spindle, that snapped off flush with the block.
The stud is white metal set into the cast iron of the block.
I was thinking of making something out of brass.
About 1/2 inch brass rod drill and tap and then foce it into the block.
Other than that I don't know
From this picture it sure looks like its a part of the front cover which is aluminum (white metal)
is that the entire front of the engine?
means the water pump and everythingelse will come off?
i will have to put a magnet on it but it looks cast iron to me.
