I have just changed my stock lower pulley and in the process of removing the actual pulley a washer fell out from between the crank pulley and lower blower pulley. My question is should there be a bolt through the center of the crank pulley to hold it on,because there is not one on mine. Firstly Seems odd that there was a loose washer to start with? nad secondly if there is supposed to be a bolt there what size is it? Any help would be greatly appreciated, as I don't want to test drive my truck until I know it is safe.

First I have to know what type of new pulley are you using? If it has 3 allen head bolst that go with it, then no, you don't need a center bolt...

I am just using an interchangeable pulley and I know there is 3 bolts to tighten that up. The question is what holds the other inner pulley (the one that drives the alternator etc) onto the crank, because it appears to have a center bolt missing.

 

YES, there should definately be a bolt holding your harmonic balancer onto the crankshaft!

that bolt uses a fairly large (thick) washer behind it, that may be what fell out?

 

Thanks 'superfords' Does anyone know the size of the bolt I should use as it is definatley missing. Could the pulley come off??

 

Sorry, I miss understood you, I thought you were asking if there needs to be a bolt in the middle of this pulley...

Thats okay. The pulley in the picture is the exact one I have. You do not know the size of the bolt do you? Is it a bolt I could get from a local auto shop?

 

I don't know the size of the bolt, sorry, but I'll look in my manuals...where did it fall out? Could you not find it?

It was never there. The only thing that fell out was the loose washer. Really confused!!!!!

 

Can you get under there and get a picture for us to look at? Might make it easier for us to get a grasp on what'd going on...

 

I've got something that might help you, gimme your email adress so I can send it to you...
