Crank Pulley Nut

[SSGRHYMER]

Hey

Thanks Mr Neal

That is what I thought at first. My Crank does fit but slips on the badly worn jaws. Not that i tried to start it ( scared).

That nut is about 38-41 mm not like the spec ones for a Dodge truck. Why would this be considerably smaller.

It looks like one from a Willys Jeep.

 

I have a replacement nut 1 13/16 and lock washer. I want to make it right. 

I hope it works.

Bryan What is the difference in Cars and Truck with pulley and nut?

The cars have a ring of smaller bolts surrounding the nut.  Doesn't change anything except if the middle crank nut is turned a certain way the shoulders are near the surrounding bolts, and you can't get a socket on it til you remove the smaller ones.

Thanks I understand now.

So there is no change in the size of threads (meaning bolt size) when the nut is screwed into the crank. They all should be the same for cars and trucks for Dodge?

Same thread size for all crank bolts unless after around 1955 or later...smaller thread size.
