Fan belt comes off , crank pulley ? 1974 CJ5

[garya1974cj5]

The other evening I hear a slight squeal sound and smell of rubber, followed by a slight antifreeze smell. I was only a mile from the house . I pull in the shop and raise the hood. The belt is hanging loose. Water pump and alternator look okay.

The crankshaft pulley is not v shaped like other belt guides and looks rubber.
I reach in and the crankshaft pulley is covered by a flat rubber belt , I remove it and it looks like a fan belt that would be about 4 inches in diameter and was on the crank. Now the crankshaft pulley is bare metal and the rubber belt that was broken is not there.

Question is : Does this model have a rubber belt guide on the crank pulley , when I google pictures of Jeep crankshaft pulley nothing but metal pulleys show up.

My motor is the AMC 232 i6 I 6 .




Its not uploading my photos for some reason .

I may need help figuring this one out I thought all fan belt guides were metal.

I can post pictures shortly.

That Vibration Dampner is toast..............no good anymore ....no way to fix.

When they are built that rubber portion is squeezed under immense pressure and then the outer shell is slipped over.........they are designed to calm crankshaft harmonics.

They get old the rubber gets hard or sometimes and oil leak will attack the rubber and then loosen it up.

Go on line and find a new one.
