Help Needed

I am at a loss. The pulley closest to the engine on the crankshaft pulley is rattling bad and is super loose. I have pics and videos to show which one I'm talking about. Any help finding the part to help me fix it would be greatly appreciated.

 

Gonna need the harmonic balancer

 

Does it come as a unit of all 3 or just the single one in the back? I'm having trouble finding anything online rn

 

I’m pretty sure it’s the whole assembly

 

Harmonic balancer

It's even worse on GM motors

 

In any case you need to remove the whole assembly to inspect just what your dealing with.

See just what you need and proceed from there.

 

The very back pulley is the harmonic balancer.....
its center mounted in rubber and wears out.....

the outer two just bolt to it....4 bolts inside the pulleys...

I went and just replaced mine with a doorman brand one from O-Reilys.....

You'll have to inspect your timing cover and make sure it didnt damage/crack it....
That harmonic balancer slides into it....its tough to see the damage on inside...
inspect all that carefully.......and watch for oil leaking for a while after replacing.


Removing that giant bolt holding the HB is usually a challenge to get off.....
but when the HB is shot.....it usually comes off easier....

You are suppose to replace that giant bolt too....not suppose to be reused....

The 4 bangers are fairly simple to work on......no having to take half the engine off to get to something.....

 

Had to take this off when I replaced my leaking timing cover... let me know if you want any info on the whole process. It really isn't all that bad and there's a few things you might as well also do while in there.

 

I just did mine, this is where I bought the replacement:

They ship pretty fast too. You'll need one of these to tighten:

I just used a breaker bar leaning against the frame and tapped the starter to break the bolt loose. You'll need a new main bolt as it's a torque to yield.

 

That tool is great and 100% needed. Recommend getting better bolts to hold it in place. Put a breaker bar in it and rotate the engine until its pushing against the frame then grab your torque wrench and pull as hard as you can. I got to like 188ft/lbs figured it was close enough. Felt like I was about to blow a gasket... and not on the truck.
