harmonic balancer on Liberty diesel

I replaced my damper with a new one for a Duramax 2.8L. It is not a direct bolt on. I made a steel adapter to allow the Duramax damper to bolt on to the 2.8L CRD crank. It has been working great and if the rubber ever dies, I can just buy another from the Chevy dealer being they are supporting that engine. It looks factory and uses the stock belt and no other changes needed. It had been on there for about two years now and was around $70 bucks for a brand new one.

I am sure many on here would like to see more details, even a photo or 2 would be good.
Was it just a sleave, or did the bolt holes need to be changed?

Got any drawings of the adaptor you can share?

It's a machined plate just under 1/2" thick. I have pictures of it from start to finish, just have to find them and post them. I made it on a 8"X16" lathe and a mill, it is actually quite a simple piece, just very precisely made, picture a small version of a wheel adapter. I knew the 2.8 Duramax was just the newer version of our 2.8L CRDs and took a chance and ordered in a balancer, timing belt sprocket and new damper bolts for the Duramax 2.8L. You can't use the timing belt sprocket for the Duramax, they changed the width of the timing belt, and if I remember right, won't fit on the crankshaft snout, it's too loose, so you use the original timing belt sprocket for our 2.8 CRD. The bolt circles on the dampers are also different diameters, which actually works great for making the adapter work. The outer diameter where the belt rides is the same so it uses the factory serpentine belt and nothing has to be changed to use it.

Our brains trust (wwdiesel) is probably following this with interest.
I suspect the Duramax is like a RA428. They are used in the KK & Dodge Nitro.
With a little luck, there will soon be adapters on the market.
Maybe the trick will be to have a damper with adapter attached.

I opened a Google photo account trying to post pictures, but can't seem to get them to show up here. I can post the address as a hyperlink so the adapter can be seen.

Unfortunately, none of your links work! :cry:

All three links you posted gave the same error. Google says it's not found!

Well, crap. The links worked when I previewed them, I will try what you showed.

When I preview, I still see no picture, just the word "Image". On Google Photo, I clicked on "Share" and "Create a link". I copied the link and pasted it between the brackets after clicking on [img], the preview showed no picture just the word "Image", so I tried creating a hyperlink. I even tried dropping the "s" off of "https:", but it doesn't seem to work so I put it back. Hopefully the links from "Create a link" will work if the pictures won't show up. I tried these links, and they work, but the last links worked for me too.

Your example "[url>=https://web address "link" of shared picture<[/img][/url]" didn't work either, I tried it on the last picture. I must be doing something wrong, I just don't what.

Why does it always say that my post has to be approved before it can be posted? Is this because I haven't posted enough yet, or does it do that for everybody?

WWDiesel · **Posted:** Sun Jul 16, 2023 11:34 am

The problem is; Google links to the photos are not being shared as pictures, i.e. jpeg, png, tiff, pdf, gif, etc...
I cleaned up your links to the photos which will work by clicking on the links, they just will not show up as pictures in your post, only hot links.

I will upload the front view one of the pictures to my photo sharing provider, (https://postimg.cc) stored as a "jpeg" and post it so you can see it does work. See below!

As to the approval process, we do this to try and keep out spammers. Once a new member has shown to be legit, posts approval is not required.
I will update your status.

Okay, thanks to WWDiesel, I can now actually post the pictures of the adapter.

The Duramax 2.8L timing belt sprocket is on the left, our 2.8L CRD timing belt sprocket is on the right, notice the difference of the bolt circles. Also notice the center of the 2.8L CRD timing belt sprocket on the right, this bump out is what centers the damper. The Duramax 2.8L damper centers itself around the outside of the Duramax 2.8L timing belt sprocket. The centering of the damper at these two points with the adapter is crucial to make sure there is no runout and therefore no wobble.

Our 2.8L CRD timing belt sprocket is on the left this time, the Duramax 2.8L timing belt sprocket is on the right.

The Duramax 2.8L damper is on top of our 2.8L CRD damper in this pic.

This is a pic of my adapter mounted to our 2.8L CRD timing belt sprocket.

This is a pic of my adapter mounted to the new Duramax 2.8L damper, notice the new Duramax 2.8L mounting bolts do not stick thru the adapter and interfere with the fit.

This is a front pic of the new Duramax 2.8L damper bolted to my adapter.

I made this adapter in December of 2020 when I replaced the timing belt, water pump, etc. The damper runs true and uses the factory serpentine belt with no other changes needed.

Thanks again to WWDiesel for showing me how to post pictures and lifting the approval process of being able to post, I would have shared earlier, but with having to wait for approval on posting, I just kept putting it off.

I wish I could make some of them, but unfortunately I do not possess the necessary equipment to produce the adaptor he made. It requires a metal lathe, a milling machine along with precise drilling equipment to produce the adaptor with its precise fitment requirements.
Hopefully or maybe Rattlin' KJ will produce some of them and offer them to the Jeep CRD community. :POPCORN:

If Rattlin' KJ is willing to provide me with his design, I can have these manufactured for those interested. I can also source the Duramax 2.8L damper and the bolts and whatever else is needed, and offer as a kit.

I truly hope this works out.
There are probably other applications for this.
Good Luck !!!

Hi guys, I have been buried at work and got on here and saw there was some interest in the adapter, I'm going to check on some things and let you know what I find out.
