Eating timing belts

<< < (2/5) > >>

Hrmf, bummer that there are bad tensioners out there. I got mine from IDParts. At ~$50 I'm not thrilled to swap it out again but beats a ruined engine.

Here's a short slow motion of the belts, it looks like it starts to move on the intermediate pulley. Cam and IP pulleys look okay to me.

Is the initial picture in this thread where the belt normally runs on the injection pump?

Yup. There is a short video of the IP in my last post as well if you didn't see it.

I missed the cam and injection pump videos.  I have never seen a belt get worn on the side like that unless it was walking off the injection pump.  What is the dust that is on the backing plate by the injection pump sprocket?  The tracking all looks fine.  Any chance one of the outer covers  or any other part is touching the timing belt when those parts are installed?   

I watched the vids and I think I would be checking the belt tensioner bolt.  As the belt comes up from the crank it appears to rub on the tensioner and that is what we see as wear on the front of the IP.  I also hate to say it but you might need to check the crank pulley as well. 

A little wobble might be doing the belt in. 

First check the bolt in the block on the tensioner.  It may just be a tad loose.
