I talk about and show the timing wedges in this video... particurlarly at the 1:30~ish mark...

also for a CM871 .. its always a #4 wedge for the injector cam. Make sure your using the right wedge. .. and make sure your wedge is up to proper spec. vs. an oem wedge.





Here is a close-up from the video at 7:26. This is the OEM tool from cummins, and a brand new OEM head ...

As the picture shows, the OEM wedge has a line scribed on it (from factory) that is even with the top of the head when its sitting in the right place. Also, the back of the wedge is also rounded and fits snug into the rounded cut-out on the head without a gap.

Also note how much deeper mine is sitting compared to yours....


is yours an OEM head?.

If not then it may not have been machined quite right.. also.. you should never use a non-oem head on an ISX. The quality is s$it, and it will usually only last for only a few years at most, and need replacing for one reason or another.. costing you big-time!.

Follow the link I mentioned above and do everything 100% as mentioned if you want something built properly. Otherwise it is at the peril of longevity.
