There are a couple different fixes for it. If you go to a website like turbodieselregister.com and do a search you will find a lot of threads on the fixes. As I am sure just doing a search on google or the like will also provide answers. The TDR at one time had regional jigs that you could request and the local keeper of the jig would send it out to you for the cost of shipping and then you returned it or sent it the next person on the list. Though the jig method has been pretty much superseded by the tab method and I would suspect that by now the jigs are long gone. Using the jig you could do the job in about 90 minutes or so and required a lot less tear down to get to it you essentially just screwed the kdp through the case.
THANKS BarryG20 for your response to my question. After replacing the diesel fuel lift pump a year ago, I don't need another $7,000 repair bill and this "dowel pin" issue on the 5.9 12v sounds like the unlucky folks could be spending a load to get their engine repaired.
