You really dont need to drill and tap you can by a kit to do it or make one your self , its a dowell pin and a tab to put over the dowell pin , cummins has them as well as other places , some guys also hit the out side of the dowell with a punch to swell the metal so the pin cant move as well

The drill and tap KDP setup is not widely used any more. The reason is because of 5 bolts inside the front cover which can come loose and do as much damage as the KDP. What you will need to do is remove the front cover and remove 4 of those bolts clean and loctite them. The last one will need a slightly different procedure do to its location behind the gear that drives the PS/Vac pump. You will need to bend a 10mm wrench to loosen it then clean it and use the weeping locktite and tighten it.

I've seen the damage that just one of these bolts coming loose can do - cam shaft broken in three places and bent push rods. The engine did not sustain any major dammage but I think you can see the need to address these bolts.

Of the 5 bolts, I haven't seen the one hidden behind the gear part of the cam gear coming loose. I use the wrench to tighten it, but it has never been real loose. Especially after around 1996, Cummins put some kind o sealer on the bolts and they are less likely to fall out. The looseness comes from the mounting gasket taking a set, mostly. I do remove, clean the bolts and holes, blow dry, and loctite the other 4. The two out in the open are perhaps the worst offenders, and if the flange gets caught between gear teeth, you will lock up the engine, breaking expensive parts.
