First step is to remove the rad overflow bottle
use a screwdriver to pop the round button
Loose then just slide the bottle up and out
Using the fan wrenches one for the fan pulley
the other for the fan...loosen the 6 pulley bolts
   Now break the fan loose from the pulley hub remember this is a left hand tread to remove
the fan from the hub
Remove the fan belt....nows the time to
inspect the belt and replace if needed then
remove the fan pulley
Remove the alternator and carefully set it on
top of the turbo tube....I also removed the
bracket to access for photo's
Remove the fan hub and bracket
I removed the top rad hose (needed replacement)
and the oil filler then I pulled the fan out thru the
top for better access
The drilling bracket is installed the housing is about 1/2 " thick
I drilled almost thru then used a vacuum to remove the chips
remember to cover the damper pulley with a shop rag
Now its time to use the countersink bit drill until you come to the stop
I removed the jig to show the drill hole and countersink vacuum all
the drilling chips  the next step will be to finish drilling thru the
gear housing remember to pull the drill out and keep vacuuming out
any drilling chips
After drilling thru the housing if you didnt hit the dowel pin
then you can tap the hole using the supplied tap adapter
last step is to install the blocking screw and apply red
loctite to only the head of the screw
If you hit the dowel pin then your options are to pull the front of the gear housing cover off
and put the dowel back into place....sometimes you can work it back into place thru the
hole that was drilled (which I have done) then install the locking screw
I have heard of people drilling a hole in the front cover and tapping the dowel back
into place then filling the hole with JB weld
Note
You will need metric wrenches and a cordless drill
the complete job took 2 1/2 hours to do 2 trucks
Fixing the KDP On Dodge Cummins Motors
Using a vacuum puts very few drilling chips into the motor
which fall harmlessly into the oil pan
