Pyrometer
This was the part that I was most worried about but it ended up being super easy. The general consensus is that in order to get a "worst case" reading, it is best to install the thermocouple in between cylinders 5 and 6. This is considered to be the hottest location and thus will give you the earliest indicator of an EGT problem.
Drilling the manifold was very straight forward. I was unable to find the required "R" drill bit locally so I ordered the bit and tap from Diesel Manor along with my transmission line. If you decide to install the thermocouple in between 5 and 6 like I did, you will definitely need a right angle drill or a right angle adapter for your drill. I used an 18V Right Angle DeWalt and it worked perfectly. I started with a very small bit and worked my way up slowly to the "R" bit. I used light pressure on the drill and had a shop vac placed over the hole to vacuum up all the shavings. Once I was finished drilling I used a pen magnet to pick up all the shavings that dropped down into the manifold. I was very surprised by how little there actually were.
Tapping the manifold was a different story. In hindsight I should have greased the tap as a lot of shavings made it into the manifold. It took numerous passes to get the magnet coming out clean.
Now it's time to install the probe insert. Apply anti-seize to the threads and screw in the insert.
Install the probe into the insert doing your best to place the tip in the middle of the exhaust stream. Tighten the nut and you're done.
