Unscrew the BISS all the way out. It'll start to spin in place at the top, all you need to do is get something small and push the BISS the rest of the way out.


new BISSS and Oring from extremepsi. My old one is only 2500 miles old, but better safe than sorry I guess. Make sure it's lubed (I used white lithium grease) before you install.



Time to tap the shaft. Again, I used a #19 drill bit and then a 5mm x .080mm bit with a 10mm long bolt.


A little unorthodox, but using a drill is much easier than hand tapping. I just make sure I put it in reverse every couple of revolutions.



I used new bolts that are flat headed instead of phillips head, I will be using blue loctite this time around.


My dumptube exits right next to the oil return line and I wasn't very comfortable with that. So after some research, I went to autozone and bought 1.5" exhaust flex tubing. This stuff is awesome and only costs 5 bucks!! Don't mind the ghetto "bottom out" shield on my downpipe



As she sits now. Everything is ready to go, I'm just waiting for the shaft seals to complete the entire project




Almost done!

TB shaft seals came in, here's how to put it back together.


I put the seal facing IN and used an 8mm socket to press it into place, no grease was used.



Lube the shaft. I used white lithium grease, anything will really work here.
