Topic Information Provided by: JohnnyWadd Here is a easy way to pull the stock tbi throttle shaft seals. I did this with the throttle body and mixer off the manifiold. With a dremel or 90 degree drill you could use this method on car. The old ones i encountered where crusty and had leaks and would not pull out with a bent pick so here is the trick to help. Drill 1/16 holes like this (dont drill past the seal or youll really have a throttle body boost least) http://i1187.photobucket.com/albums/z388/starionkiller/how%20to%20pull%20the%20throttle%20shaft%20seals/2011-09-08123358.jpg Now use two really small screws and thread them in the holes. Use small enought screws that they dont scuff the throttle shaft. http://i1187.photobucket.com/albums/z388/starionkiller/how%20to%20pull%20the%20throttle%20shaft%20seals/2011-09-08124523.jpg Next turn the screws in on either side and the seal will push out. http://i1187.photobucket.com/albums/z388/starionkiller/how%20to%20pull%20the%20throttle%20shaft%20seals/2011-09-08124529.jpg http://i1187.photobucket.com/albums/z388/starionkiller/how%20to%20pull%20the%20throttle%20shaft%20seals/2011-09-08124337.jpg A deep 9/16 socket makes a perfect seal driver for the new seal. Lube first with automotive grease just a thin film. Sil-Glyde worked great for me. http://i1187.photobucket.com/albums/z388/starionkiller/how%20to%20pull%20the%20throttle%20shaft%20seals/8a05e0de-8599-4c46-b506-a144fef9f1df.jpg If you are afraid to go after it with a tiny drill bit... http://i1187.photobucket.com/albums/z388/starionkiller/how%20to%20pull%20the%20throttle%20shaft%20seals/20150415_195904.jpg At less than a 1/4 inch, a step bit will aid in depth control.
