I removed the TPS before moving the TB, which is why it isn't in place. The other thing is the IAC.

Be careful when you're prying. The part the spring wraps around is some sort of polymer and I image may be fragile. I didn't test it.

These screws are brass, I believe. Use the properly sized screwdriver so as not to damage them

Remember the bore is 52mm diameter.

When the throttle/butterfly valve plate is closed, it sits at a 16deg (8 on each side of the center line) angle off of perpendicular to the axis of the bore. This means that the width is the diameter of the bore (previous photo), but will be wider on the other axis (becomes an oval)

There are bearings in there that the shaft rotates on. If you're doing anything to the housing, make sure you thoroughly clean them out and grease them before reassembly.

The slot is wider on one side than the other (this side is 52 mm while the other side is wider). Forces the plate centered in the bore.

Width of the slot, so when I cut my new butterfly valve plate, it needs to be .060" thick.

This gets mounted in the vise, then a 59.55mm diameter circle is cut, and I end up with a perfectly machined and sized butterfly valve for my 60mm throttle body.

Hard to tell, but the correct bevel is on it.
