Throttle body rebuild

[cmequestionu]

Has anyone tried this? Is it possible? I haven't found a kit. The reason I ask is because after performing a smoke test there is a leak in the pivot on the opposite side of the sensor, where the spring is.

I would say the throttle body is worn out. I've never seen a kit to do a worn out throttle shaft.

I would be looking at the junk yard for a replacement.

Ok, so I took the plunge and started disassembling my throttle body. I used a mini hack saw frame to cut off the pinched screw threads.

I unscrewed the two screws holding on the butterfly plate. It only slides out one way. One bolt holds the shaft assembly in place. Once I pulled the shaft out I noticed two o-rings.

One on each end. Seems to me these are my problem. I took some measurements and found that I need a metric o-ring M7x1.5. I am going to check my local getting spot to see if I can find a couple.

On a side note, I saw a post on an Explorer forum that someone cut off the half of the shaft that the screws pass through to allow more air to pass by. Seems nominal but is there any reason NOT to do it?

No real reason not to do it besides being a useless waste of time that will potentially destroy the throttle body...

Yeah, but besides that.
