Default Remove Throttle Shaft from Throttle Body

What's the trick in getting the throttle shaft out of the TB? It doesn't want to slide out easily. Is the shaft pressed in the bearing and/or is the bearing pressed in the TB?

WRX, 03

Right, that small pressed steel thing on the end opposite the TP sensor is just a seal. Behind it is a bearing pressed onto the shaft, and the whole lot pressed into throttle body.

I just pressed the shaft out and the bearing came too. I think some light heat from a carefully controlled blow lamp, or better a heatgun would make things easier.

I used a soft hammer, but press or large vice would be better. Give a tap and see if it moves any.

Thanks Pual, any problems bending the tap for sensor when tabbing it with a soft hammer?

Try using a flat blade screwdriver on the base just back from the tab to avoid that. It shouldn't take enough force to hurt that portion.

Thanks all for the info. Shaft came out fairly easily, just about dropped back in with a little heat and cold. TB looks REAL good, chucked it up in the lathe, did some tapering, and then finished it up with some 600 wet sanding. Milled down the throttle shaft to the depth of the original screws. Installed some button head screws. Owner was happy
