Got some teaser photos from the vapour blasting shop.  I'll take more photos when I get the parts back.  Looks good to me!

I picked up the vapour blasted parts this afternoon and took a few more photos.  Very clean; the throttle body was disassembled by me for internal cleaning as well as the installation of new bearings.

Driving the old ones out was easy - remove two circlips on the shaft end, remove the throttle spring holder from the shaft after marking its position, unscrew the 4 staked screws on either side that hold the bearings, tap the shaft out with  brass drift, tap the bearings out with a perfectly sized brass drift (there is the smallest of shoulders available to do that).

After its cleaned up I will reassemble it with the new bearings that you see in one of the photos.  The old ones were shot, damaged by road salt I presume.

Throttle body is reassembled.  The screws were staked at the factory because the distance between the two plates determines the clearance between the throttle body and the throttle plate.  The large round inserts assure the air seal.  I didn't stake the screws but I did put blue Loctite on them.  The plates are snug to the throttle body but the screws are not "tight" but just touching the chamfered recesses in the two plates.  Now that it is all together, the throttle action is magnificently smooth!

I also took the wrong fuel filter for blasting so the vapour blaster guy will do the "correct" one for free on Wednesday!  The inside of the filter bowl that he blasted has severe rust pitting and the "correct" one does not.
