removed my faulty TPS and thought I would find a good deal of oil inside, but there was none.

what I did find was a good deal of play in the throttle shaft? should there be ANY play in the shaft?
I am guessing there should be zero?

my throttle bearings have been leaking air, so I have planned to replace them for that reason. also
hoping that new bearings will remedy this float, but wonder if the throttle shafts can wear?

Speedtoys

There should be no play. Correct.

merchauser

^^^ thanks for that^^^

can't believe how simple it was to remove the bearings using the masonry anchor method that Hilton told me about
(2) 4 x 3/8 bolts. took about 2 minutes per bearing.

should I dress the portion of the throttle shafts that sit in the bearing? there does not appear to be anything of concern,
like scoring, but if look closely the center of this photo, it looks more like staining, for lack of a better word. would emery
or crocus cloth be ok to use?

Speedtoys

Id leave it as is. But may be other answers.

The new bearings are by change rubber sealed? If so, more that I would leave them as they are.

merchauser

^^^^the bearings that roger has are double rubber sealed (originals are single rubber sealed)

Speedtoys

Id just go with that and be done.

Put a thin coat of light grease on the flappy axle. Just enough to prevent dislodging the new bearing O-rings when inserting the axle.

Speedtoys

Dislodge? That would be quite the event...
