So today I decided to replace the Power Steering pump, it's been making some odd noises, possibly worn internal bearing, and I got a good deal on a re-man.
Lost a lot of time 'cause that damn pulley nut was on very tight. No way to get it out, and you can't remove the pump w/o removing the pulley. Finally drilled a hole through the nut, and it finally gave up - but still with a fight.
I cleaned out the reservoir and mounted it on the new pump, then I went to the hardware store to find a replacement nut. I took the original nut with me and found that:
It won't thread into an M12 bolt.
A 7/16 mating bolt is too small.
A 1/2 mating bolt too big.
And it won't go into an M10.
What the heck is the size (and pitch) of the power steering pulley nut?
BTW: The original nut threads fine on the original shaft.
.....are re-maned units using different shafts, w different threads (the key and pulley itself fit fine on it)?
