I'm putting power steering in my 55 1st serie Chevy Truck and need a Pulley for my rebuild earley Chevy steering Pump. The old Pulley has been on the shaft without a nut an anything else but it broke when I pulled it off.
So I'm here in Germany and I can order a pulley with 625 in. Bore. Does that fit??
My shaft is 19mm but I am not sure what that is in Inch, maybe 482 in. ??? | | | | | Joined: Jul 2004 Posts: 5,708 'Bolter | | 'Bolter Joined: Jul 2004 Posts: 5,708 | Bernd, .3937 X 19mm = .748...almost 3/4".

The later ones had a larger shaft & the pulley was an interferance fit & pulled on by a tapped hole in the shaft with a special tool. I,m not shure of the dementions but I can check when I get to the shop tomorrow.

I could send you a Picure with an e-mail but I have no idea how to post a picture from the pump or Pulley.

The large shaft is 11/16" 0.6875 17.4625mm.
There are so many different offsets & outside dia. we would need to see a photo to match it up.
