Waterpump pulley

Hi all, my small block used to be an AirCon car which has long gone. So I'm looking for the correct waterpump pulley for non AC.
What I have works but it's not the best arrangement and I'd like to improve on it.

Cheers Dave

unless i'm wrong (wouldn't be the first time) the ac pulley is smaller to spin the pump a little faster. so unless you have alignment issues i'd just repaint/powdercoat what you have. but that's just me, lol.
neil.

Hi Neil, waterpump is currently driving the power steering atm. Cheers for the input though I never knew that :thumbright:

Without more pictures I could be wrong, but I feel that it is not the Pulley that is wrong, it is the mounting Bracketry / Idler Arm arrangement that is incorrect.

Can you put up a wider picture of the installation, I think the Water Pump should not be on the same belt as the PAS Pump, only with the Crank Pulley and the Alternator. The PAS Belt is a separate (and heavier Belt) arrangement.

Cheers,

Pete

Yes Pete, your correct in your assumption. My car was originally AC and I think it would've been,

Crank, Alternator, AC? & Crank, Pump, PS but I honestly have no idea :dontknow:

This has always been the setup its had from when I got it but, I feel it should be Crank, Alternator, Pump.

Again I don't know :dontknow:

It has however always been reliable and never gets hot.

Cheers for any input.

agreed, all the small blocks i've ever had with power steering had that pump driven direct from the crank'.
neil.
