    I've decided it was time to make my own mounting bracket to the 4.0 ohv

    The 1990 van pump came with a serpentine belt pulley that is 5.866" diameter and the pulley bore is 0.752". The factory explorer pulley is 5.25" and the pulley bore is 0.6854" The explorer pump pulley has a smaller diameter shaft hole than the saginaw van pulley so they can not be swapped. I made my bracket to accommodate the larger pulley and still use a stock 4.0 ohv non ac belt

    Hopefully I don't regret not finding the same size pulley as the stock explorer. I am not sure if they make a smaller pulley or if it is needed.

    Decided to make 2 more. One is for the old lady's explorer and the other is for a friend. I am sure he knows who he is.

    Owning a plasma cutter is freaking amazing.

    Well that is just cool. I have a Saginaw pump off some random vehicle somewhere in my parts stash, I may have to experiment with it.

    Could you possibly take the Explorer pulley to a machine shop and have it bored to fit the Saginaw pump? IIRC the smaller pulley would be advantageous in a low speed, low RPM crawling situation.

    Psc has multiple pulley sizes. They don't list the shaft diameter though.
    I don't know if it could be machined or not.
    Maniac used the same pulley as I am planning and he's happy the last he posted about it.

    That pulley is factory to the pump in a heavier van so I don't know why I worry haha

    Just wondering what is the benefit of doing this. :) Thanks

    Saginaw pumps are highly regarded for their durability. They are used on low speed crawling rigs often because they seem to have better flow volume and pressure than the Ford pumps... and they're not made of plastic.

    The Saginaw pumps are easy to modify for increased volume and pressure.
    I'm using that same pulley on my swap and love it. I upped the volume and pressure and it keeps up shenanigans sliding corners and such on the snow.
    I need to draw up one of these in CAD so I can cut them out on my cnc plasma table. I would want to keep the AC compressor though. I like your design, good work!
