    Hey everyone I hope someone can help here I have a MM1 system with the under the hood belt driven pump.
    I'm having some problems with the valve body and I want to tear it down and clean it all up.

    Anyone have any info on this, the plow seems to move kind of slow even going down.

    I have a new pump, new belt.
    I'm thinking that the valve body needs ajustment or the valves are upside down.

    Is it a cable valve assembly or is it the electric underhood valve? The cable asembly is really not servicable.

    Let us know what the problems you have are and maybe some more help can be offered.

    This is the cable pull type.
    I did replace the o rings before in one but there are some ajustments on it plus I know the valve can be put in upside down and I just want to check it out.

    Thanks for any info

    Anyone have a older valve body in good shape for sale?
    I checked mine out and it seems worn out.
