    I know this will be a slow time of year to get advice-but here goes.

    Last snow of last account the Speedwing developed a major pump leak. It is between the hydraulic pump assembly and the manifold block. I have remove the pump and motor-found 1 mounting bolt gone, and what appears to be a broken weld on the front support strap? I can see between the pump and manifold-the bolt to tighten is behind the s5 solenoid.

    Is this as simple as removing the s5 solenoid and tightening the hex cap screw? Other than this a flush and fill?

    Any advice is greatly appreciated!

    Check for a blown-out o-ring in between the pump and manifold.

    John-thanks. Looks to be 2 o rings. Can anyone tell me if the front bracket on the pump is welded to the frame. I may have a broken weld. All I have right now are the two side bolts holding the pump. I would think there should be more support. Thanks.

    Is this a Power Hitch or Power Hitch 2 plow?

    Here's the manual for the PH plows, it shows three brackets welded to the A-frame to hold the pump/motor; the two sides and one in front. A broken weld wouldn't really surprise me....

    POWER HITCH 1-THANKS FOR THE DIAGRAM-LOOKS AS IF I BETTER GET THE WELDER OUT, THE FRONT BRACKET IS THE WELD THAT HAS BROKEN. Can't complain-5 yrs of use and no other problems. Going to be looking for a 760 for a 1/2 ton before they discontinue(just speculation)
