    thinking this is not normal?

    took my plow off the truck this morning (1 month old super-v ld). you're supposed to put it in float and push the lifting arm down as part of the dismount process. when i did that, i noticed this fluid seeping out of the top.

    you can see where it's coming from as well as where it's dripped onto the hose below.

    Not normal. Should get replaced under warranty

    yeah i didn't think so. at first i though it was possibly grease on the piston but it's definitely not grease. gonna contact the dealer.

    It's probably the top seal.

    The only way fluid gets out that top seal is if the packing on the ram inside has failed, allowing fluid to bypass the piston. Warranty replacement of the lift ram is suggested.

    thank you. spoke with the dealer, gonna bring it down there in the next few days.

    does anyone think this may have something to do with the stacking stop bolts i removed? in this thread..

    http://www.plowsite.com/showthread.php?t=154116

    is it possible that after removing these bolts the ram over-exteneded itself when raising the plow, causing it to fail?

    In theory. I would put them back in before going to the dealer, and also make him look at the damage to the stops.

    i was thinking the same thing.

    is that possibly the cause though?

    Could be. Overextending the cylinder could tear up the seals.

    interesting. it doesn't seem like it's over-extending. it stops raising when the stops make contact. who knows i guess.. i'll put the bolts back on and bring it down. i'll be sure to mention the damage those bolts are causing too.
