    If your wiper seal leaks you might as well rebuild the whole pump because if the wiper seal leaks the rest of the o-rings and packings are probably shot.

    Thanks
    So I just basically remove the top bolts and pull the ram out and replace the wiper seal???
    Does anyone make a boot or sock or something that can go over/cover the ram to help keep moisture off it.... like a shock cover ??
    Thought I saw one once but cant find anything like it now??

    Streetscrapin is right, if your wiper seal is leaking you need to replace the o-ring on the top cap too, and probably the ram packing. The wiper is not the seal, it's there to guide water/ice out, not keep oil in. First is packing, next is o-ring, then wiper. I'm about to do all three on mine. Go here:

    Do a word search on that page (ctrl F) for wiper and look at the paragraph. These guys also say you need to o-rings for the cylinder and tank, and washers for top cap nuts, etc, though I've had my pump apart a few times without every replacing anything. This time I did pony up the $30 for basic rebuild kit.

    You can get a complete pump rebuild kit for right around $40

    I just replaced all the o-rings and seal on my pump for the first time. It only takes about a couple of hours (first time) and for $40 dollars for a master seal kit off eBay, you might as well get them all while you have it apart.

    I recently put a piece of tarp over my pump when plowing and now no snow blows up on it and I havent had any freeze ups or problems like I used to. I think I was getting alot of water running down the ram.
