    I’m looking at breakers(will be used with a cat 259d) and was wondering if anybody here has any info on them that would help me.
    I noticed some breakers use nitrogen? What’s that about?
    Should I be looking for a high flow unit to match my machine or is standard flow ok?
    How about the cheapo breakers on alibaba or eBay?
    How do you store a breaker?... I’ve heard that the seals will blow out if stored on the side?

    I think most run with a N charge. Its normal
    You don't need or want high flow on a breaker. Most hammers in that size require only 15-18 gpm.
    Like most things you get what you pay for.
    Hammers want to be stored up right.

    I like Okada breakers, had several of them and I am sold on them. If you look up on their website, they have recon units that the factory has reconditioned. I have bought new and I bought the recon model and the Recon unit looks and hits like a new hammer at a much better price. On a machine that size the TOP35 would be a good match.

    Look at NPK, it's a lifetime investment.

    The nitrogen is used as a big spring. The nitrogen cylinders used to be mounted externally in the supply line to the breaker but now they are incorporated in the breaker itself. Lots of problems of hammers not hitting hard anymore are attributed to lost nitrogen charge.

    Hanners should be stored, parked and greased with weight on the moil. Laying them down for extended periods causes the nitrogen to leak. Laying them down to grease allows grease to get between the piston and moil then when it's used the grease can squrt past the piston seal and enter the hydraulic system causing pump failure amongst other things.
    Hydraulics don't give hammers the punch, it returns the internals to where the nitrogen can do it's thing. The hydraulic requirements is what the manufacturers say is needed to make it happen.
    Hope this helps.

    Oh, great. So I get to be the grumpy old man.
    Everything posted above is completely correct.
    But I firmly believe that the most complicated attachment that should be put on a skid steer is a four in one bucket.
    I assume that you at least have glass between your eyeballs and the point of flying rocks.
    Even then, the geometry of trying to use a breaker on a skid steer is just wrong. There is almost no way to avoid side loading the impact between piston and tool. Unless you are working in a parking lot.
    I am a fan of NPK's. But have not stumbled across one small enough to run on a skid. I would recommend bobcat (Nee Montebert, nee tramac) best in weight vs power. But still ridiculously hard and expensive to maintain.

    Mobile wrench, you're not the only grumpy oldman here. Ask my grand kids. But here I'm not. With over 50 years of operating machinery I'm more than happy to pass on advice based on my experience and if someone ignores my thoughts on a matter then its there job,machine and coin. The expense ain't mine.:D

    I like the atlas copco. Used one from a rental company for years, it had the bit worn to nothing and still worked great. They had never had it fail which says a lot as every Tom,Dick and Hairy has used and abused it.I finally bought one just to avoid having to go back and forth to the rental yard. United Rental has them to rent or used units for sale and they service them.
