    Howdy everyone. I just resently purchased a Komatsu PC-160 LC with a NPK E-210A Hammer. I used the hammer for maybe 12 hrs and noticed that it was leaking hydraulic fluid out of the exhaust hole of the hammer, not extremely bad but enough to make me stop before something bad did happen. It was still operating as it should. I greased the hammer about every hour of operation with the tool in the vertical position. I am not familiar with the internal workings of a hammer, but I hear they can be very dangerous to work on. Anyone have any info would be greatly appreaciated.
    Thanks in advance.

    I haven't worked on an NPK breaker before, but I've never seen an "exhaust hole" on a hydraulic breaker either. Could you post some pics of the suspect area?

    Ok lol. It may be just a vent hole but anyway it has fluid leaking out of it. I'll try to post a pic.

    My guess (I'm not a mechanic & not overly familiar with NPK) that shouldn't be open. It appears to have threads in it? Could be a place to put air for under water operation? A good hammer shouldn't be hard to fix.

    NPK makes a decent hammer, my biggest beef is with their price of parts and repairs.

    That said, if it's still working I would take it in and have it checked over. Meade or Erb look to be the only dealers in KY. I'd call and talk to both to see if they have a hammer specialist that just works on hammers. A surprising number of dealers are clueless on hammers, even ones who sell them.

    I check with my local dealer today and he said that fluid leaking out of that vent hole was a sign that the hammer needs servicing, 700.00 Seal kit. WOW. What can you do but order one and get it fixed. Hope it not out of my capabilties to repair.

    Before you order it I would take it apart. Most of the time you're going to need hard parts also if you want to do a complete job. Before you take it apart, be aware of of the charge on the accumulator may cause things to move when you dissasemble

    I've never rebuilt a hammer, but I know some are easier than others. NPK, from what I'm told, is NOT one of those easier to fix brands.
