    Porter Cable BN200A Air Nailer, would not fire - massive internal air leak

    K - September 7, 2018
    👍 1 of 1 people found this instruction helpful
    Tool Type

    Nailer

    Difficulty

    Easy

    Time

    15-30 minutes

    Tools Used

    , Allen wrench

    Removal of the cap (4 internal hex cap screws) revealed a broken O-ring. There was a gasket under the cap. I ordered the most likely parts to wear or leak. No other tools were required to disassemble enough to replace the piston seal, and another O-ring in the cap. I lubricated the O-rings and piston seal with Vaseline. After reassembly, the nailer performed like new.

    Big endorsement for ereplacementparts.com. They had the parts to keep this tool in operation.

    Easy

    Time

    Less than 15 minutes

    Tools Used

    Screwdriver

    The nailer was not shooting the nails, so I removed the 4 screws securing the top cover of the nailer to expose the piston and removed the "O" ring and split ring and replaced both with the new ones ordered from Replacement Parts. Replaced the top cover and hooked up the unit to my compressor and I was in business again. It was an easy repair and replacement of parts, and not necessary to buy a new nailer. If you have the same problem I did just take your time, pay attention to where the rings were situated as you take down the internals, replace them and you will be good to go.
