    Dunham bush compressor info



    Looking for rotor specs and dimensions for a Dunham Bush LSC 204 and LSC 255 A, B, C and D models. Have a 204 LSC pulled apart and the rotors have tagged the casing.
    Would be nice to have proper assembly instructions if the customer wants it rebuilt.
    This compressor is on a FES package. FES model 255

    Danod,
    Have a manual & sizes of journals/bearings.
    At the end of the day 0.004" to 0.005" rotor journal clearance & discharge end clearance.
    The LSC has a few variants, one being pressed in line bored white metal bearings, the other field replaceable
    white metal bearings which need no machining (which is best).
    Hartford compressors have had a lot of owners in the last 10 years, the latest a Chinese major share holder.
    If you were to buy parts off someone, maybe they can help out a bit as well.
    Got any pictures?
    How old are they?

    sorry for the late reply. we pulled it apart to find the rotor has tagged the casing. enough damage to warrant searching for a replacement or installing a different brand and making piping changes. it is a machine that requires machining of bearings when installed. not sure of the age, we did order and receive parts. it is a FES package. FES model 255 X-6830 (not sure what the x number is)

    Go for a Mycom, measure length of rotor to give same size, also check motor HP.
    It would be a 250 V series compressor.
    Has been done before.
    I also thought you could get a new DB bare shaft machine?
