    Hello.  Looking for a Bracket to mount a second 22si alternator to my QSC 490.  This is a single engine application.  Does anyone make a off the shelf bracket? Thanks Kane

    Unforchunately, Cummins  never made it easy to install any pto type pulley driven device on your engine,  or any of the mid-range engines. Adding a good 2-groove pulley is prettly easy,  it is the belt driven device (2nd alternator,  hyd ,water  pump, or AC pump) that is tough, at least to do it long term right..  It all comes down to the space you have to work with and your in-house skills and capabilities.  Pics attached of various set-ups to give you some ideas.
