Servicing a multiplier

Does anyone know anyone in the Dublin or Wexford areas who services multipliers (grease the gears,oil bearings) . I have an 6500 sports mag that could do with a cleaning out and although I could take it apart I'm not sure I'd know what to do with it and am certain I couldn' put it back together properly.
thanks
