Product Description

The PennTex PX-833-12V is the most economical way to replace the oil-cooled Delco 50DN with an air-cooled alternative. The benefits of replacing the 50DN with this PennTex unit:

  • Mounting configuration is identical to the Delco 50DN so this PX-833-12V is a drop-in replacement.
  • Utilizes the same electronics and external Delco regulator part #10503807.
  • The existing pulley on your 50DN will fit on the splined rotor shaft of the Penntex unit.
  • Eliminates the potential for oil-leaks and associated maintenance costs.
  • Environmentally friendly.
  • Includes an oil line cap kit to cap off your existing oil lines that were going to your 50DN.
  • 12volts, 330 amps total output with 230 amps at engine idle.

If you prefer not to invest into a completely brand new alternator such as the PX-833-12V and would prefer to convert your existing alternator into an air-cooled PennTex PX-833-12V you can do so by purchasing the PX-8 BCK conversion kit. In addition to the PX-8 BCK and depending on the condition of your 50DN core you will most likely require a new stator as well – Part #410-7330NF.
