Newell Gurus

Bendix part #275707N appears to be the original d-2 governor on the DD series 60 engine.  It has a pressure range of 105 psi to 125 psi.

There are many other ones manufactured by companies other than Bendix.  Such as:

There are many more and any truck repair shop should be able to provide one. 

Here is an article on adjusting the air governor:

There are several YouTube videos on how to change one, including the one Mike Ginn posted:

Tip:  When changing one on a Newell you have to shut off all air compressor(s) and drain all the air from the supply system.  When the "supply" gauge on your dash reads zero you are good to start the replacement.

Hope this helps someone.............................................

can you see any reason to spend 50 bucks on the bendix one vs 20 bucks for all the different aftermarket ones?

I would NOT recommend one with the blue cap, see pictures. It failed after a year, and does not appear to be easily adjusted with a screw driver and wrench.

Thanks Steve for posting this in parts replacement. I will try to remember next time.
