Has anyone ever replaced one of these? If so, where did you find one? I can't determine if it is a Cummins part, Freightliner part, or specific to Monaco/HR.


This is what happened to it:

    Looking at the part, you may be able to unscrew the socket head and just use a piece of all-thread to replace it.


    If you look closely at where the shank of the threaded section enters the eye section, you'll see IT'S NOT THREADED. It's either pressed into the eye sections or, it's machined as part of the eye section. I've had things just like that break and, all I did was cut it short of the break and, weld on another section of threads. But, I been doing that kind of stuff for years.

    Obviously, if one doesn't have the tools and equipment and or skills for a fix, it's time for a new part, no biggie.

    OK. It looks a lot like the throttle control I had on my 93 Cummins (which did thread on) and I assumed from there.
    Best of luck to you.

  • Cummins should have that or any large truck dealership, KW, Freightliner, Navistar, etc.
