My dad is looking to sell his m939 dump. What is it worth?

It’s just weird because when I parked her she was fine and I didn’t have any problems. The only thing that changed was the temperature. Then again that doesn’t mean something came loose or broke in the linkage cable like you mentioned.

The idle will creep up a little past 1500 rpms then Go back down to normal idle and repeat the whole process again. If I pop the pedal the RPMS jump but instead of falling back down it just continues to creep up.

Yeah but if that was the case wouldn’t It immediately rev up like that after start up rather than creep up?

Ok finally figured out how to post videos, now you guys can have an idea what’s going on here.

Nope! She would start off idling normal then slowly climb to 1500 Rpms before I shut her down.

I did a cold start on my M923-A1 (15 degrees) and she started up fine but the idle keeps steadily increasing like it’s a runaway. I’ve been told it’s from air getting into the fuel system but I wanted a second opinion.
