Have Truck Repair Questions? Ask an Expert
What do you mean it works but no power? ? No power in the engine when it works? Or no power to the selinoids?
In that case first you need to readjust the overhead and put the valves and brake back in spec. And if that still does not help suspect the engine break selinoids and not working properly. This is a common issue but most times the adjustment is just out. The engine brake is adjusted to 7mm and requires a special tool. Have a dealer or Cummins perform the troubleshooting and repair if needed
