Ingersoll Rand XP375 Shutting off after opening ball valve.
by Armando Miranda
Im working on a Ingersoll Rand XP375 skid mount. The machine has a small in-line 4 Cummins, think its a b39, not so sure.
The problem Is that once the machine is started, warmed up and producing air at the ball valve, I open the ball valve half way and the engine shuts down.
It has been recently PM.
It has a new fuel filter, oil change and compressor end serviced has been done as well.
I thought I would check the turbo boost and manually I can rev the engine to full throttle. The max turbo boost pressure I'm getting is 14-16psi.
I was thinking it could be a compressor end problem, a valve not working right and maybe loading the engine a lot to a point it shuts down.
Or a regulator could be bad.
At start up its at 0psi. once loaded it shoots up to 130psi and I can regulated to 150psi. But once again when the ball valve is opened half way slowly. The machine shuts down.
Any pointers on what could it be?Please feel free to call me at anytime, day or night.713-301-4759 or write me an e-mail at, email@example.com
