Question

My Mack e7 Keeps blowing unit pump 1 out. I have to keep replacing. It runs fine for a day then back out again. What’s the culprit?

Are they bad or might you be misdiagnosing a bigger issue?

Where are you getting your parts from?

I had 1 jump out of my e7 2 times come to find out the clip that holds the roller on the bottom was bent after 1400.00 to fix the first time I took it apart the 2nd and the roller fell off in my hand bent the sides in just a little no more problem in over a  year..
