Keith Browning Posted September 16, 2010 Share Posted September 16, 2010 This picture came from some guy on the Diesel Stop trying to figure out what failed here. I politely pointed out that it looks like it was arced to a battery terminal after being laid down/fallen down. Ummm yeah. Quote Link to comment Share on other sites More sharing options...

Aaron Posted September 17, 2010 Share Posted September 17, 2010 Yep. That's why the injector rack comes such in handy! Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted September 18, 2010 Share Posted September 18, 2010 Nope, that's a pattern failure from an internal leakage where the hydraulic pressure leaks and eats away at the side of the injector. I've seen several like that (all makes and models) including 1-2 from PSDs at my local pump shop. I'd think Larry should have seen a few by now with all the years he has in. 1 Quote Link to comment Share on other sites More sharing options...

You are totally serious about this arent you. I'll take your word for it as if anyone would know it would be you. But a pattern failure? I have never heard of or seen this. Really? high pressure fuel will do that? Quote Link to comment Share on other sites More sharing options...

Really? high pressure fuel will do that? Yes, I'm serious and yes, it is a pattern failure seen mostly in pump shops because they see so many components. IIRC, my pump guy said internal leakage but I wouldn't bet a lot of money on it. He had a couple on the shelf for show and tell but they were not PSDs, they were something else with that same hole. I was also freaked out by it when I first saw it 15-20 years ago. Quote Link to comment Share on other sites More sharing options...

Bruce Amacker Posted September 18, 2010 Share Posted September 18, 2010 Now you know how a "Water Jet" cutter works. I e-mailed the first pic to one of my pump guys asking for a better explanation. Quote Link to comment Share on other sites More sharing options...
