as far as we know through the factory, the 1st catastrophic rod failed DD15 is right here in calgary Alberta. in a 200 hour 2008 Western Star. this was already 3 months ago, but heres the pics I got.


sorry camera phone is the best i could do

 

EDIT I bet that was loud

 

That's sure not a very good advertisement for that engine. Company I used to work for had a series 60 blow the crank out the bottom so bad you could look across at the steer tire on the other side.

 

WOW!!! That is the worst thing ive seen so far for the new dd15. Most catastrophic thing ive seen down here was the Fuel filter housing cracked due to it freezing solid.

 

Our shop has repaired so far on the dd15, 3 air compressors, 2 high pressure fuel pumps, 1 water pump, 1 wrist pin failure. Give it time, will show its ugly head like the MBE engines.

 

everything has a failure rate, its what keeps me working. I don't mind the 4000 and 900 MBEs pretty easy to work on, depending on what chassis its in though. Ive done a lot of MBE 4000 turbo failures. and at $3900 bucks a pop no labor they're not cheap.


heres one mbe 4000 compressor wheel explosion.


series 60 pre-EPA'04 - pulled the turbine wheel out of the bottom of the stack . and to be perfectly honest. the compressor side spun free no axial or radial play. didn't touch the housing. to look at it you'd never know there was carnage on the other side.




complaint was exhaust leak............

 

HAHA that first turbo pic looked like my stocker did when it went to the rest home.... At least it sounded pretty cool when it let go!!

 

I like the hole in the exhaust!!

 

Ouch. I'd like to know the price of those parts/labor.

 

HLS............man what happened? Other than what the big hole. Not YET seen that down here. Had one come in last week with a bad injector. What a PITA to overnight a new one from DD.........

 

Some of the abuse tests we run at the Tech Center occasionally have some pretty amazing carnage. Of course, nothing I'm allowed to show (or even have pics of), but it's impressive damage.

Sometimes we get overspeed engines that don't make it. It's designed to be a "gee, I wonder if it can survive this" sort of test. Any time your are running an ISX at 150% of rated redline rpm for over 100 hours you can sometimes see big booms.

Yes, 3K + rpm in an ISX. Ouch!

 

Heck, they all break! This one was from neglect! This is just one of many I have seen. I had one that the rod cut the block in two. the head was all that was keeping the block together.

 

was apparently knocking, then kablam. barfed its guts out. DD air freighted a whole engine in. took like 4 days to get it. I'm pretty sure they pulled it right off the assembly line.

 

in addition to the blowout we've done 1 HG, 1 head R&R. and some other minor odds and sods. It pulled heavily on the MBE family in the design features for sure. but I think it'll be a good one in the long run.


han solo what shop do you work at?

 

Jeez, that's something else about the DD15 damage. I work for a Freightliner dealership in Lancaster, PA and two weeks ago I did a PDI inspection on a brand new 2010 Freightliner Cascadia daycab with the DD15. It hasn't been the first time I've seen or worked on a truck with the new engine and I do have to say they are quite as anything. Really something else for a diesel engine, but now a days everything is quite with the DPF exhaust setups and state of the art fuel injection. Now that I've seen one that had this kind of damage I wonder how well they will turn out for use in the heavy trucks. Either way I'm a fan of the older mechanical diesels always, even if we are talking about the big engines!
