Keith Browning Posted April 27, 2007 Share Posted April 27, 2007 I thought I had a stuck turbo on my hands but when I got it open I never expected to see broken vane pinions. There were actually five that had been broken, four of which looked like they had been broken for some time due to the rust and carbon on the broken surfaces. The turbine was beat up pretty badly but this turbocharger still produced some boost. Quote Link to comment Share on other sites More sharing options...
DieselD Posted April 27, 2007 Share Posted April 27, 2007 Wow thats pretty interesting. I tell you these trucks never stop surprising me with some of the failures. I just recently had a turbine come completely apart and just fall out when I pulled the turbo apart. luckily it didn't have time to make its way down the down pipe like others Quote Link to comment Share on other sites More sharing options...
LARRY BRUDZYNSKI Posted April 27, 2007 Share Posted April 27, 2007 It seems to me that the customer would have a serious problem with vibration with the vanes broke off not to metion lack of power. It puzzles me that this turbo was still creating boost. /forums/images/%%GRAEMLIN_URL%%/shrug.gif Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 27, 2007 Author Share Posted April 27, 2007 Larry, I said SOME boost. Just enough where you could drive the truck but it was a total dog - felt like a turbo with the vanes stuck open. Quote Link to comment Share on other sites More sharing options...
Scott B Posted May 6, 2007 Share Posted May 6, 2007 I have seen this in The DT series engines.The Vane design is alot different though.The SRT (There term for the Actuator Motor)Is quite a Bit stronger than The VT'S Oil piston design and seems to be able to break stuff LOL..Lately There are more problems with these DT series SRT motors,The Turbo Vane internals than I have seen with the 365 overall.They are dropping like Flies!!!.And VT work in the last year has diminished to The latest Induction flash.They seem to be staying together quite well without issues even in schoolbuses Quote Link to comment Share on other sites More sharing options...
