Just happened along here, but I can't help on that one.
Holset says no. I can't even get the cartridge.
Yeah, it has .020" play and an oil leak on the turbine side. Shaft seems straight and I could only see a little wear on the shaft, turbine side. Probably from coked oil.
ebay, for around $100.
ironically, you are talking to one! How does your thrust bearing look-does the thrust collar fit pretty loosely into the bearing? These things have a tendency to overspeed like crazy and beat the daylights out of the thrust parts AND bend the shaft in some cases.
Where are you guys getting these 431ve turbos, anyway? That's like a $2500 turbo, remanufactured!
^:bs: ^ Only spoken by someone new to the diesel sport!!! :shake:
I bought a HE431VGT with a leaking turbine seal, it's been on a truck for over 4 years and has seen 70lbs of boost and is still running fine! :lolly:
Running these turbos on a 8.9L engine is far from practical!
'06 Kenworth tandem dump truck with an ISM, ate one 2 weeks ago. The thing surged, barked, then broke the shaft. It at least made it to 160,000mi Which I feel is premature, but your saying I got basically double the life of average. Got a new one at Peterbilt it was $3400, returned it, and got a reman from elsewhere. My driver is claiming it's doing it again, but I can't replicate. Would driving around with the exhaust brake on, letting out of the throttle to far between shifts, cause it to be confused and the vgt will not respond quick enough?
under acceleration
Just put a S400sx3 or sx4 on that M11...if you want it to come alive :evil:
