Default GEVO Recall?

I heard/read somewhere something about a "recall" on GEVOs. Is that correct and does that effect all or just some of the GEVOs?

The full report....
CP has bad ordered all its 8800 GEVO, BNSF has not taken all out of service, but some of the SD75M's that were stored are being reactivated as some GEVO's go for repairs. CSX is probably going to wait for each one to explode, then fix it afterwards.

July 11, 2009 GE Evolution Series Turbochargers SB-2009-03G

On another Class 1 railroad there have been two recent turbocharger failures on
General Electric Evolution Series locomotives which resulted in portions of the
turbine rotating assembly penetrating the turbocharger case and exiting the
locomotive carbody. The root cause analysis into the failures is still in process
but preliminary investigation has revealed that the failures that have occurred
are due to catastrophic failure of turbocharger shafts which were produced by
one of two of GE’s suppliers for that part.

The suspect turbocharger shafts affect new Evolution Series locomotives
produced from January 2007 to March 2009 as well as any Evolution locomotive
which has had a turbocharger replaced due to failure or engine change during
the same time period.

Over the next several days the specific locomotives containing suspect parts
will be identified and those locomotives will be removed from service pending
turbocharger replacement. Until such time ALL EMPLOYEES SHOULD NOT
ACCESS EXTERNAL WALKWAYS OR BE IN THE PROXIMITY TO THE LONG
HOOD AREA OF ANY GE EVOLUTION SERIES LOCOMOTIVE (BNSF 5718-7799)
WHICH IS OPERATING OR BEING LOAD TESTED UNDER POWER IN NOTCH 4
OR ABOVE.

Avoid these areas

REMEMBER -- All BNSF employees are empowered to work safely. If
you think a condition is unsafe, protect it, report it, assist in correcting
it, or use your expertise to provide a better and safer way.

Only 44 of CP's evolution series GE's have been sidelined for that problem, I don't know how many on CN but they aren't pleased with their performance and placed another order for 40 more SD70M-2's from EMDI.

GEVO's have turbo problems, and they also have had wrist pin problems you may or may not have heard about. While I was working at NRE in Capreol Ontario, we changed every wrist pin on about 12 CN GEVO's. What happend was that GE switched to a different company to manufacture their wrist pins, and they apparently screwed up the process and wrist pins were snapping in half under load. GE was able to trace all of the locomotives that had the bad pins, and it was well over 200. One problem with the turbo's is that they dont have a water drain like EMD turbo's, and if water collects while the unit is not running, it softens and removes the carbon build up on the blades, apparently causing a huge imbalance which could potentially cause it to blow. While the GEVO locomotive as a whole is very good, the new engine is in my opinion the worst that GE has build yet. I also changed a couple of engines, that were blown up (spun main & rod bearing both on cyl.# L4) due to an "mysterious" oil lubrication problem. I'm pretty sure the GE guys knew alot more about it, but they didn't want to tell me anything about it!

It's not GE alone that has problems without sorest parts, John Deere had their share out of speck parts too. Right now CAT skid loaders are blowing head gaskets. EMD has had its own bad parts in the past like pinion gears on GP50.

The thing is, if GE doesn't fix this issue fast, they will fall back to their Universal series blunder list!

Yea KCS released a circular sayin that were not allowed to be outside on the walkway or go out the back door when the engine is under a load! They are sayin this goes for all our engines with the #'s 4400-4700
