Brand New Turbo

[lineman]

Can Some one Tell Me how they prime and pre lube a brand new turbo?

Hmm thats a new one on me? All the oil returns to the pan once the truck is shut down anyway. Not sure,but thats a good question? I don't think its somthing that is critical, but Im known to be wrong

I ask because i got my new turbo in and installed it and took it for a drive and 10 minutes later it blew up. Don't want to say what vendor until i can call them tomorrow and see what they say. Anyways i let oil soak into the turbo overnight upside down, installed it and pulled # 30 fuse and cranked her over for 20 seconds each time for 5 times. waiting between for the starter to cool, replaced fuse, started her up let idle for 5 min @ 1000 rpms. backed out of garage looked for leaks for 10 minutes , took for drive and 2 miles later @ 18 lbs of boost, bang, no more working turbo.

I wonder what the first start up protocol is for all of Fords diesels? I can't imagine it's something overly complicated.

Is there any way to prime oil pressure without cranking the engines? On My 1970 oldsmobile 442 after a rebuild i pull the distributer and spin the oil pump with a drill. Anything that easy for a 7.3?

I was just looking at Garretts GTP38R install instructions and nowhere it mentions pre-oiling or priming the turbo, it's pretty much bolt in and go, so I can't help you with that question.

I Looked in service manuals I have, and it appears the the turbo is fed right off the rear main bearings oil gallery. So if the engine is running there should be plenty of oil being supplied to it. I would think that at idle the engine would supply enough oil to take care of lubrication of the turbo.
