About a month ago,I lost my original turbo when my remote oil cooler/filter line blew and I lost oil pressure.No biggie,it had almost 200K hard miles on it and a Banks PP with the big turbine housing and wastegate.25-30PSI

So I hit the local diesel shop and 900 bucks later Im putting a new HX35W onto my turck with the old Banks turbine housing.I tighten everything up,prelube the turbo and idle it for 5 minutes before heading out.I get on the main road and as soon as I start to make boost,POOOOOOF!!!!!
I figured I blew an IC boot or somn'.Itd happend before and it sounded just like that......NOPE.I popped the hood and immediately noticed the compressor housing was falling off the front of the turbo.Chewed the housing and blades up a bit and did who knows what to the balance of the shaft.I have to guess the big EDIT snapring was never seated right from the beginning.
I mean,I know the warning tag said to clock and then tighten the housing bolts once the turbo is installed,that makes sense,you never know what postion youll need depending on the application.But what are the odds they left the big EDIT compressor housing snapring out of its groove for that purpose?I cant get that **** thing to compress for nothing,not that Im planning in still running the turbo,I just hope the shop I got it from will play ball,because I honestly dont think I did anything wrong.Anyone else had this happen with a re-man turbo?

 

I'd say it was a snap ring issue that caused the problem, but my biggest ?? has to be the $900 for stock HX35w???? that seems pretty high to me, could have gotten alot better turbo from HTT or Industrial Injection for that kind of money, might wanna look into a refund for the 35 & then give one of those guys a call they can hook ya up, Dusty

 

If the snap ring wasn't installed into the groove, then the compressor housing would have moved and fallen off the first time you handled the turbo or even went to tighten the V-band clamp for the elbow casting.

 

I'm gonna have to disagree, when I had my comp. housing off to re tap the hole for the boost elbow, when I put it back together it seemed to be seated & tight, but I took a small screwdriver & pecked on the snap ring all the way around the housing & it seated farther under the lip on the housing. theres a chance that it could have been holding pressure enough to keep the housing from moving & seem tight, but 30+ psi. of boost could have been enough to break it loose, just my thoughts, might give HTT or II or City Diesel, a call & see if they've ever seen anything like this, good luck, Dusty

 

Got it all figured out.

The housing was tight when I installed it.It wouldnt rotate at all,but the relationship between the center and the compressor was right on,so there was no reason to turn or adjust it.I checked the snapring and it appeared to be installed correctly so I tightened up the exhaust housing to set everything in place.
When I returned it,the shop was very helpful in getting things right and after about an hour they had a cure and a cause.Apparantly,there are two compressor housing styles for this turbo,those with rubber o-ring seals and those without.Those with the seal must have a skinnier snapring installed because the o-ring's width holds the housing forward a little.My new turbo had the rubber o-ring and the wide snapring.Since the snap ring is beveled in the back,it initially started to drop into the groove,but its maximum width prevented the ring from fully seating down.Thus,once pressure was applied,the snap ring ran back up its beveled ramp and popped out completely.It boiled down to a manufacturing error.

The guys there gave me a slightly larger turbo in its place.The hotside looks the same(which doesnt matter since I have a Banks housing to install on it) but the compressor is quite a bit bigger and doesnt have any kind of silencer ring installed.The inlet is bigger around and he said the compressor wheel was also larger than the stock unit.Score for me....

And yea,the cost might be high,but its a buisness work truck.Its all deductible and the boss is more worried about getting it quick and local.

 

10-4 on the business application, & glad ya got the thing fixed!! Dusty

 

Cool.
Picked up 3-4 more lbs of max boost over the old turbo and its a hair louder without the silencer ring.
Now to punch out my cat so the straightpipe system can breathe.....
