I recently bought a rebuilt HE341Ve on ebay. Problem is, the idiot that rebuilt it didn't line up the vane guide and hammered the cartridge into the housing. He also painted both housings with paint so thick that the compressor scrapes.

The paint is easy to remove with a media blaster, the vane guide is toast. I either need to find a replacement housing (the common HE351Ve won't work, I tried) or get the ring fixed. I'm thinking a machine shop can cut off the lip inside the exhaust outlet, cool the ring's retaining collar with dry ice, press it out, flatten the ring and solder the break points.

I don't have an official teardown/rebuild guide so if anyone has a good idea, I'd be thankful to hear it.

Jesus, he smashed it so bad you can see where the vanes were pressed into the unison ring. can you get your money back from this fucktool?

Asfor the fixing, I don't think I would. Just start over

that was seriously FORCED ! Whoever did that is no way an experienced turbo rebuilder

Damn, what do the vanes look like after that?

Wow what a brilliant mechanic. With that amount of force I hope he didn't manage to bend anything in the VGT actuation linkage inside the turbo. Do you know if just the ring from a 351 could work? I know you said the whole housing wont work.

Is there a reason you wanted the 341 instead? I almost wonder if it would be more cost effective to pick up a 351v instead.


Thread highjack.

Here is my current DD. 75 300d. It's too bad it has rust, and the interior is kind of crappy, and it need some new balljoints lol.

The vanes are fine. Some minor filing will clean them up.


No. The 351 turbine is 1mm bigger, just enough to make it incompatible.


The 351 is dirt cheap and common compared to the rare 341 but the 341 is a far better match to my 3.0L diesel. It will bolt to the manifold without an adapter plate and the compressor is 10mm smaller (both inducer and exducer) so it won't surge at lower RPMs but still have enough flow to get my 300hp goal.

I didn't realize there was tha much difference between them. That is good to know. Would you mind posting the measurements of the wheels sometime?


I wonder if you could get someone good enough to straighten and TIG weld the guide without removing it.

Thanks for posting the measurements.

Still need a housing.

I've kept my eye open, no such luck though.

Nearly next year and the damn thing seems to be made of solid unobtainium.

Well the thing was installed and running, but its garbage now. It ebay "rebuilder" left it horribly out of balance. It wouldn't build any boost and its already contacting the compressor housing after just 10 miles.

Damn, that sucks. Are you still unable to find a replacement? What engines do the 341's come on? When I was working at a heavy equipment dealer last year I saw a larger (531ve?) on some new Grove cranes but never saw anything smaller.

It was only used on 06-07 Ford F-650/750 models with the 5.9 Cummins. I know of a used one in "unknown" condition for $450, but McKinney Turbo quoted a rebuild for $400-800 depending on if the compressor, shaft or housings are damaged. I haven't taken it apart yet so I don't know how bad it is. It only contacted 3 times so hopefully its just superficial and they can save it.

Damn. Thats really shitty. Hopefully its salvageable.

Compressor wheel is scrap but the housing looks undamaged.

When my HX40 died from metal contamination thats what the compressor looked like. After tearing it apart part of the center section was damaged pretty badly from the shaft play so a rebuild was going to be difficult. I hope yours turns out better.

Hi I`m new to htis site, you guys rock.Quik question I need to know the difference on the exhaust housings of the he341ve and he351ve,I have a vw gti 1.8t and I was looking the post of the audi tt, and those pics are scary he351ve exhaust housing is too big to fit in transverse vw.

The turbine wheels are only 1mm difference but the 351 housing is much larger and uses a non-standard flange.
