problem with my TAG

[RustyJC]

Fellows, I checked my TAG when I changed the oil and filter this morning - everything was fine. However, when I was reinstalling the inlet air boot on the turbo, I ran into a situation that might offer an explanation to the TAG turning sideways.



If the honeycomb section of the TAG isn't perfectly aligned with the air inlet of the turbocharger (it actually slides inside the turbo), it will bind and "kick" one side of the TAG's mounting ring out of the groove in the boot. It happened to me this morning - something didn't feel right, so I pulled the boot back off only to find one side of the TAG out of the groove and cocked.



The only way that I could install the boot and know that the TAG was in place was to remove the BHAF, reach in with my right arm through the air inlet boot to maneuver the TAG with my right hand while guiding the boot onto the turbo with my left hand. If I do this correctly, the honeycomb section of the TAG is engaged into the turbo inlet with the TAG flange almost in contact with the front face of the turbo's compressor housing snout when everything is in the "finish" position. If the honeycomb is engaged in the turbo inlet and the TAG's flange is in the inlet boot groove, there's no way the TAG can cock in the intake boot. It would physically have to change position to do so - it has to disengage the honeycomb from the turbo in order to cock. Could a turbo surge do that? Dunno - that's another matter. My point is, if you don't physically guide the TAG into place as I described above, there's every chance that it was cocked during installation.

When I first installed the TAG I noticed same thing Rusty said and to make sure it was aligned right I also did the same as he described, removing the filter and reaching through the boot. Today I changed oil, etc. and removed the boot and TAG to check it out, everything was correctly in place.



Out of curiousity I turned the TAG at various angles in the Turbo inlet. No matter how I cocked the TAG I could not get any part of to come in contact with nut on the blades. It was close but it wouldn't touch, it stays in and I won't lose any sleep.

Which turbo do you have? After reading your post I went out to my truck & took the boot off the hy35 turbo & stuck the damaged Tag in sideways & it touches the bolt on mine.

I did the same thing here. TAG won't come close to hitting impeller or the bolt. PDR HX40 here.

TAG Clamp

Attached is a photo of where to put a band clamp to secure the TAG in the groove of the intake hose for 94-2002 applications. I have also posted installation instructions near the bottom of this page http://www.dieselpowerproducts.com/tag. I hope this helps explain the best ways to install the TAG.

Thanks Dave

I got the replacment ups today. I will get it put back in with the band you sent later this week. I forgot to ask if you want the damaged one sent back or not.

I measured the distance from the end of the air hose to the ring on the TAG as it sits in the indention inside of the air hose. Then marked the turbo housing with this distance (Sharpie pen several places around the circumference). When I put the air tube on I make sure the TAG is fully seated into the turbo inlet and the TAG lip is sitting on the turbo casting edge.



IF the air hose did NOT easily go to the right length marks then the TAG would NOT be smoothly sitting in the turbo inlet and I would know there is a problem. IF the air hose installs to the sharpie marks then I know the TAG is seated into the turbo housing fully.



The TAG ring sits in an air hose indention and seems to say put well. Here on out I will reasure myself by reaching down the air hose from the filter end to feel it is seated correctly.



Not ever had a problem with mine. I do have a KSB1B that Dave had to cut about 1/4" off the compressor end so the TAG would slide into the ID of the turbo casting, which it just barely does, but a nice tight fit.

I like mine

Not sure which turbo... . it is an 02 HO with stock turbo...

 

[DPelletier]

02 HO = HX35

fit and tight

I checked the TAG fit in my HX-35. It's nowhere close to the impeller shaft or nut. Properly located, it fits snug in the inlet. I got a big enough hose clamp which fastens right on the rim of the TAG in the groove of the hose. With just moderate tightening of the clamp, I was unable to dislodge the TAG with both hands. I'm much more confident about it fitting securely now.

Did your problems with the TAG get sorted out? Was considering this purchase, just doing some research here. How did this all turn out? Thanks

I have not had any more problems with the tag getting sideways since dave sent me a clamp. I got rid of the hy35 & went to a piers hx 35 hybred & the tag has stayed put. Just got back from a 2000 mile trip. My hy 35 is sitting on the bench in my shop & I can take the new tag & insert it sideways into the turbo & it makes contact with the nut that holds the impeller on. Maybe the hx turbos are a little deeper because it dose'nt touch the bolt on my hybred when inserted sideways.

I was a little worried about my TAG when it first went in. I think GFrance just answered it above. It "can't" make contact with the stock turbo.

The problem with the TAG is you can't really tell when it's seated right. It is possible to get the thing installed a little cocked and not realize it. I too thought of a couple ways to fix the TAG to the turbo inlet so it didn't move (screws, etc). If you take your time and double check the installation... it shouldn't be neccessary.

Does the TAG make "any" improvements to performance? Yep! They're not huge but measureable... about a . 5mpg increase while towing. I'm putting on 30k miles a year on the truck... so the TAG has payed for itself and then some.

For you guy's looking for a seat of the pants boost from a TAG... forget it. I can't feel anything different whether it's in there or not.
