HX35 Rebuild

[Marcus2000monster]

Anyone here rebuilt there hx35? I guess I’m going to attempt it myself tomorrow. Any tips or suggestions? Hope I don’t mess anything up. I plan to check for boost leaks before I rebuild it. Anyone have a diy tester they have built? 

[Mopar1973Man]

Yeah... I did my HX35/40 Hybrid.

 

All I can say is have lots of PB Blaster handy. You might want to have the taps for cleaning all the threads up. Take your time and make sure to assemble everything correctly. If you missed anything during assembly and the wheels won't turn with the nut in place double check again. I forgot my thrust washer. After that, the nut tighten up fine and spun true.

I forgot,,, Is my '99 turbo a HX35?

 

Who're  you guys getting your rebuild kit from?

 

I saw that 35/40 rebuild upgrade on someones web site somewhere  last year but I forgot that too

 

I know my turbo probably needs attention/ bearings and seals , new shaft?

Yes, your turbo is an HX35 @GSP7. Genuine Holset kits can be found at DAP for around $60.  Check if you have oil in the intake side. That's a sign you need seals. And any linear movement of the shaft means you need a rebuild. Wheels and shaft should be OK unless something went through the compressor wheel.

Same kit is used on that hybrid as your stock HX35W turbo.

 

DAP

 

When you take yours apart you'll see how easy it would be to make a HX35/40. Basically the turbine from your stock HX35 and exhaust stays. Now swap out the 35 compressor wheel and housing for the 40 compressor and housing. There is a bit of machine work needed to make the 40 wheel fit though. You'll see what I mean once you rebuild your turbo.

Made it home this morning at 4:30am.  Got my kit from DAP on the porch. Any idea how long it’s going to take me? Iv got a lot of stuff to do today and I don’t wanna year into it if I don’t have time.

[Mopar1973Man]

First time I would put aside about 3 to 4 hours.

Longer if its stubborn. Checking for boost leaks is faster to do

That’s first on the list I’m certain it needs new seals though as there is oil inside the housing.

[trreed]

Oil in the compressor housing could be from an oiled air filter.

It had a s&b when I bought it.

 

Checked boost leaks and found one good sized leak. Tightened the clamp and also installed DAP boost elbow. Truck seems much more powerful but that could be due to the elbow. I’m going to hold off on rebuilding the turbo for now. Going to do a apps reset as well.

[Marcus2000monster]

The truck still feels a little sluggish at lower rpms. High rpms and it will scream.

Its going to be a laggy down low. Just the nature of the truck with no tuner on it.You are pretty much stock right now aren't you? Or did you put some bigger injectors in recently?

All stock except 75s

Try rolling into the throttle and dont stab it. Mine likes that better.

Need to get that Qaud on the way. 

[dripley]

That would help even better. My Comps helps but is smokey until the turbo spools. 

[Mopar1973Man]

Funny part for @dripley ... I Remember seeing him join with a Banks tuner. Then as time went I keep trying to convince Dripley to give up the Banks for a Edge Comp. Just as he bails ship from Banks to Edge Comp. I jump ship later from Edge Comp to Quadzilla. Now I'm doing it all over again trying to convince Dripley to drop that smokey Edge Comp for the clean running Quadzilla. 

 

 

I'm sure he would like to just... 

[Marcus2000monster]

I think my power issue is taken care of. Now I have to figure out why it’s idling funny. And then when a little $$$ rolls in I’ll get a Qaud on the way!  Ill keep my turbo rebuild kit around for sometime when I’m bored.

@5Solas meet up with me in Ontario yesterday. Talking a bit of truck in the parking lot. He's a newbie to the diesel family. So after about an hour of talking shop. I asked if he wanted to take a ride in my beast? "Sure", he said. I played it very cool and drove nice and easy from the parking lot over to the on-ramp of the I84 interstate. Then I let it have it. Poor guy was rather shocked to see that stock looking truck hauling as I hit 75 MPH at the end of the on-ramp merging in. 

 

My last little tweak where I'm tunning for summer fuel and my 2 cycle oil now. It got enough power to break tires loose easy now. 

 

@Marcus2000monster you might want to focus that energy on the Quadzilla next...
