Thinking about removing my Turbo to have it tested. Where would I take it for testing and is there a way to test without removing it from Manifold?

Thank's, Kerley

What are you trying to test? About the only test I know of with the turbo on the truck is see if you can make the compressor wheel touch the sides. If it does it failed......

What MnTom said, and you would need to remove the turbo from the manifold to completely check it out. To see if the waste gate is frozen, disconnect the line on the compressor housing and blow compressed air in it to see if the actuator moves. Fill out you signature so we know what you're working with, HY35? HX35? 

CT Cummins24V,

I guess I can't figger out how to add the info. you requested, I'm just old and getting senile. I need directions. Thank you for the waste gate testing info.

 

MnTom, I know very little about Turbo's except every one wants to change them for whatever reason. I just want to know that what I have is working well. 5.9 24v 5 speed stick 4x4 

2002k miles. I am the second owner and aquired this truck eleven years ago with 198k. I don't drive it much unless I'm hauling hay or cattle.

 

Thank you, Kerley

The old school methods of shaft play take effect here.  You check for excessive side to side and in and out play.  If it is excessive, they will tear it down and rebuild it.  I would take it to a diesel shop and let them feel the play and see what they think.  Aside from that, there really isn't a way to test them as most shops don't have turbo flow benches. They usually just tear it down, clean it up, put in new journal bushings, balance it, and there you have it.

Kerley what year is your truck? Usually the rule of thumb is that the manual trucks had the HX35 turbo and those turbos are pretty bullet proof

My Dodge Ram 1998.5, 24v 4x4, 5 speed stick.  The problem I believe I may be having is when I am driving and accelerate weather loaded or empty, pulling a trailer or not, I never feel or hear the Turbo kick in, it just does not sing [wistle] so I just assume there is a problem. I installed the  AutoMeter  fp guage  eight years ago and  have 22p at idle, 20p +- while driving and 18+ WOT. I bought new AutoMeter Boost and Pyrometer guages that will be installed this week. I also bought a Boost tester from ebay. [bought my AutoMeter guages from a vendor not ebay]. Also last year I installed a BHAF from Donaldson with a Heat Shield so there is plenty of clean air available for power. Will the Boost guage inform me when the Turbo is working ?  Also I have fuel guage problems which will be solved by a Vulcan Liberty asap.

Get that boost guage installed and see what kind of boost it will build, on a stock truck with a working waste gate you should build about 18-20 psi on a hard WOT pull.
