How do you tell if you have an old style fixed ring, or new floating style? I am installing new turbo on my truck, engine is an 06 cm870

by removing the air actuator from it and checking the movement of the arm to ensure it is smooth and that there are no spots where it wants to hang up.
I did all this after installing brand new turbo, removed air acuator and moved it by hand , it moved okay back and forth but it did make noise when moving, like some friction. Not sure if thats normal? I tried to adjust the clocking a bit to see if it would make it smoother, but no diffrence , so i put everything back the way it was originally with actuator back in place. Could i cause damage by playing with it like this? The turbo company said i should have never removed actuator at all. Let me know asap thanks

A CM870 turbo is air actuated with a simple air-cylinder. It does not hurt it at all to remove that air cylinder and test the control arm by hand.

Who is "the turbo company" your referring to? if you got that thing from ebay or somewhere other than Cummins, your likely pissin in the wind trying to get it to work correctly.

Send it back to them for as much of a refund as you can get and go buy a real turbo from cummins or YTS down in Georgia. Although I've heard that even he doesn't have the right jig to get an 870 turbo just right. Maybe things have changed with that ?? call him and see. 678-588-6197

if u crank up the truck with the control actuator off of it you should be able to press the control arm down, and it should move back up on its own fairly easily from the exhaust pressure against it at idle. If it hangs up, or especially if it hangs up in the full down position then something is wrong with it.
