Turbo/turbine shaft play for 2006, what is the spec?

[madgreekvw]

I pretty much know the answer to this already, but just for my own sanity I would like some confirmation on this one.



I was changing the oil at 12,500 miles on my 2006 quad cab cummins 6spd manual this weekend and noticed something I didnt like. Since I have to remove the air intake tube to get to the oil filter, I ALWAYS grab the turbine while its off and check it for a bad bearing. Well, to my surprise I can now wobble the turbine a noticable amount, which I believe should NOT be the case. I cant give a measurement since i didnt pull out the dial indicator, but i would think its safe to say you should not be able to rock the turbine up and down enough to notice the slack. I would guess and say its about 10 thousandths, but I know for sure when its pushed to one side, it reduces the clearance from the turbine blade to the housing by at least half.

My 1994 Cummins Dodge had 190k on it and the turbine was perfect last time I checked.



All that being said, i took it to the dealer and the mechanic and service writer are trying to tell me that this is all perfectly normal. I disagreed and then they said they will call cummins to get a spec, but it sound more like they dont have clue what they are talking about. Even then, they only said that after I informed them I was a mechanic for 10 years and am now a mechanical engineer and I strongly disagreed with them. I also told them if the turbine touches the housing, they are putting a new motor in.



One other question along with this, does anyone know of a dodge dealership in the Langhorne PA, or Burlington NJ area that specialized in CTD repairs. (Philly area) I heard rumors that a Cummins dealer can do repairs on CTD dodges, is there any truth to that? There is a heavy duty truck shop nearby that I would MUCH prefer work on the truck for engine related issues.



After the issue i had when i first got the truck and now this BS, I almost cant wait till the warranty is up so i can just fix the truck myself.

Welcome to the forum.

I suggest you call a real Cummins repair facility (like Cummins NW) and ask them for a spec. Your a lot more likely to find a knowledgeable person who is willing to talk to you.

Up and Down movement of the shaft is normal, as the shaft floats in oil while spinning, (as long as its not hitting the compressor housing).



What you do not want is ANY movement front to back. The shaft cannot move in this direction or you do have problems.



It sounds like you may be OK, I know I was concerned the first time I witnessed that much vertical play in my stock turbo also.

jjpage is correct , up and down is ok , front to back is not good , i have a 04. 5 and i noticed the same thing you did , your ok ? Oo.

COOL I just thought the 45psi on my stocker cuased mine to have play ... ..... now about that funny whine it has... ...

About . 020" side to side play is within spec. No In/out (axial) play is spec.

Thanks, now I feel a little better. My 94 has zero up and down play, and my 06 didn't last time I checked it, so this really made me nervous. I will take a measurement and check it again next oil change. I will still press them and make sure its documented that i complained about it though, if the rotor touches the housing 10,000 miles from now and they tell me the engine is fine and they wont replace it I'm going to go postal.



Does anyone know a GOOD dealer in the area north of Philly who actually works on diesels? This dealer does seem to be one of those who would rather look good for the factory rather than help the customer. My father is a 40 Master Tech for GM, and he cant believe how my Dodge dealer refuses to do some of the work they should have done for me. He looked at the turbo and said he has replaced some on Duramax's for less play.



Thanks again for the advice,
