Are there low pressure TPIS warnings on a 3500?

Question I have is are the replacement/later manufactured actuators the same as the original?
I’d hope not as mine has already been replaced at 36,000 2 months ago
 
You’re beginning to sound like Stuart......are y’all twins? :D
Ron,
Without doing the actual search in Max Care, I'd say yes it is covered...I think Max Care covers everything except consumables. Not as clear on the 5yr/100K Mile Powertrain warranty.

Cheers, Ron
 
You guys do realize the part Geno's is selling is JUST the shell. While this is the part that commonly fails there are also moving parts in the rest of the housing. Moving parts wear plain and simple.

So there are now apparently two choices.

One, what has been available, the entire actuator assembly from Cummins for $320

Two, the electronics shell for $900. Literally half a component for 3 times the price.

Why are we still having this conversation again? :D:p

Duh! I finally get it. I don't know, 41 years working for the US govt has taken its toll, and sometimes, the TDR kinda dulls one up.

I yield to the logic of JR.

Ron, I Know you are on the same page as evidenced by your earlier post....no offense to you.

This whole bit about being "stronger" than the OEM Holset unit has me scratching my head. You can literally move your turbo vanes back and forth with one finger when actuator is removed on a functional turbo. Extra horsepower not needed. Me thinks it's either a sales gimmick, or they really did crank up the torque but what are the consequences? Ruining a turbo? I rely on Holset over aftermarket on what is practical....but that's just me.
 
ANDDDddddddd, CUMMINS has come out with ANOTHER updated Actuator.

5601240NX, and they're back up to well over $1K....

Not trying to incite a riot, but you better grab you a 5494878RX if you can.

Cummins Reman part #5494878RX available around $300ish for now (which is what I purchased recently) but if those run out the City Diesel Actuator will look reasonable next to the new Cummins part #

JR, we're good brother and on the same page... I finally got it and am one of those who can make fun of myself and dish out a little too.

I think it's great the market is working to our advantage.

Thanks for the post.

Cheers, Ron

Are you referring to the half shell?

I haven't looked into it any further than the price. Literally half the component for three times the price.

If you replace the entire actuator assembly I'm pretty certain it must be calibrated.

Here we go again. Does it slip on?
 
I refer you to post 13 then 17. Your more concerned with being right than helpful. Same as the rotor post.
As for explanations? Everyone knows how it works.

I will admit, I know very little about this actuator, and the reason I am asking questions. I hope I don't need to know any further, but its looks like its a problem child.

It has had it’s share of problems. That’s why someone has gone to the trouble of developing a purportedly more robust electronics package.
 
I see some of these reman's are plug ,and play, so I am curious does that mean they are calibrated ?? I don't see the plug ,and play mentioned on the one you referenced . The other ones I looked at were not too much more in cost, but they were plug ,and play.

It appears JR is referencing the electronic part, its called an actuator kit, so although I did not see plug ,and play , I would guess it is, and requires no calibration ??? Just trying to understand these turbo, and actuator issues, if a problem happens.


For clarification, I bought the entire assembly. (Link I posted yesterday). When you buy the entire actuator assembly they have to be calibrated. It's as simple as aligning the arm on the turbo with an alignment pin provided with the kit, plugging in the new actuator, and running the calibration sequence. It took less than 30 seconds on the pre assembly Cal and about the same on the post assembly Cal. I took some pictures when I did this job. I can start a new thread and throw them up in the next day or so if there's any interest. It's a very straight forward job.

In my opinion this is the way they should be replaced. If not, why wouldn't Cummins provide just the shell.
There are moving parts within the housing. Not only that but you really should remove the actuator gear housing to ensure the turbo moves freely.

All just opinions of course.

I'm curious which units were you looking at that claim plug and play? Since you stated they aren't much more than what I paid ($300) I am guessing it isn't the shell offered by City Diesel (Geno's).
