TSB 18-022-06 & TSB-09-004-06

[mfrost]

Has anyone done the engine system enhancement TSB 18-022-06 for improved engine cooling, oil pressure correction reading, etc. Thinking about getting it done along with the overrunning clutch pulley on the generator. Anyone have any esperience with these TSBs, good or bad. Thanks

What is this "overrunning clutch pulley on the generator" thing you talk about?

Lets the alternator continue to spin when the pulley is stopped by the belt upon engine shut down. Stops the belt chirp.

I had the "overrunning clutch pulley" done a couple of months ago and really like the quite shutdown that I now have 'belt chirp" is totally gone.

Wouldnt the extra engine cooling and oil pressure correction reading just make the ECM send different signals to the gauge since they are nothing but security blankets and not actual readings anyway?

The belt chirp TSB was brought about as a result of some of the early belt shredding issues that some of us 04. 5 and 05 owners had. Reduces stress on the belt at shutdown.

Anyone Have The Tsb Number For The Pulley Fix ?

The engine cooling flash addreses fan stategies.

DC really knows how to fix things. Just put the belt on correctly and the problem is fixed but no they have to go and put a clutch on the alternator (I assume). Can you say more dollars to repair when replacement comes due.
The belt chirp has been an ongoing thing since 1999 models and probably earlier.

On the 2 gen trucks a goodyear gaterback was the fix for the chirp. My 06 don't to it, yet.

No, it's not. Do a search on here and on DTR for "belt shredding" and you will have hours of reading. Belt chirping due to high compression shutdown is normal for all diesels, but, for whatever reason, the 04. 5s and 05s had issues with some of us shredding belts for no good reason. My original one went back in August 2004 with only 5400 miles on the odo. At the time, the TSB didn't exist, and dealer just replaced the belt, which has been fine (Knock wood) since.



These 3rd gens seem to put even MORE stress on the belts at engine shutdown, and this TSB will help to lessen that, which will lessen belt wear and hopefully lessen the chances of premature failure, which more me, necessitated a ride on a flatbed to the dealer.

What makes you think Swexlin is wrong? how many belts has your truck gone through?Was it installed correctly from the factory? I have only replaced 1 belt on 1 3rd gen for a failure,and that 1 truck has had many trouble free miles since on the same belt.

The caravan has the one way clutch on the alternator and has not been too bad.

Bob,
Could you edit your post so I know who your talking about.

Are you saying I'am (pwr2tow) wrong or swexlin

swexlin,
You pretty much confirmed my diagnosis that the tsb had nothing to with belt shredding. Just install it correctly and all is fine.

Believe what you want, but my original was installed correctly. Never in 25 years of driving many different cars and trucks have I ever had a belt fail that early. If it were just me - yes, a fluke. But as I said, do a search, and you will have plenty of reading.

 

[pwr2tow]

swexlin,
How would you know if your belt was installed correctly, It failed in 5,000 miles. You yourself said the tsb didn't exist when you had your belt replaced so your truck does not have the tsb update. Even though Your truck does not have the tsb your trucks belt has not experienced any failures since or the last 2 years.

Just becasue DC came out with a tsb for belt chirp doesn't mean that that is what was causeing belt failures. Belt chirping has been on these engines for along long time without belt failure. The failures didn't come until around mid 2004 and lasted only about six months when dealerships found that some of the belts had been installed incorrectly from the factory.

Have you ever heard how a 2002 and earlier VP44 injection dodge cummins shuts down. Very abruptly and the belt stops with it makeing a chirp. The 2003 and newer CP3 injection system dodge cummins shuts down with kind of a rotation noise and not as abruptly. Not saying the newer trucks don't have a belt chirp just less pronounced to non existent. If any truck were to have belt failure it would be the VP44 engines yet they don't.

Because I look in my engine compartment regularly, and I would have noticed it. I'm through debating the point with you. Too many of us have had this particular failure for them to have ALL to have been installed incorrectly. I KNOW all diesels chirp - my Ford PSD was awful. I just saying that there is something about the stress these newer engines put on the belts. The tech had checked mine, and nothing seemed out of whack (pulley, tensioner, etc). Yes, I have been lucky - the replacement has been fine - so far (knock wood). But I check it at least weekly. Quite simply, I don't trust it.



You're entitled to your opinion, I'm entitled to mine. Unless you have experienced this for yourself, you don't really know.

and lasted only about six months when dealerships found that some of the belts had been installed incorrectly from the factory.

Where did you get this information? Do you work for a dealer? Not trying to be a smartass, I'm geniunely interested.

Doing as you suggested, reading on here and other diesel sites for the last 6+ years, keeping up on whats happening, whats hype, what the cures are. From guys on this and other diesel websites that are mechanics at dealerships and see this stuff. I have a good friend that is a mechanic at a dealership. Listening to who knows and who doesn't. Not taking what everyone says as face value until it's been throughly discussed. Learning from experience from my last three diesels. Drawing on 35 years of mechanical experience.

I'am done discussing this, have a good evening.
