Mopar Orders Stop to Installation of Ebrakes Until Further Notice?

[Diesel Nut]

The gasket is just a paper one from what I am told, and not too durable. With the V-band clamp style mounting that the brake body and turbo use, its not real easy to get a real good solid seal. Add to this heat, and different matierals expanding at different amounts (cast steel for turbo/brake body, sainless for V-band clamp, paper gasket) and maybe even a little bit of bumps makin the exaust do the whatsusy. All I know is every time I blow it out I have just finnishe pulling a hill with a trailer, so she's HOT, like 1250-1350 hot, and I push over the hill, let her coast a bit, and engage the brake before hitting 65 mph (to keep here under 70, chp preferrs that with a trailer ) and it engages for a short time and just gets progressivly louder. It's a nasty whisle when it goes at 2800 rpms with a load!

For Everyone's Information:



Mopar part number 82208277 is the Jacobs Ebrake for the 2003 & 2004 Cummins.



Mopar part number 82208835 is the Jacobs Ebrake for the 2004. 5 Cummins.



So, the stop sale applies to "all 3rd Gen Cummins Jacobs Ebrakes" not just those for trucks manufactured after 1/5/04 as a previous post had suggested.

Just spoke with Tom Welz at Lou Fusz Dodge in Kirkwood, MO. He confirmed the correspondence from Dodge, was not aware of it until my call to them. He is looking into it and says will get back to me to let me know exactly why they put the stop order out. I'll give him some time to see if he comes through.

My EB started making a whistling when I was towing my 5er in the AZ mountains over the July 4th weekend. It was a different sound that what it made when I first installed it, but I didn't pay much attention to it as many members report this type of sound with the Jacobs EB. I suspect that I may have blown the gasget also. I guess I'll have to take it apart and look at it. Still looking for an answer to: is the problem with the EB or the original truck parts?

 

[PPeters]

Tom Welz just called back (check the post times ) and told me he contacted their District Manager, Terry Hunt. He also confirmed the stop order, but also didn't know why



Tom tells me that Terry is going to find out the scoop and he (Tom) will get back to me.



Stay tuned... .

I just installed my Jacobs Ebrake last Saturday. There is only one gasket that comes with the kit and it goes beween the Ebrake and the turbo. The gasket is definitely a metal base material with what appears to be something like a graphite coating on both sides. The metal base material looks the same as any other exhaust gasket I've seen. BTW this gasket costs approximately $22.



If installed properly the V-band clamp should "squeeze" both the Ebrake and turbo together forming a tight seal.



One thing I did notice during my install, it was somewhat difficult to get a nice flat seal on the Ebrake/turbo side and also a good seal on the Ebrake/exhaust pipe side at the same time. It took some adjusting and even then it was very difficult to see if both seals were flush.

My Jacobs Ebrake causes a whistle also but the sound is definitely coming from the end of my exhaust pipe, not from the location of the Ebrake. It just sounds to me that the Ebrake restricts the exhaust flow in such a way as to create the whistle since it is no longer just an open exhaust pipe when the Ebrake is on. I figure the whistle is no big deal.

 

[klenger]

The reason I suspect the gasget as the cause of the whistle is becasue it did not make that sound for the first few months I had the ebrake installed, but started the first time I gave it a good workout. I hesitate to take it apart if I don't have a good gasget to replace it with.

I havent actually taken one apart myself yet, as the truck was under warranty and the dealers got to do it. When I get my new gasket and take out the old one we'll see. You may have gotton an upgraded gasket. I know this leaking problem is nothing new to them. The dealer mine came from said the Jacobs were a pain to keep running. Out of like 5 or 6 he'd installed, changed my gasket twice, another guy's once, a vacuum cylinder, brake body, and my vacuum pump twice. Seems like maybe my trust might have been misplaced going with the OEM parts?



PS, my truck has 42K miles and is 1yr 2months old

I was planning on installing my EGTand Boost Gauge this weekend. I think I better hold off till this Ebarke issue is determined. Dont want to hear the dealer cry about a hole drilled for the EGT in a part that mey need to be replaced under warantee.

Why didn't you tell me about all of these problems BEFORE I bought my Jacobs Ebrake?

 

[Diesel Nut]

didn't really think it that big a deal, and I thought it was fixed the SECOND time it was "fixed!"

Klenger - my brake has always whistled due to my exhaust and the design of the brake. The oriface in the butterfly is pretty small for the air pushed through it (making it work, we hope) and isn't smoothed out or chamfered, so with that sharp edge it will whistle, but problems arise when the whistling is under the hood or right by the glovebox instead of the smokepipe :-laf

Here's the latest, not a complete answer, but ... .



Terry Hunt (Dodge Dist. Mgr) got back to Tom Welz of Fusz Dodge in Kirkwood MO with the following. Engineering is redesigning the clamp for the exhaust side of the brake. SUPPOSEDLY this is a minor problem, and the issue of underhood fire was not the reason. HOWEVER, Tom could not get the reason for the redesign either, only that the problem is minor, and not all customers may even need the redesigned clamp. No ETA available for the redesigned clamp.



I told Tom that seems a little suspect, since they are stopping sale on all brakes for 2003 and 2004 products. If the problem exists to the extent that they stop sale of all parts in dealer inventory, then I would imagine that anyone who has one has the problem.



I guess we'll find out...

Several points I didn't mention above.....



1 - we advise all customers to retighten the connections after 200 miles... or bring it in to us to inspect and tighten...



2 - my 01 and my 04 you can't hear a whistle when it runs... . are you guys sure you don't have leaks... . I use a 4 ft piece of heater hose and listen... . as you approach the leak you can hear a hiss in the hose...



3 - if you think you have a leak tighten the fasteners.....



4 - I have 3rd hand information..... mind you..... 3rd hand... that there have been some problems... . I haven't looked under the hood of my 04 to see where this hot exhaust would go..... but remember it would be at 60 psi... . and if you'd just pulled a hill... the whole exhaust would be close to 1000* This temp is from the hill pull, not the application of the exhaust brake... but an exhaust leak at lets say 800* at 60 psi would set fire to A/C hose..... etc.....



Hope this helps.....



BTW if you ever seen one of these trucks on a dyno with the hood up... . and pulling 240 or so HP you'd see the whole exhast system glow bright red about a ft or 2 down the exhaust stream... ... its will surprise you how much heat is generated...
