Well installed a new front oil seal yesterday. (Not too bad of a job if you love working in a cramped area. bruising your knuckles etc.)
Today it leaks again! I'm maaaad!
Good part to it is that I did also tab my KDP- it had already backed out very far. Now having to redo it all (including waiting for the parts)is the bad part.
Anybody got the same problem and a solution? I do not intend to pull my oil seal daily just to have it pee on my leg next day!

Marcus they make a wear sleeve for the crank snout which on a rebuild cummins puts on. Make sure that you don't have the larger seal made for the wear ring application. Also if the crank is grooved too badly, get the wear ring to fix it along with thelarger seal. That seal is a tight sucker going over the plastic installer.

the seal is teflon and sometimes needs to wear in some to seal. Might give it a few days running to see if it seats.

 

I used a drill press to install mine into the gear case cover. Its a tight fit.

When you put the cover back on, get some metric bolts and cut the heads off. These can then be used as guide pins to support the cover while you ease it over the plastic starting tool.

 

Hauling, do you by chance know the pat number of that repair sleeve and oil seal kit? The crank has some grooves, but nothing I wouldn't tolerate with a non-teflon seal. I'll try and run it for some days now and see if it gets less, but actually it seems to get worse at the moment.

Barney- it wasn't hard to install at all- used the topmost bolt for the cable loom as a guide on the top and a good push with both hands got the cover right on. Getting the seal into the gear cover was easy- shop has a nice set of presses and adapters etc.

I don't have the oversized seal number, but would be glad to call Cummins to get it for you if you need. Let me know.

 

its called a redisleeve or sealsaver if u ask for it by name they will know what u want.

 

Glad you have the proper tools and accessories to help complete the job.

I also used a gear case cover gasket from a '98 12-valver. I wasn't too keen on trusting the cover seal to just RTV. Its too easy to get a bit of oil on the sealing surfaces, resulting in a leak.

 

Hauling : Could you call Cummins for a price on the repair sleeve set? They are backoredered over here and they are quite expensive...

Thanks!

Ok Markus,

The service set that includes the wear ring, seal kit, with the installation adaptor, is part number 3802820. It costs US$71.26 and here would be plus tax of probably 6%. It is in stock.

The source here is:

Cummins Mid-South L.L.C.
Birmingham Branch
2200 Pinson Highway 79
Birmingham, Alabama
35217
Phone (205) 841-0421

I spoke to Michael at the parts counter and do quite a bit of business with them. I asked him if it was prepaid, if they ship to a location like yours and he could not answer me, did not know.

Hope all this helps. If I can help somehow let me know.

Also I think I have a standard (no wear ring) here at the house for one of the engines I have here.

well 2 things- on mine (24 valve) the gear cvr would not accept the older 12 valve gskt-yours did??? do you have a 12 valve or 24??
2-make sure you do not oil the seal at all b4 install.
3-the rtv stuff,do not get in a hurry to torq the cover dwn dwn.let it set up a little.(and both sufaces have too be very clean to work.......in other words sometimes its not the seal at all thats leaking

 

My truck did this. Each time the dealer changed the seal it leaked worse than before after about 15 miles of driving. Finally after the 3 rd time dealer put a sleeve on the balancer stem and problem solved, not a drop of oil leaked since. Hope it fixes your problem, right place to start.

 

thumper: Thanks for the hints, I've made shure that there's absolutely no oil or dirt on the oil seal or the cover surface (and the other side too) - It does definitely leak from the oil seal.
Cummins Austria sais that they do pull the oil seal from the front without removing the timing cover and reinstall it using the seal starter and the depth gauge. Anybody got experience with doing it like that on a Dodge?

Markus if you order that part just send it to my address and I can bring it down to you.

 

I spent two years in Bamberg, bet it has changed a lot. I was 82nd Engineering, HQ.
