Front crank seal kit ??

[bgilbert]

Can someone tell what each one of these 4 items are that are in the front crank seal service kit - 3804899? In particular the black piece. I see three of them in the service manual, the red one is the oil seal, clear plastic pilot tool, (I'm guessing), metal alignment tool, and the black one?? It has a metal ring inside of it, it isn't all rubber. The service manual doesn't say anything about it, or maybe it does, I'm just not reading it correctly. It's not pictured in it though.



Reliablegoods.com calls it a SHD_DUS. I'm guessing it means dust shield? Also if anyone knows what it is, tell me the order in which it goes on the crank, in front of or behind the oil seal. BTW, pictured in the 2nd pic is the old seal. Thanks.

You've got it. Clear plastic alignment tool, crank seal, metal install tool shown as a set with the dust seal leaning agenst it.



The metal install tool will bottom out on the end of the crank at the proper depth if you install the seal with the cover on the engine. I've always had the cover removed so I've never used it.



The dust seal will go on last, on the outside. Honestly I've never used it, I always chuck it in the round file with the clear alignment tool when I'm done.

Thank you very much.

:{ Well I might be out another $40. I drove the seal in deeper on the top than the bottom. I'm sure this will be a problem, reckon? This is what happens when one gets in a hurry... .

I would remove the cover from the engine if its not already removed and try again to get it straight.

Sorry 'bout that. Thus the price of experience and knowledge.

Bill. I used two small pieces of 2x4, the steel depth ring and my drill press. On block of 2x4 under the cover and the other block above. I carefully stacked everything in place and slowly started to give it pressure once it started to go I just watched to make sure it was going in level. The Steel depth stop piece won't let it got too far. Worked great after a couple of hours trying to "tap" it in. Mine was VERY tight fit.



Good luck.

Live and learn. I'm gonna see if Cummins will sell the seal only 3935959 and not the $40 kit. In a hurry at night with minimal lighting... not the best way to do things.

Wow, I was wondering the same thing, I am installing one (I hope) today. My dust shield looks different though.

[MTownsend]

well I installed it, It don't leak yet ( knock on wood)



It sure would have been easyer to do before i put the engine in the truck

 

[HPetrat]

Just a suggestion, but I would recommend holding on to the clear plastic alignment tool.

I have used mine several times when doing KDP's or other "behind the cover" inspections for friends (the kind with problems and never any cash to pay for the right parts :-laf ) and have managed to re-install the cover/seal without leaks.

I keep it in a labelled Ziploc bag hanging on the shop wall by the tool box, not only as a reminder of where it is , but also to remind me of how much of a pain in the exhaust installing one of those seals is .



By the way bgilbert, interesting work bench :-laf ,

LOL, I even use my bed for a workbench sometimes. How's that Jeff Foxworthy thing go, gotta move that transmission to get to the bathroom or :-laf?

 

[DValentine]

I would recommend saving the alignment tool. I have pulled the cover and messed up a newer seal trying to get it over the crank.

I had my cover off, set the seal in place with a piece of 2x4 on top, and with one swift hit drove it in flush with the cover. Then I set the depth driver on used the 2x4 and hammer again. The seal was done in about 3 minutes.

My alignment tool slipped to the slide and munched the outer lip of the seal. Another $40 down the tube. I didn't remember the details of this post when I needed them and intalled the cover first using the alignment tool the way the manual tells me to. I think I will remove the cover today and use the press idea. A piece of 3" exhaust tubing works well as an alignment tool driver. It fits right into the groove in the alignment tool.



Dust shield huh? I was about to install the thing as an oil slinger. :-laf



Well, now I have two. One for each side??? Just kidding.



I see the reason for the dust shield though. I have quite a groove where the outer lip rides from dirt rubbing on the seal. The inner lip has almost no wear. We'll see how well that thing works.



TDR to the rescue again. Thanks for your experiences.

My brother in law did a 500cc Matchless Thumper on the coffee table. (Base housing) Heck it was winter and raining, who can work out in that kind of weather. I have done a few carburetors on the kitchen table. Did all my model work when I was a kid on that table.

Bedroom Rebuild

While a starving college newlywed, I build a 63 Studebaker 289-R1 for my Stude pickup in the second bedroom of a little old 2 BR house in Phoenix. That old house had 1 electrical outlet in each room and not every one worked. Anyway, we built the engine in the BR and had to take the engine outside with a hand truck before I put the heads on so it would fit out the front door. Cardboard on the lawn was the next workbench while I put the heads on and then into the truck it went! I still laugh at what that all must have looked like. :-laf

i sure hope i dont mess up the seal i just bought ..... i might not be able to win another one on ebay for 12 bucks .....



no but in all seriousness does it matter which direction the seal go in ... i mean is there an in and a out side?

 

[dpuckett]

Yes, it does matter. You want the "gulley/trough" to go to the oil side/ inside. In other words, there should be a nice smooth surface exposed to the outside when installed.
