I am replacing the rear main seal with metal sleeve on my 05 Dodge 5.9. The old seal had the rubber type. I have some wear on the crankshaft journal so figured I best use a sleeve. My question is, do I need to use the special install tool to push the seal on or can i use a ball peen hammer to drive the seal by striking it at 12, 3, 6, & 9 with tool? I saw the hammer being used in Alldatadiy.com steps.

In addition, there was no install tool with the seal and sleeve. Is this correct? I am confused by the things I am reading. Hear is the part no. 3926126(Seal and sleeve) One note: I can slide the metal sleeve inside the new seal back and forth. I guess I am asking, where is the install tool with this new seal and sleeve?

Someone who is a diesel tech or has installed a seal with sleeve before, please give me feedback. I don't want to have to re-pull my transmission and go through this again for a long time. Thanks for reading!

Update: I added pictures of the seal I recieved from Cummins. 1st pic is overall pic of seal. 2nd, is a pic of the white lip that I can slide the metal sleeve back and forth on.

UPDATE 2: See my last post on here. I exchanged out the original metal sleeve seal out for the rubber type after talking to Cummins.

Thanks Big, but I am still unsure of why my seal looks so different and different part numbers.

have done several sleeve kits on cranks and transmission shafts.

But he is asking this:
He knows it can be done but is there a special tool to use with his new seal and bearing?

anytime you are installing a large seal and/or a speedy sleeve.
be very very careful to start it straight. speedy sleeve is ultra thin, so not much room for error.

the same for the actual seal... make/find a tool the same diameter as seal. this allows seal to evenly seat without damage. sure you can try tapping seal in different spots, but you risk damaging the seal.

have seen some kits come with driver tool, some without.
you will always receive a plastic sleeve that allows seal to install on bearing surface without damage. but that's really more useful on installing the front crank/timing cover seal.

follow the instructions if seal is to be installed dry ... some seals specify silicon lube. it's always OK to use hylomar or your favorite sealer on outside mating surface of seal to metal.

The seal with the sleeve is to be installed with the tool. You will need to get it from Cummins, or maybe you can borrow one from a shop that has it. The sleeve must be pushed into position @ a specific depth from the end of the crank, & it must be pushed on evenly all the way around. The seal without the sleeve comes with an installation tool in the package because that one isn't critical to get the sleeve in right. That one you drive in with a hammer, or mallet. Also I've found that the Cummins tool needs to be rotated several times in the process of pressing the seal in place, or it will get ****-eyed on the way in. IMHO get the tool, & do it right, or you'll be doing it over.

I appreciate the feedback. Good info to know. I am calling Cummins to see about the installation tool. I surely want to do this repair right the first time. This has been a pain in the a$$ and a lot of downtime especially when you don't do this all the time. Thanks again guys!

From the picture that I posted, do I first remove that metal sleeve from inside the seal and install it first then the orange seal follows?

bigwheels94

NO! The instalation tool presses it in place as an assly.

UPDATE: I went back to cummins. There is a 250.00 dollar install tool with that original seal and sleeve that I will need. So I talked to the service department. They told me if I didn't have any major grooves on the crankshaft to put a regular seal without sleeve back on. I exchanged the original pic out for the rubber type.

Now, I have a question...they told me how to install it, but I forgot one thing. I know I have to press the seal into the housing that the seal sits in being I am replacing the seal housing also. Question is, does the metal install tool that presses the seal on go in with the crown that sticks up first or the other flat side that has the valley in it? This is all then I can go install this and get it over with.

The install tool has a flanged area around the outside on one side. That is the side you press on, & when it's bottomed out all the way around the housing you're done. It can only work one way.
