I put a wear sleeve on my truck last time the crank seal started leaking. Something has gone wrong and its leaking again. I took the cover off and looked at the surface of the wear sleeve. There is a pretty serious groove worn in it where the front sealing surface hits the crank. It hasn't been on there for that many miles. I've done a couple of these seals successfully so I think I'm doing it correctly. I'm concerned that the end of the crank may have excess run out that is wearing this seal. I ordered a Fluidampr to see if that might help. Anyway, what is the best way to remove the wear sleeve without damaging the crank surface in the process. Thanks

 

Personally, I would cut off a hacksaw blade and use it to cut as much as possible in line with the crank, but not making it all the way thru. Then I would carefully try and peel it away with a sharp cold chisel.

If the wear groove is roughly as deep all the way around, the crank doesn't have excess runout.

Is this a factory seal and speedi-sleeve?

 

Yep its the factory kit they sell.

 

I'm surprised it's worn out already. Something is going on. Those sleeves are hardened stainless and polished, should last longer than the original surface. This is something Dodge offers? Maybe look into an aftermarket item.

Chicago Rawhide (CR) makes the Speedi-Sleeve
National also sells a similar unit called the "Redi-Sleeve

You just need to measure the shaft carefully.

 

I don't believe mine was polished when I installed it. It has more of a dark colored finish to it. I got it from the local Cummins parts dealer. What could be causing it to cut such a groove in a short amount of time.

 

That's a good question. Is it real dirty in that location? Maybe a lot of grit on the sealing surface?

 

Get a dial and check the runout. A fluid damper won't help with run out if that is your issue.

 

Thats a good idea. Will I be able to turn the engine over by hand and see if its out of round or do you think to be most accurate the engine needs to be running. The wear sleeve only had the groove over half of the surface. That makes me think its a little wobbly.

 

Run your DI on the the factory side of the crank seal area. Grinding cranks for 30 years, I'll tell you that factory machined surface's are not as true as we would like/think they are.....

 

Don't do it when the engine is running. Way too fast to even read the dial, and the vibrations will make any numbers completely inaccurate.

 

bar the engine over with the tool or use one of the bolts on the pulley to turn it over a couple times with your dial indicator on the crankshaft.
like someone already said, youd think it would show a wear spot, not a uniform groove.
