Default Cummins Front Oil Seal: 2 Options?

Hey all...need some help here

I'm replacing the front oil seal. Over the phone, I was asked which one I needed, which confused the heck out of me.

1) Standard oil seal and driver for installation. $48.00

2) Standard oil seal with speedy sleeve $110.00

HUH? $50.00 for a speedy sleeve? So, am I supposed to put the speedy sleeve on the crank end?

I also recall a few people mentioning an upgraded oil seal. Can anyone clarify what I'm supposed to be buying here? And also, does the timing cover need to be pulled off to do this seal?

You should be able to get the seal kit from Dodge for about $35 US or from Cummins for about half that. The Cummins part number I have for the kit is CM 3804899. That may be an old number but it will put you on the right track. You should not need a speedy sleeve. Just make sure that when you install the kit that it is not on any groove in the crank nose. There is some lee way in the depth to install it. You do not have to remove the gear case cover to install the seal, but you do need to loosen it to allow the seal to center itself properly. Make sure the crank nose is clean and DRY before installation of the seal. Use a little blue loctite on the outer edge of the seal so it will not leak between it and the gear case. I've installed several of them. No leakers yet.

VT the speedy sleeve kit is for cranks that have a groove worn in them from the seal.The seal is bigger in the speedy sleeve to accomadate the extra thickness of the sleeve on the crank.I have an extra seal in the garage if you get stuck, i think i kept the install tool you get with the kit as well, call me if need be.

If you're gonna fix the kdp issue, would that be a particularly good time to replace the front seal?

If you order the kdp kit from tst they give you the seal kit with it. Iwould highly recommend doing the seal at the same time as any grunge on the crank will probably ruin the seal when you remove the timing cover since it is a dry teflon type.
