David!

How about some clarification on the seal... Did you have to replace yours?

this will make it to the sticky section huh

That seal has a black ring inside of it that's like cardboard, I don't know what it's really made of. If you just push that seal on the crank it pushes out towards the outside and doesn't seal right. It has to stay facing toward the rear of the motor. I've made this mistake a few times and never could figure out why it always started leaking so quick after I changed it.

This time the kid helped me with it and showed me what I was doin wrong. We put a few bolts in the cover to hold it in place and i held the cover away from the motor so the RTV didn't get jacked up while he used a pick from under the truck to work the seal on the crank so it faced the right direction when we were done. Once you get it worked on the crank all the way around you can push it on and it will stay right but gettin it started is the trick.

If upon disassembly, I find the seal to not be leaking, with removal of the damper, I wipe the crankshaft's snout clean and take things apart.

With the completion of my work, I wipe dry both the crankshaft's snout as well as the shaft surface of the existing seal. Reinserting the installation sleeve (the one I saved from the last new seal's installation) into the crankshaft seal, I reassemble as normal and remove the installation sleeve saving it for the next use.

Make sense? :humm:

If I do find I have to replace the seal, I've found a way to mimic the intent of the Cummins recommended procedure for installing the new seal. It's stupid easy. http://www.dieseltruckresource.com/d....html?t=126282

The Cummins tool that the dealers use have a lip around the outer edge of it that keep this seal pushed in while it seats onto the crank. To get the seal into the cover A press is simple to use and it slides right in.

damn ya'll... :D

Stay tuned for teh Replace your front seal write up! :D

The fly in that ointment (if you will) is that Cummins expects one to have the engine out of the vehicle so as to have full and free access to the front of the engine for the purpose of drifting the seal into place.

Reviewing the thread I posted above presents with Cummins instructing us to press the seal into place with the gear-case cover properly installed on the engine beforehand.

Bobby, you get the drift of my thread there?

Yeah I hear you David... :D

I'll mess with it this week. Thanks for the link!

Here's the tool they use. You just put a bolt through it and into the crank.

Yup. That tool however is not part of the standard replacement seal kit which only includes the installation sleeve as well as the tool used to located the seal in the gear-case cover itself.

That seal installation procedure that Bobby and I refer to allows for mimicking the function of that alignment tool you show. :pca1:
