I am in the middle of tabbing the KDP on my 98, 73k mi and it was sticking out about an 1/8".

My question is, in the crank seal kit I got from Cummins, there is an extra seal that the instructions don't say anything about and I can't find where it is suppose to go.

It is the small black one on the right.



What is it and do I need it?

 

It is a dust seal used in agriculture and industrial applications you can toss it. Goodluck,,Rick

Thats the dust seal. I goes between the damper and the main seal. The Picture I have from TST shows the larger dia (lip) goes towards the main seal. Hope this helps.

Sweet, thanks for the quick answers. Now just got to finish up before it starts raining. LOL

 

I just tabbed my KDP and i got the kit from TST Products. It did not include this dust seal, but from what i have read online it can be used or it can be tossed. The original crank seal that i removed did not have this dust seal either. I would use it if you have it though.

My mew one came with the dust seal. I put it on.

 

I agree, if it came with it, better use it.
