  • There's a black seal in the kit (3802820) that I can't figure out. My best guess is it's to go over the wear sleeve. And is the depth guide that comes with the kit supposed to slide right in our does it need to be hammered in? Or do I need a new timing cover?

    The lip seal is the black seal in the kit. Here is the link to the install video:

  • Is the seal larger to accommodate the wear sleeve or is it the same size as OE? If it is larger, what is the part number?

    Dakota Chain | 8/14/2019

    It is larger, the only way it is sold is as the 3802820 full kit.
