That's part of the seal, that ring is why u have to seal drive it, an can't install the seal in the cover then install the cover. that ring will come right off, I use a 2ft. screwdriver with slight pressure applying in several locations. then toss it in the trash.
On the front of the engine take a screw driver an ever so gently work the ring off, applying slight pressure every inch or two, patience, then take of the oil pump gear, then you can use a 2 jaw puller to pull the oil pump driver gear an the tone gear they come off in one piece they are bolted together again patience it will come off pretty easy with the help of the 2 jaw puller.
Thanks for the information!:hug: I will try the screw driver method in the next couple of day. Now I get to clean up all the silicone on the timing cover, flywheel cover, and the oil pan.
