for extracting the bearing, i wanted to have the best grip and torque i can get.
so i slide a 16mm wrench on the nut, and held the center bolt with a 13 mm socket.
holding the ratchet in my left hand and turning the socket clockwise, extracted the bearing with no effort at all. in fact, i was a littel bit sorpraised how easy it came out.
one of my fears, was to find out the IMS is not centered (based on other posts i read). i was happy to see it was perfectly centered, and i do not need to remove the third tensioner (a true PITA to remove).
