Blocker pins are mounted by a cylindrical shoulder at one end thereof into cylindrical bores formed in the friction ring. The cylindrical shoulder is the same diameter of at least the portion of the blocker pin immediately outwardly of the friction ring. The cylindrical bore in the friction ring and the cylindrical shoulder of the blocker pin received therein have registering grooves formed therein and a locking pin is pressed into the registering grooves to lock the blocker pin to the friction ring.
