Regarding the ignition rotor bolt: The Factory Workshop Manual lists this connector as a self-locking bolt with a torque value of 4 Nm or 3 ft/lbs. However, that’s only because there is some micro-encapsulated adhesive applied to the threads during production. Section 15-24 goes on to say that the screw must only be used once, or when re-used, applied with Loctite 221 (which is the low strength, U.S. equivalent of Loctite 222MS). Anything stronger than this will likely result in a stripped bolt head during the next removal attempt.
