Apple original right hand hinge & clutch for all models of Titanium PowerBook G4. In this case, the B-grading is due to the fact that the fragile cosmetic trim which runs above the clutch axle has snapped off. It is included and so can be bonded in place along with the main hinge. This is the hinge which sits above the F12 key.
Please note: The fitting of these hinges is not a simple task since the lid casing on the PowerBook is glued together. The design of these Apple hinges was flawed, making them prone to snapping and this flaw was not corrected so this replacement hinge has the same inherent weakness and will break if not fitted correctly or if misused. The design relies on the glue holding the hinge in place taking all the strain of use so it is critical that a suitable glue is used. The hinge must be fitted using a 2-part epoxy resin (such as Araldite) and left to cure for 24hrs before use, irrespective of the quoted cure time. The hinge must be set in glue along the full length of the vertical strut and around the corner. The T6 screw should be replaced but in itself will not provide any significant strength to the hinge and if it takes any strain due to inadequate gluing, will cause the hinge to sheer where it passes through it. Hinges which snap due to incorrect fitting or mis-use will not be replaced or refunded. See our resources page for link to a photo guide to this repair.
