Lexmark T Series -- Broken Left Side Cover Hinge Pin

Pictured below is the site of a broken-off hinge pin on a T640 left side cover. I've 'punched' the centre of it with an awl in preparation for repairing it.


This is pretty easy to repair. Proceed as follows.

1) Drill 7/64" at the centre of the break.

2) Tap the hole 6-32.

3) Cut 1/2" off the end of a long 6-32 screw to make a 'setscrew'. File the cut end smooth and square. With a mini-hacksaw, cut a slot in the cut end to accept a jeweller's screwdriver.

4) Run the setscrew into the tapped hole. Leave 3/16" of the screw protruding.

5) Apply CA adhesive to the upper part of the screw and leave it awhile to set.

Here's how it looks when it's done.
