[VAL] Re: VAL Digest V1 #185 - Hinge sag

[waymark1@xxxxxxxx]

The zamak (zinc-aluminum-magnesium) hinge, being of softer metal than the
steel pin, will wear faster especially if it is dry of lubricant or
contaminated with dirt. It is not practical to remove the hinge pin
periodically for cleaning and relubricating, as it will excessively wear
the hinge. Just keeping the hinge and pin oiled to keep dirt out and
prevent corrosion is about all that is practical.
I had vertical sag in my door hinges and fixed it with nylon washers from
Lowe's. I was able to get the hinge pin out of the upper hinge far enough
to slip two washers into the hinge spaces after lifting the door up as
far as it would go. Then I pushed the pin back down and lightly rapped it
in place. The door is now properly aligned.
All noticeable wear is on the thrust faces (axial). There is no
noticeable wear in the bores of the hinge halves or on the pins (radial).
