Dorothy,
Sharon was right. You will need to replace the HeliCoil in that screw hole.
Melco will send you a HeliCoil kit that will include a special installment
tool that is necessary to replace the little coil. If you continue to try
and screw the screws in and out you will damage the aluminum casing and the
screws as well. Look closely at the threads on the screw(s) that you have
been trying to insert and see it the threads have been compressed. If they
are damaged, they will look as if they have been cross threaded to some
degree and will need to be replaced immediately. Screwing these into the
remaining "good holes will result in more damaged HeliCoils. The difficulty
you are experiencing with the screw tightening and this little HeliCoil,
runs a close analogy to a "Chinese finger trap" , the harder you try to get
your finger out of it the tighter it squeezes.
The HeliCoils are usually damaaged by "over tightening" of the screw and/or
a foreign substance, dirt, lint, , whatever......building up in the threads
and starting a problem. Over tighening a screw in a HeliCoil will result in
trying to make the spring smaller in diameter "so to speak" and causing it
to grip the screw tighter and when the screw is being removed, the spring
will not want to release it's grip and kind of cross-threads itself on it's
own threads......hummmm, hope that makes sense.
A HeliCoil is a steel wire or a very tightly compressed spring that is
"threaded" into special threads made for the shape of the HeliCoil. This is
threaded into soft metals such as the aluminum in the carriage housing to
extend the life of the casing threads. Melco has vastly improved this design
in later production models and now uses a steel insert in place of the
HeliCoil system. Much better.
My advice would be to immediately contact Melco and get the HeliCoil kit .
They are not difficult to install and have instructions with the kit. To
remove the old coil, just take hold of the exposed wire and stretch it
straight up slowly and it will pull out of the hole. Be careful to pull
straight up and not much twisting motion is allowed....... you do not want
to break the spring in half and leave some of it in the hole...it is a
bugger to get it out then.......slowly and carefully is the key.
