PREVENTIVE MAINTENANCE
Solving problems before they appear. Some
"route persons" and a few "service persons"
are convinced that preventive maintenance
is just extra work. Someone mentioned
screws that are tight one day then loose the
next. Discover the science of Lock-Tite, there
are two different kinds of locking com-
pounds in various strengths.
LOCK-TITE
The first type we'll discuss is called aerobotic
type locking compound, it is usually red in
color. (aerobotic means it requires air to set).
The red compound is applied to the nut/bolt
when tight. If this compound is used as a
thread locker you had better hire Hercules to
do your maintenance, because this stuff is a
bitch to loosen when improperly used.
BLUE GOO
The other type of compound is usually blue,
it is also available in different strengths. It is
called a anaerobotic compound -this
means that it sets with a lack of air. When
properly used as a thread locker (applied to
threads before tightening), it will secure your
hardware against any reasonable vibration.
SCHEDULED PM
If your route-person will take ten minuets
and apply Lock-Tite to the nuts and bolts
before they get loose, this will solve your
tight today- loose tomorrow headache.
RESULTS
It took a long time, a lot of heartache and
some downright threats, to initiate an effec-
tive PM program in our organization. While
we still have our problems after two years,
we finally are seeing results. So that old
saying "If it ain't broke, don't fix it" goes hand
in hand with "Ignorance is bliss". Fix it
before it breaks and when it does break, fix
it right! That's what will keep the games oir'
the floor and out of the shop.

The 1988 Motorola semiconductors cross
reference program is up and running on the
STAR*TECH Journal electronic Bulletin
Board System (BBS).
This IBM program gives you data on the
following devices: Diodes/Rectifiers, Optoe-
lectronic Devices, Power Modules, RF De-
vices, Sensors, Small Signal Devices, Thy-
ristors, Zeners and Transient Suppressors.
Gives the hard to fmd data on most of you~
IN and 2N devices. This program is very
handy for fmding substitutes that you can
readily buy locally. For more information
