We "tag" zerks with different colored caps to communicate that this zerk
requires
FOOD GRADE GREASE, not machine grease.  
This zerk requires
MACHINE GRADE
GREASE
, not food grade
grease.  We code these
zerks with black caps.
We place desiccant bags
into control boxes to
keep electrical contacts
and components dry.  
DI-ELECTRIC BREAKDOWN TEST

This motor (or the wires between its
This motor (or the wires between its
starter and its power connections)
that when there is 482 V DC applied
to the conductors, the insulation
breaks down and allows current to
pass to ground with just .3 ohms of
resistance.  We need to isolate this
problem before the motor is
damaged.  In most cases, this is
caused by a fork lift driving over a
power cord or a motor with damaged
windings.     
MOTOR BALANCE TEST

One of the tests we
perform on motors is an
ohms test to determine
balance of windings.  

This test was performed
again at the motor
terminals after
dis-connecting the power
cord.
This zerk requires FOOD
GRADE GREASE
, not
machine grade grease.
We code these zerks with
white caps.  
Bad electrical junciton box seal allowed water to electrical connections which caused  
premature failure of this crusher motor.  
  
This machine literally
caught fire because of a
lack of maintenance.
cord seal and strain releif failure causes electrical issues.
Hey... if we put a hanger on the other side of this control, the cord could would be free
to hang straight down.   Hmmmm.
Unfinished work:  This edge is as sharp as a knife!
