PREVENTIVE MAINTENANCE
GENERAL
The key to ensuring the expected return on
investment is to protect against premature failure
with a well-planned and follow-up program of
preventive maintenance.
Preventive maintenance programs examine what
may fail and then formulate action plans which will
prevent failure or downtime. This kind of
maintenance includes lubrication and replacement
or repair of parts before failure but after expected life
has been attained.
Preventive maintenance will save expensive
downtime and wasted energy. It will increase the life
of components. Along with preventive maintenance
should be a record-keeping system. You must know
what problems you have had in the past and when
different components were serviced.
A visual and audible inspection should be taken
every day. Visually you can see if a chain is loose,
oil leaking, sprocket worn; or you can hear a faulty
bearing, noisy chain or any other noise that might
indicate a problem. When something major goes
wrong with some component, a note should be
made to see if a pattern to the problem occurs.
All personnel working in close proximity to the
conveyor should inform maintenance or their
supervisor of any unusual noise.
MOTOR AND GEARCASE
The drive unit should be checked monthly. Check
the motor gearcase for leaking seals. If reducer is
other than Reliance Relialube, check the gearcase
for proper oil level and add the approved oil for your
particular unit. Check for overheating, vibrations
and dirt buildup.
With Reliance Relialube reducers, change oil only
when performing maintenance that requires gearbox
disassembly using Mobil SHC-634. When replacing
the motor, relubricate using Fel-Pro C5A Anti-Seize
or Mobiltemp 78 grease in the reducer bore and on
the motor shaft.
CHAINS AND SPROCKETS
Chains and sprockets should be checked monthly.
Look for correct alignment. In time, set screws may
loosen and allow the sprockets to become
misaligned. Use a straight edge held parallel to both
sprockets to check alignment. Shift one of the
sprockets if the straight edge shows it is necessary.
Keep the chain clean and lubricated. Chains may
be cleaned by wiping with a rag soaked in
nonflammable cleaning solvent.
Lubrication of roller chains is essential to effectively
minimize metal-to-metal bearing contact of pin-
bushing joints of the chain. Oil should be applied to
outside plate and inside plate edges, since access to
pin-bushing area is possible only through clearances
between the outside plates and the inside plates.
Oil applied on the center line of the rollers cannot
reach pin-bushing joints.
A good grade of non-detergent petroleum base oil is
recommended. Heavy oils and greases are
generally too stiff to enter and fill the chain joints.
The Lubrication Guide on page 43 indicates the
proper lubricant viscosity for various surrounding
temperatures.
WARNING
Do not perform maintenance on the conveyor
until the startup controls are locked out and
cannot be turned on by any person other than
the one performing the maintenance. If more
than one member of a crew is working on the
conveyor, EACH CREW MEMBER MUST
HAVE A LOCK ON THE POWER LOCK OUT.
The air pressure must be turned off to the work
area. All pneumatic devices must be de-
energized to prevent accidental cycling of the
device.
Make sure personnel are clear of all conveyor
equipment before restarting the system.
WARNING
REPLACE ANY CHAIN GUARD REMOVED in
order to adjust, check or lubricate chain and
sprockets. Guards are furnished and installed
to prevent personal injury during operation;
maintain them on the unit
WARNING
Do not use gasoline or kerosene for cleaning.
Use nonflammable solvent only.
