MAINTENANCE

• Lubrication

The drive chain is pre-lubricated from the manufacturer by a hot dipping
process that ensures total lubrication of all components. However, continued
proper lubrication will greatly extend the useful life of every drive chain.
Drive Chain lubrication serves several purposes including:
• Protecting against wear of the pin-bushing joint
• Lubricating chain-sprocket contact surfaces
• Preventing rust or corrosion
For normal operating environments, lubricate every 2080 hours of operation
or every 6 months, whichever comes first. Lubricate with a good grade
of petroleum or synthetic oil (i.e., Shell Rotella or Mobil 1). For best
results, always use a brush
to generously lubricate the
chain. The proper viscosity
of lubricant greatly affects its
ability to flow into the internal
areas of the chain. Refer to
the table below for the proper
viscosity of lubricant for your
application.
The drive chain's lubrication requirement is greatly affected by the operating
conditions. For harsh conditions such as damp environments, dusty
environments, excessive speeds, or elevated temperatures, it is best to
lubricate more frequently. It may be best, under these conditions, to develop a
custom lubrication schedule for your specific application. A custom lubrication
schedule may be developed by inspecting the drive chain on regular time
intervals for sufficient lubrication. Once the time interval is determined at
which the chain is not sufficiently lubricated, lubricate it and schedule the
future lubrication intervals accordingly.

• Belt Installation

INSTALLING THE BELT
The conveyor belt has been cut to the proper length and lacing installed at the
factory. To install follow these steps:
1. Thread belt through conveyor as shown in the figure for Center Drive and
End Drive Installation.
2. Pull ends together and insert lacing pin. If belt ends cannot be pulled
together by hand, loosen take-ups (in center drive or at tail pulley) and/or use
a belt puller so lacing pin can be inserted.
3. Adjust belt tension with take-up pulley. Keep pulley square by moving both
take-up bolts an equal amount. Maintain enough tension so drive pulley will
not slip when carrying the rated load.
4. Track belt per instructions on page 7.
CAUTION! Excessive slippage will reduce belt life and damage drive pulley
lagging. Never apply more tension than is needed. Over-tension will cause
extra wear to belt and bearings and will require extra power from drive.

• Belt Tracking

HOW IS THE CONVEYOR BELT TRACKED
The belt is tracking by adjusting: Drive Pulley, Tail Pulley, Return Idlers, and
Snub Idlers. The same tracking principles apply to conveyors supplied with
end drives, center drives, or underside take-ups.
PRE-TRACKING INSPECTION
Before attempting to physically track the belt:
1. Make sure conveyor is level across the width and length of unit. Adjust
supports as necessary.
2. Check to make sure: Drive Pulley, Tail Pulley, Snub Idlers, and all Return
Idlers are square with conveyor bed.
3. Make sure belt has been properly threaded through conveyor.
4. Make sure belt lacing has been installed correctly and is square with the
belt.
5. Check for improper loading. Feed should be in direction of belt travel,
centered on belt.
IMPORTANT: When belt tracking adjustments are made, they should be
minor (1/16 in. at a time on idlers, etc., should be sufficient.).
Give the belt adequate time to react to the adjustments. It may take several
complete revolutions around the conveyor for the belt to begin tracking
properly on long, slow conveyor lines.
A) Stand at tail pulley looking toward drive and note what direction belt is
traveling.

B) Having observed belt and determined tracking problem, follow procedures
in "How to Steer The Belt", See Figure 7B.
HOW TO STEER THE BELT
Condition 1. . .When the belt is running in the direction (FLOW) with the
arrow, but tracking (drifting) towards Side "X", move the Snub Idler nearest
the INFEED end of Side "Y" towards the DISCHARGE end of the conveyor.
Condition 2. . . When the belt is running in the direction (FLOW) with the
arrow, but tracking (drifting) towards Side "Y", move the Snub Idler nearest
the INFEED end of Side "X" towards the DISCHARGE end of the conveyor.
If Belt Direction (FLOW) is reversed, all the above conditions will remain the
same as in Figure 7B, except you are now viewing the conveyor from the
opposite end.
If belt continues to track improperly, re-check all items covered in "Pre-
Tracking Inspection" and make corrections as necessary.
NOTE: In all conditions, you are viewing the Conveyor Belt from the INFEED end.
All corrections will be made from the INFEED end of conveyor.
