DRIVE CHAIN AND SPROCKET TENSION
START-UP PROCEDURES
DRIVE CHAIN AND SPROCKET ALIGNMENT
Maintaining proper chain tension is
especially important. Again, a periodic
visual inspection is recommended to
ensure chain tension within a pre-deter-
mined operating range.
Remember, before any adjustments are
attempted, conveyor must be shut “OFF”
and power source locked out.
Before replacing chain guard cover, check
to see if drive chain is operating within
1/2” range (see above illustration). If unit
is out of tolerance, adjustment is necessary.
To adjust drive chain tension, tensioner bolt
located on reducer push plate should be
tightened (rotate clockwise) if chain tension
is loose. Tighten until proper operating
range is achieved. If chain tension is too
tight, loosen tensioner bolt (rotate counter-
clockwise) as required. When adjustment
is complete replace chain guard cover.
WARNING: Do not operate unit until
chain guard cover is replaced. Serious
operator or other personal injury could result
if protective guarding is not replaced.
WARNING: To check drive sprocket
tension, shut “OFF” and lock out power
source before any adjustments are attempt-
ed.
WARNING: To check drive sprocket
alignment, it is imperative that conveyor is
shut “OFF” and power source is locked out
before any adjustments are attempted.
Set up and maintenance of drive sprocket
and drive chain alignment is critical (on
curves or spurs with drive assembly). A
periodic visual inspection is recommended
to confirm alignment of drive components
(which includes both drive sprockets and
drive chain). Should set screws become
loose, drive sprockets are subject to
excessive wear and ultimately, to untimely
replacement.
To check drive sprocket alignment, it is
imperative that conveyor is shut “OFF”
and power source is locked out before
any adjustments are attempted. Remove
chain guard cover and place straight-edge
(see illustration above) across face of
both drive sprockets. If re-alignment is
necessary, loosen set screws and adjust
drive sprockets as required. Remember
to securely tighten set screws when align-
ment is complete.
Before replacing chain guard cover,
check drive chain tension as described
in following section, “Drive Chain and
Sprocket Tension.”
