Maintenance Procedures
Sprockets - Elevator/Discharge Conveyor - Inspect
Check sprockets for:
• Hooked Teeth - Worn teeth will over-stress chain and cause chain to snap in and out of
sprocket and possibly hang up when exiting.
• Build-Up in Pockets - Material packed in the pockets will cause chain to stretch.
• Teeth Scrubbed On Sides - Indicates misalignment of sprockets and shafts. Chain could also
be worn to the point it won’t track properly.
• Chain Rides High On Teeth - Chain is elongated and close to needing replacement.
• Chain Too Tight - Indicates material packed in pockets or chain over-tensioned.
• Noise - Chain should make a clicking sound (metal on metal) as it engages the sprocket. If it is
snapping or popping, check for hooked teeth or stretched chain.
1. Inspect sprocket teeth (1) for wear.
NOTICE: Replace both sprockets as a pair when wear
exceeds 0.13" (3 mm). Failure to replace excessively worn
sprockets may result in premature chain wear or
damage. If chain is worn, replace chain to prevent
premature wear of new sprockets.
2. Check for loose or missing sprocket mounting bolts
(2). Tighten or replace any loose or missing bolts.
WARNING
Contact with moving conveyor belt and rollers can crush or cut.
Stay away from moving conveyor. Turn conveyor and engine off before
inspecting, adjusting, cleaning, unplugging, or servicing conveyor.
