Chain Checklist
Check chain for:
(1) Elongation Due to Joint Wear - Chain is worn when it has lengthened 5%.
Elevator Conveyor chain pitch - 4.25” (108 mm).
............................................ 10 links x 4.25” (108 mm) pitch + 5% wear = 44.63” (1134 mm).
Discharge Conveyor chain pitch - 3.25” (83 mm).
............................................ 10 links x 3.25” (83 mm) pitch + 5% wear = 34.13” (867 mm).
(2) Stiff Joints - Drag chain rollers packed with debris which leads to a torsion failure of the pins.
(3) Sidebar Wear - Inside of links worn from sides of sprocket teeth indicating misalignment.
(4) Sidebar Wear - Check drag chain sidebars on bottom side to see if they are worn (or bent) from
contacting idler roller flanges.
(5) Roller Wear - Rollers should be polished where the sprocket tooth touches, not worn or gouged.
Worn or gouged barrels could indicate sprocket problems such as hooked teeth.
(6) Roller Wear - I.D.’s of rollers are worn if there is excessive play or misalignment.
(7) Obstructions - Check for any liner wear plates or joints that are loose or out of line which will
catch the chain slats as they pass by.
Slip and fall hazard.
Adjust chain tension while standing on a securely placed ladder. Never
climb onto top of machine to access adjusters.
