PROBLEM
POSSIBLE CAUSES OF PROBLEM
SUGGESTED REMEDY
TROUBLE SHOOTING HINTS - FRACTURE PLATE Overloading Inspect the drive to determine the cause of
high load and eliminate
Or
Redesign drive for larger pitch chain
TROUBLE SHOOTING HINTS - BROKEN PINS Overloading Inspect the drive to determine the cause of
high load and eliminate
or
Redesign drive for larger pitch chain
TROUBLE SHOOTING HINTS Loading is greater than
pin’s dynamic capacity
Inspect the drive to determine the cause of
high load and eliminate
or
Redesign drive for larger pitch chain
TROUBLE SHOOTING HINTS Overloading Single pitch offset link is to be eliminated
Redesign drive using a higher capacity
chain
ROUBLE SHOOTING HINTS - FATIGUE FAILURE Loading is greater than
chain’s dynamic capacity
Single pitch offset link is to be eliminated
Redesign drive using a higher capacity
chain
ROUBLE SHOOTING HINTS - CRACKING Stress corrosion cracking Inspect the drive to determine the cause of
high load and eliminate
Select anti-corrosive chain
ROUBLE SHOOTING HINTS - BROKEN ROLLER Speed too high
Sprockets too small
Chain riding too high on
sprocket teeth
Replace chain, reduce speed
Use larger sprockets or possibly redesign
drive for small sprocket
ROUBLE SHOOTING HINTS - WORN CONTOUR Chain rubbing on casing,
guide or obstruction
Replace chain if 5% or more height worn
out
Inspect and redesign casing, guide and
eliminate interference
ROUBLE SHOOTING HINTS - PIN OR BUSHIN GALLING Speed or load too high
Inadequate lubrication
Reduce speed or load
Redesign drive for smaller pitch chain
Provide proper lubrication system
