Possible cause: Inaccurate alignment of the tensioner rollers or damage to the camshaft and/or crankshaft gear.
External manifestation of malfunction/breakdown/problem: Wear of one of the edges of the belt.
Probable Cause: Marks on the pulley indicate that the belt is jerking while the engine is running. The cause may be weak timing belt tension, incorrect alignment of the rollers, or contact with any part of the drive.
External manifestation of malfunction/breakdown/problem: The belt is cut into two parts.
Possible cause: A foreign object has entered the timing drive system or the belt is too tight, which can also cause bearing failure.
External manifestation of malfunction/breakdown/problem: Belt breakage.
Probable Cause: Foreign object in drive system, belt over-tensioned, or belt kinked at break due to improper handling. A sudden break in a belt is usually caused by it being bent at the point of failure due to improper handling.
External manifestation of malfunction/breakdown/problem: Presence of fibers between the teeth.
Possible Cause: The presence of fibers between the teeth is completely normal and does not indicate belt damage. This is due to the timing belt manufacturing process and is observed at the thread connections.
External manifestation of malfunction/breakdown/problem: Damage to one of the edges of the belt.
Possible cause: Pulleys not parallel or damage to camshaft and/or crankshaft gear.
External manifestation of malfunction/breakdown/problem: Belt damage; peeling of several teeth.
Possible Cause: Possible cause may be poor belt tension, contact with any part of the drive, or pulleys not being parallel. With high mileage of the vehicle, the probability of this damage occurring increases due to non-parallelism of the pulleys.
External manifestation of malfunction/breakdown/problem: Teeth are cut off.
Probable cause: Insufficient belt tension.
External manifestation of malfunction/breakdown/problem: Breakouts on teeth.
Probable cause: Weak belt tension. The belt should be installed on a cold engine, ensuring all bolts are properly tightened.
External manifestation of malfunction/breakdown/problem: Sudden belt breakage.
Possible Cause: Foreign object in timing system, timing belt over-tensioned, or belt bent due to improper handling. Severe damage to the belt most likely means that a foreign object has entered the drive.
