Probable Cause: Inaccurate tensioner roller alignment or damaged camshaft and/or crankshaft gear.
External manifestation of a malfunction / breakdown / problem: Wear on one of the edges of the belt.
Probable Cause: Marks on the pulley indicate belt twitching while the engine is running. This could be due to a loose timing belt, misalignment of the rollers, or contact with any part of the drive.
External manifestation of a malfunction / breakdown / problem: The belt is cut into two parts.
Probable Cause: Foreign body in the timing system or excessive belt tension, which can also lead to bearing failure.
External manifestation of a malfunction / breakdown / problem: Belt break.
Probable Cause: Foreign body in the drive system, excessive belt tension, or belt kink at the break due to improper handling. Sudden breakage of the belt is usually caused by its bending at the point of failure due to improper handling.
External manifestation of a malfunction / breakdown / problem: The presence of fibers between the teeth.
Probable Cause: The presence of fibers between the teeth is normal and does not indicate belt damage. This is due to the manufacturing process of the timing belt and is observed at the junction of the threads.
External manifestation of a malfunction / breakdown / problem: Damage to one of the edges of the belt.
Probable Cause: Pulley misalignment or damage to camshaft and/or crankshaft gear.
External manifestation of a malfunction / breakdown / problem: Damage to the belt; peeling of several teeth.
Probable Cause: The cause may be a loose belt tension, contact with any part of the drive, or misalignment of the pulleys. With a high mileage of the car, the likelihood of this damage increases due to the non-parallelism of the pulleys.
External manifestation of a malfunction / breakdown / problem: Teeth are cut.
Probable cause: Insufficient belt tension.
External manifestation of a malfunction / breakdown / problem: Tears on the teeth.
Probable cause: Weak belt tension. The belt should be installed on a cold engine, ensuring that all bolts are properly tightened.
External manifestation of malfunction / breakdown / problem: Sudden break of the belt.
Probable Cause: Foreign body in the timing system, timing belt overtensioned, or belt kinked due to mishandling. Severe damage to the belt most likely means a foreign body has entered the drive.
