Diagnostics
You can determine the part failure by indirect external signs.There are some difficulties in identifying the fixed roller malfunctions. The performance of the failed item is not always accompanied by a preliminary characteristic whistle.
Even experienced motorists often neglect inspection and replacement. Therefore, we strongly recommend regular scheduled replacements of the fixed roller.
Replacing the guide roller
Make it a habit to replace the fixed roller each time replacing the belt. It is generally recommended to change belts every 60-90 thousand kilometers. Do not neglect this rule: the price of replacing the fixed roller in the end will be much lower than the cost of the engine repair in the case of a broken belt.
You can replace the fixed roller on your own or entrust it to specialists.
