Guide Pulley

Guide / deflection roller moves the timing belt. Most cars need several deflection rollers. They are used to determine the route that the belt will take. With the help of guide / deflection roller it is possible to change the direction. However, it is possible to add stability to the entire system. Guide roles must fit the belt used. It is necessary to take this into consideration when buying spare car parts. Normally, guide rollers of other cars can not be used. 

Since the deflection /guide roller is under a strong mechanical loading, it is subject to relatively quick wear. Therefore, it is highly recommended to replace deflection rollers each time you change the timing belt. This is necessary if there are signs of wear on the belt tensioner. In this case, all parts of the timing belt system must have the same operation life. If the deflection roller breaks or bursts, the timing belt will malfunction. Since a crack of the timing belt can be the result of roller failure, this situation should be avoided whenever possible. It is necessary to follow the terms of replacement to minimize the probability of failure.

The installation of a deflection / guide roller is not difficult, but only on a good car mechanic can replace the timing belt. A non-specialist can easily cause more damage. In addition, a special instrument is needed. Do you want to purchase car parts?

How to detect malfunctions of the timing belt pulley?

Diagnostics of the timingbelt pulleyis very difficult, since its malfunction is not always accompanied by extraneous sounds. Usually, failure of the component is indicated by indirect symptoms.

Routine inspection and replacement of tensioner pulleys andidler pulleys of the timing beltmay be neglected by both novice and experienced drivers. However, to prevent failures of thetiming mechanism, the pulleys should be replaced at the intervals stated by the vehicle manufacturer.
