The “camshaft pulley” also called “vernier pulley” or “camshaft toothed wheel” is an essential part of your engine distribution system. In fact, its role is to transmit the movement of the crankshaft through the timing belt (or timing chain) to your camshaft, thus it allows you to control the opening and closing of your valves. intake and exhaust.
Finally, its operating role serves to adjust your timing of your distribution as best as possible.

By fine-tuning the adjustment of your timing, this vernier pulley makes maximum efficiency and mechanical performance possible.

Generally, in order to increase the resistance of Cat Cams pulleys, they are treated by hard anodizing in order to obtain better longevity over time.

A camshaft pulley or Vernier pulley is a highly stressed part and undergoes enormous mechanical stress during sporty, intense use or in automobile competition, as a result its teeth tend to wear out with time. You should therefore remember to check the wear of your pulley when changing your timing belt or chain.

Here are some signs of ACC pulley wear :

• abnormal engine noise
• poor functioning of the valves (significant noise)
• low engine power
• an engine malfunction (especially jerks at low revs)
