Process of Compound Pulley

Mold

The first step in the production process is creating the mold that will shape the pulley.

Casting

Once the mold is ready, molten metal is poured into it to form the pulley.

Raw materials

High-quality raw materials are used to ensure durability and performance.

Production

The pulley is manufactured with precision and attention to detail.

Testing

Each pulley undergoes rigorous testing to meet quality standards.

Antirust treatment

A special coating is applied to prevent corrosion and rusting.

Seperate inspection

Each pulley is individually inspected for quality assurance.

Marking

Finally, the pulley is marked with necessary information for identification.

What is the function of the tensioner and idler pulley?

• Maintains proper tension on the drive belt
• Guides the belt along the pulley system
• Reduces wear and tear on the belt
• Prevents slippage or misalignment
• Ensures smooth operation of engine components

How to stop a idler pulley from squeaking

• Regularly lubricate the pulley
• Check for any debris or obstructions
• Inspect for signs of wear or damage
• Adjust tension on the drive belt if necessary
• Replace the pulley if squeaking persists
