436-6512 Belt Tensioner
Cat® Belt Tensioner for Alternators
Description
The belt tensioner is a component used to keep the alternator belt at the proper tension. The belt transfers power from the engine to the alternator, enabling the alternator to generate electricity to power the electrical components of the Cat machine. The tensioner usually consists of a spring-loaded arm attached to the block. The arm is positioned to press firmly against the alternator belt, keeping it properly aligned and tensioned.
Features
- Ensures the belt stays properly aligned.
- Reduces belt wear by maintaining proper tension.
Applications
The belt tensioner is used to prevent power loss by applying a constant force to the belt.
