Dayco Hydraulic Timing Belt Actuator

The Dayco Hydraulic Timing Belt Actuator, also called a hydraulic timing belt tensioner, absorbs changes in timing belt tension. Tension can change with engine temperature, engine speed, or general wear and aging of the belt. It is part of Dayco's timing drive tensioner and pulley range for the aftermarket.

Key Features:

• Absorbs changes in timing belt tension
• Keeps tension on the timing belt constant throughout crankshaft revolution
• Helps reduce noise and prevents belt flapping
• Supports proper transmission efficiency over the service life of the belt
• Built for durable, long-lasting service

Dayco is an established name in timing drive and belt systems. A hydraulic tensioner that works correctly helps protect the timing belt and keeps the engine's timing drive running smoothly. Replacing a worn or leaking actuator when you replace the timing belt is a common maintenance practice.
