Overview
The hydraulic tensioner maintains the belt tension to minimize the slip and vibration and provides
long life span of the belt. Hydraulic tensioner consists of hydraulic tension spring, hydraulic
damper, lever arm and tension pulley.
To transfer the tension to the belt from the hydraulic tensioner in small working space in G20DF
engine, the belt system uses the longer lever arm.
