Installing a Focal® Retarder
Focal ® retarders are designed to be adapted at the gearbox output or at the transmission axle input. All adaptations offered by Telma have been carefully reviewed and validated by manufacturers of related transmission parts.
Mounting to the gearbox or to the vehicle's axle
Specifically designed for short wheelbase tractors and rear engine buses, Focal ® retarders are attached to the flange of the gearbox output shaft or directly mounted to the axle.
