LCX viscous fan drives

A durable, live-center fan drive with industry-leading low-speed controllability, low off speed and Cold-Start Disengagement (CSD™) technology. Engineered for heavy-duty trucks and off-highway applications.

Faster and quieter engine starts
— Cold-Start Disengagement technology prevents immediate fan drive engagement upon start up allowing faster and quieter engine and cab warmup.

Maximum fuel efficiency and available engine horsepower with less noise
— Fully-variable operation cools engine only as needed thereby reducing noise and parasitic loss while maximizing fuel efficiency.

Maximum uptime and long life
— Maintenance-free
— High-quality bearings and durable design.

Applications

  • Agricultural tractors
  • Industrial crane trucks
  • Backhoe loaders
  • Excavators
  • Other construction equipment
  • Generator sets
  • Heavy-duty trucks
  • Medium-duty trucks
  • Vocational trucks
  • Buses
  • Specialty on-highway vehicles
  • Variety of off-highway equipment

Featuring Innovative Technologies from Horton
Cold-Start Disengagement (CSD™)
— Unique reservoir design minimizes latent fluid in the shear plates to prevent engagement at startup, reducing noise and enhancing engine and cab warmup — particularly in cold weather
— Helps engines meet emissions regulations.

Low-speed controllability
— Best-in-class, low-speed controllability offers more precise fan control across all speeds, increasing fuel economy, reducing noise and maximizing available horsepower with smooth modulation.
