C.A.T. under drive fluid damper pulley kits are exclusively designed and specially manufactured by our engineering expertise; the fluid damper pullet kits are patented in the U.S. and worldwide. The main housings and crankshaft hubs are precision forged from 1020 low carbon steel. The water pump pulleys are extruded from 6061 aluminum alloys with T-6 heat treatment. The high viscosity silicone fluid and inertia ring absorbs the torsion vibration from the rotating assembly at any frequency and RPM. All C.A.T. pulley fluid damper kits are tested and certified in compliance with SFI 18.1 specification. |
