New Crankshaft Damper Assembly For 3306 Vehicular Engines Gives Longer Service Life{1205}
Usage:
All 3306 Vehicular Engines, Except Those Used In D5 Tractors
Description of Change: A new crankshaft damper assembly is used on all 3306 Vehicular Engines, except for those engines used in D5 Tractors, to give longer service life. The new damper has an improved rubber compound that will prevent separation of the outer damper ring caused by heat and time.
Adaptable To: All earlier 3306 Vehicular Engines, except for those engines used in D5 Tractors. The new 7N9312 Damper Assembly is a direct replacement for the former 2P9584 Damper Assembly, which has been canceled.
