3406, 3408 and 3412 Engines In Most Applications
Description of Change: A stronger suction bell assembly is now used in the engine oil lines group on 3406, 3408 and 3412 Engines in most applications. The new suction bell has more welds in a larger area to make the assembly more rigid. For this reason the new suction bell will give longer service life than the former suction bell.
Adaptable As: Direct replacement.
