Usage:
3306B ATAAC Truck Engines
Description of Change: A new piston body assembly is used in 3306B ATAAC Truck Engines. The new piston body assembly produces a higher compression ratio than the former piston body assembly. The higher compression ratio will help reduce the duration of white smoke from the exhaust during cold weather starts. Cold weather starting aids such as jacket water heaters, fuel heaters, cetane improvers, and ether starting aids are also recommended for minimizing white smoke during cold weather starts and during the warm up period.
Adaptable As: The new 9Y8217 Piston Body Assembly is a direct replacement for the former 8N3102 Piston Body Assembly in 3306B ATAAC Truck Engines, when all six of the former pistons are replaced together.
