New Manual Brakesaver Control Group
Usage:
3408 Truck Engines
Description of Change: A new manual Brake-Saver control group is available for 3408 Truck Engines. The new group operates on 380 kPa (55 psi) air pressure at the control valve. The former group operated on 345 kPa (50 psi) air pressure. The increased pressure will give better operation of the BrakeSaver on these engines.
Adaptable As: The new 9N2642 Control Group is a direct replacement for the former 9N574 Control Group in this application. The 9N574 Control Group is still used with the 3406 Truck Engine.
