Introduction

The ADB-120-E4-HT from HUEGLI-TECH / Governor America Corp. is a linear, proportional, electric fuel metering servo for use on Cummins engines with PT fuel systems. The actuator is energized by signals from a speed control unit and is capable of delivering fuel at rates up to 770 kg/h (1700 lbs/h).

Installation

The actuator must be rigidly mounted as close as possible to the outlet of the PT pump. GAC bracket BK-115-E4-HT is designed to fit the ADB-120-E4-HT to most Cummins engines. Attach the actuator bracket to the engine. Attach the actuator to the bracket with ¼-20 1” screws, washers and nuts. The actuator to valve linkage is set at the factory and requires no adjustment. Connect the valve to the fuel system as shown in Diagram 1. All fuel line connections can be made using either steel tubing or wire braided rubber hose. All engines require 8 mm (5/16”) ID tubing except12 and 16 cylinder engines which require 9.5 mm (3/8”) ID tubing.
