Electric Actuator ACD175 Series
ACD175Series Electric Actuator
1.The 175 SERIES electric actuator is designed to mount directly on a Bosch P size fuel injection
pump, with a right hand, rack, in palce of the mechanical governor. When the 175 actuator is
installed on the fuel pump, an optimum performance, long life fuel control system results. An
external fuel shut off lever is provided to manually override the actuator's control. Also provided
is an adjustable internal maximum fuel limit.
2.The 175 Series Electric Actuator can control fuel pumps of up to 8 cylinders. The actuator was
designed with two isolated chambers. The upper chamber is wet with oil and contains the
connection to the fuel rack and an optional manual shut off mechanism. The sealed lower chamber
contains the electromagnetic components.
3.This design eliminates the possibility of magnetic particles or other oil contaminants interfering
with the operation of the electric actuator. Unreliable devices such as bellows and sliding seals are
not used so that no maintenance is required. The designed life of the actuator is typically longer
than that of the engine.
