Note position of actuator leads (black and white) at terminals (1 and 2,
Figure 11) so that they may be reconnected properly.
Disconnect actuator leads.
Disconnect ball joint (5, Fig. 9) from actuator level (4). If actuator
adjustment is correct, or near to correct, the lever will remain in IDLE
position as indicated in Fig. 9.
Check oil pressure and internal components of actuator by manually
forcing the actuator lever downward, out of IDLE position.
If pressure
and internal parts are normal, the actuator lever wil I resist manual
actuation.
If no resistance is felt, the actuator is either not receiving sufficient
fue I oil pressure or is internally defective. Replace actuator or restore
pressure.
Loosen locknut (4, Fig. 11). Install a 5/32-inch Allen wrench in the
socket-head adiusting screw (3).
NOTE: 1. Prevent the actuator pilot valve bushing (5) from turning
while loosening or tightening nut (4), or adjusting screw
(3), by placing an open-end wrench across flats on the
bushing .
2. If fuel oil pressure and actuator are normal, l/4 turn of
screw (3) will cause the lever (4, Fig. 9) to move from
one limit of its ful I trave I range (30 degrees) to the other.
Turning the screw (3, Fig. 11) CLOCKWISE (in) will
cause the lever to move downward to FULL FUEL position.
Turning the screw COUNTERCLOCKWISE will cause the
lever to move upward to IDLE position.
(9) Turn the adjusting screw (3, Fig. 11) as required to make certain it will
cause the actuator lever to move through its full range, back-and-forth.
In FULL FILL position it will be pointing downward at an angle of approx-
imate ly 10 degrees from horizontal.
Adjust screw (3) to place the lever
in this FULL FUEL position,
then turn the adjusting screw slowly COUNTER-
CLOCKWISE (out) until the lever gradually reaches IDLE position (see
Fig. 9). Stop turning the screw as soon as the lever reaches the end of
its travel into IDLE position. Tighten locknut (4). At this point, a
"rough" adjustment of the actuator has been completed.
Reconnect leads to actuator terminals (1 and 2, Fig. 11) in their original
.pos.if.ions,.. -
