brake rod do not line up, adjust brake. Check adjustment on brake air valve linkage (see WP 0265 00)
and adjust if required.
3.
Open rear exhaust deflector doors and transmission access doors. With brakes released, check to see
that each brake-supply-and-slack-adjustment lever (right and left) is touching the respective stops. If
brake-supply-and-slack-adjustment levers do not touch their respective stops, adjust brake linkage (see
WP 0365 00).
4.
With brakes properly adjusted, have assistant apply and release brakes several times. Observe each
time that both right and left brake-supply-and-slack-adjustment levers return to their respective stops.
If brakes do not fully release each time, check linkages and repair or replace any binding, bent, or
broken parts.

Remove left- and center-front air inlet grilles (see WP 0342 00). Disconnect one end of the throttle rod
(see WP 0363 00). Have an assistant depress accelerator pedal to its maximum. Depress accelerator
linkage on front of engine to its maximum. If a free pin cannot be made, check linkage and repair or
replace any binding, bent, or broken parts. Check throttle linkage adjustment (see WP 0363 00). If a
free pin fit can be made, notify Direct Support Maintenance.

Turn MASTER switch to OFF position. Remove fuel line connected to in port on purge pump. Place
fuel line in a container and turn MASTER switch to on position. If no fuel flows from disconnected
fuel lines, troubleshoot electric fuel pump (see WP 0047 00).
8.
If fuel flows into container, turn MASTER switch to OFF position and connect fuel line. Disconnect
fuel line from out side of purge pump. Place a container under purge pump, turn MASTER switch to
on position and operate purge pump. If no fuel flows from purge pump, turn MASTER switch to OFF
position. Replace purge pump (see WP 0122 00).
9.
Remove front air inlet grilles (see WP 0342 00). Unscrew fuel outlet hose at main engine fuel check
valve (see WP 0126 00). Disconnect main engine fuel hose at primary fuel filter (see WP 0127 00).
Operate purge pump with MASTER and fuel pump switches in ON position. If no back pressure or
only light back pressure can be felt during operation, replace main engine fuel check valve (see WP
10. Remove front air inlet grilles (see WP 0342 00). Check primer hose and fuel return hose for proper
