SECTION II. SOLENOID VALVE L102
6-3. GENERAL. Fuel transfer solenoid valve L102 is connected in series in the fuel line between the auxiliary fuel inlet
port and the fuel strainers. Solenoid valve L102 actuates to pass fuel whenever fuel transfer pump contactor K106 is
actuated. Fuel may enter the generator set only when the fuel transfer pump is operating. The valve is closed at all
other times to prevent fuel from siphoning into or out of the generator set.
6-4. SOLENOID VALVE L102 DISASSEMBLY. See Figure 6-2.
a.
Tag and disconnect wiring from solenoid valve L102.
b.
Remove retaining cap and clip (2) to separate nameplate (3), housing subassembly (4), coil (6), base plate (7),
and solenoid base subassembly (8).
c.
Unthread to remove bonnet (9) and bonnet gasket (10) from solenoid base subassembly (8).
d.
Remove screws (1) to separate body (14), body gasket (13), diaphragm-core assembly (12), and core spring (11)
from bonnet (10).
6-5. SOLENOID VALVE L102 REPAIR. See Figure 6-2. Repair of the valve is accomplished by replacement of worn
or damaged parts. A repair kit (FV-158-929, FSCM 04845) consisting of a bonnet gasket (9), core spring (11), diaphragm
core assembly (12), and body gasket (13) is available.
6-6. SOLENOID VALVE L102 ASSEMBLY. See Figure 6-2.
a.
Install core spring (11) in diaphragm-core assembly (12). Install body gasket (13) in body (14). Then install
diaphragm-core (12) and body (14) on bonnet (10) and secure with screws (1).
b.
Install bonnet gasket (10) in bonnet (9) and thread onto solenoid base subassembly (8).
c.
On solenoid base subassembly (8), install base plate (7), coil (6), spring wave washer (5), housing subassembly
(4), and nameplate (3), and secure with retaining cap and clip (2).
d.
Reconnect wiring to solenoid valve L102 as tagged and discard tags.
