10.8.5 Engine
Low Oil Pressure Sender
The engine low oil pressure light warns the
operator to discontinue forklift operation immedi-
ately because engine oil pressure is too low.
The engine low oil pressure light in the warning
lights gauge is described in paragraph 10.8.5.
The engine low oil pressure sender for this light (1)
is shown in Fig. 10.42.
The oil pressure warning bulb lights to warn the
operator to discontinue forklift operation immedi-
ately when engine oil pressure falls below 8.7 psi
(0,6 bar). Battery voltage is applied to one side of
the bulb and a ground path is provided by the
engine low oil pressure sender. The bulb will also
light momentarily due to low oil pressure when the
ignition key is turned to start the engine. After the
engine starts and builds normal oil pressure, the
sender opens and the light goes out.
a. Removal
1. Disconnect negative (–) cable (2, Fig. 10.38)
from the batteries.
2. Unlock and open right engine access door.
3. Tag and disconnect wire from terminal of low
oil pressure sender, Fig. 10.42.
4. Remove low oil pressure sender.
b. Disassembly
Do not disassemble the engine low oil pressure
sender.
c. Cleaning and Drying
Without submerging sender, clean sender as
required by using a fiber bristle brush and an
approved solvent.
d. Inspection and Replacement
1. Check engine oil level before testing sender.
Correct low oil level condition.
2. Test the sender for continuity while installed
on engine. With wire disconnected from
sender terminal, connect an ohmmeter or
continuity tester between the sender terminal
and a ground point. Continuity should be
present. Connect wire to terminal on sender
and start the forklift. If warning light remains
ON after pressure has built up in the engine,
the sender is defective.
3. Replace the sender if it fails to pass the tests
in step 2.
e. Installation
1. Install low oil pressure sender.
2. Connect wire to terminal of low oil pressure
sender.
3. Connect negative (–) cable (2, Fig. 10.38) to
batteries.
4. Start engine and inspect installation for oil
leaks.
5. Close and lock right engine access door.
