Leak Detector Float Sensor
The leak detector float sensor closely monitors the hy-
draulic fluidlevel in themain hydraulictank. The sensor
contactsareopenwhenthe floatisintheraisedposition
and oil level in the hydraulic tank is correct. The sensor
closes when the float is in the lowered position caused
by a low oil level and potential oil leak.
NOTE: Forinformationonleakdetector operationrefer

this chapter.
Testing
1. If the float sensor is connected to the main harness,
removehydraulictankcap andscreen fromfillerneckof
hydraulic tank. Turn ignition switch to the RUN position
(donotstarttheengine).Insertacleanrodorscrewdriv-
er into filler neck and gently push down on sensor float
(Fig. 33). Alarm should sound after a one (1) second
time delay.
2. If the float sensor is removed or disconnected from
themainharness,connectacontinuitytesteracrossthe
float sensor wire terminals. There should be continuity
acrosstheterminalsonlywhenthefloatispusheddown.
There should be no continuity across the terminals
when the float is in the raised position.
3. If oillevelsensor wasremovedfrom reservoir,install
oil levelsensor into reservoir makingsure thatarrowon
sensor is pointing down (Fig. 34). Torque sensor nut
from 110to140in--lb(12.5to15.8N--m).
4. Aftertesting,makesurethathydraulicoillevelinres-
ervoir is correct.
