WINDSHIELD WASHER
Operation
The windshield washer, mounted on the right side of
the hydraulic components cabinet behind the cab,
has a 3.8 liter (1 gal) plastic reservoir (1, Figure 3-4)
with a 24 volt electric pump (2).
The washer is controlled by the windshield wiper
switch mounted on the turn signal lever. When the
switch is activated, washing solution is pumped
through the outlet hose (3) and fed to a jet located in
each of the windshield wiper arms.
Service
If windshield washer maintenance is required, check
the strainer opening for obstructions and inspect the
hoses for damage. Check the voltage to the pump
from the control switch. If the pump is inoperable,
replace it with a new pump assembly.
Note: The pump is only available as an assembly
and cannot be repaired.
