1. Unlock and open the engine cover (1).
2. If the vehicle has dual batteries, disconnect both
negative battery cables (2 and 3) from both
batteries.
To access the lower battery (4), loosen the knob (5)
far enough so that the lip (6) on the upper battery box
clears the knob. Lift up the upper battery box (7) and
swing it out, so that the box clears the hydraulic tank
support bracket, to gain access to the lower negative
battery cable (2). Disconnect the lower negative
battery cable.
3. Remove the skylight wiper arm (8) from the skylight
wiper motor shaft (9).
4. Disconnect the washer hose (10) from the top hose
fitting (11).

flat washers (13) and acorn nut (14) from the tab on
the plastic case of the skylight wiper motor (15).
6. From the top of the cab, remove the nut (16) from the
wiper motor shaft (9).
7. From inside the cab, carefully pull the plastic
case (15), with the wiper motor inside, away from the
roof. Make sure that the rubber grommet (17) and
metal washer (18), from between the top plastic
cover and the roof, comes along with the plastic
case. Save all hardware for later re-assembly.
