Table 8. Tophandler System Troubleshooting Procedures (Non-Error Code).
MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1. Tophandler Will Not Tilt Forward or
Rearward Properly.
1. Access maintenance ECS
display and check for active
hydraulic or electrical system
error codes (WP 0004 00).
2. Inspect
tophandler
tilt
cylinders for obstructions,
damage, and signs of leakage.
a. Remove any obstructions.
b. Notify DS Maintenance to
replace damaged or leaking
tophandler tilt cylinder(s).
3. Check tilt cylinder hydraulic
lines and hoses for damage and
signs of leakage.
a. Tighten loose connections.
b. Replace damaged or leaking
lines and hoses (WP 0180 00).
4. Test tophandler operating
pressure (WP 0186 00, test
point no. 11). Operating
pressure should be 3045 psi
(210 bar).
Notify DS Maintenance to
replace and adjust tophandler and
steering pump assembly if
pressure is not as specified.
5. Check
tophandler
tilt
calibration settings (WP 0197
00).
Calibrate tophandler as required
(WP 0197 00).
2. Tophandler Will Not Oscillate (Level)
Properly.
1. Access maintenance ECS
display and check for active
hydraulic or electrical system
error codes (WP 0004 00).
Perform troubleshooting pro-
cedures to clear diagnostic
code(s) (WP 0005 00).
2. Inspect tophandler leveling
cylinders for obstructions,
damage, and signs of leakage.
a. Remove any obstructions.
b. Notify DS Maintenance to
replace damaged or leaking
leveling cylinder(s).
3. Check tophandler leveling
cylinder hydraulic lines and
hoses for damage and signs of
leakage.
a. Tighten loose connections.
b. Replace damaged or leaking
lines and hoses (WP 0181 00).
4. Inspect
wear
plates
for
excessive wear and damage.
Replace excessively worn or
damaged wear plates (WP 0140
00).
5. Test tophandler operating
pressure (WP 0186 00, test
point no. 11). Operating
pressure should be 3045 psi
(210 bar).
Notify DS Maintenance to
replace and adjust tophandler and
steering
hydraulic
pump
assembly if pressure is not as
specified.
