CORRECTIVE ACTION Continued
2.
Remove left- and center-front air inlet grilles (see WP 0342 00). Inspect power takeoff coupling to see
that drive shaft is firmly attached to power takeoff coupling. Tighten bolts and/or replace missing bolts
WARNING
Keep hands and arms away from fan blade and drive while engine is running, or serious injury to
personnel will result.
3.
Have assistant start engine. Observe power takeoff coupling and drive shaft. If they are not turning,
remove powerplant (see WP 0098 00). Tighten power takeoff retaining nut. Torque nut to 240250
lb-ft (16551724 Nm) and go to step 4.
4.
Remove hydraulic line intermediate rear right center floor plate (see WP 0296 00). Remove pipe plug
from mechanical transmission and install pressure gage (item 31, WP 0490 00). Operate engine at 1600
rpm. Lubricating oil pressure should be 1019 psi (69131 kPa). If lubricating oil pressure is 1019
psi (69131 kPa), go to step 5. If lubricating oil pressure is not 1019 psi (69131 kPa), notify Direct
Support Maintenance.
5.
Disconnect hydraulic line. Install tee and pressure gage (item 31, WP 0490 00). Connect hydraulic line.
Operate engine at 1600 rpm. Mechanical transmission clutch operating pressure should be 140225
psi (9651551 kPa). If clutch pressure is 140225 psi (9651551 kPa), go to step 6. If clutch pressure
is not 140225 psi (9651551 kPa), notify Direct Support Maintenance.
6.
Inspect hydraulic lines and connections for damage and leaks. Replace hydraulic lines and connections
that show signs of damage. Tighten connections that leak. If leaks persist, notify Direct Support
Maintenance.
7.
Inspect hydraulic components (valves, pumps, cylinders, etc.) for leaks at gaskets and/or seals. Tighten
loose covers, plates, and housings. If leaks persist, notify Direct Support Maintenance.
