There are some preliminary troubleshooting procedures that you must accomplish
prior to troubleshooting the conveyor assembly:
o Ensure the vehicle MASTER switch is in the ON position.
o Ensure the APU is operating the primary hydraulic pump and the hydraulic
system selector valve is pushed IN, or the main engine is operating the
backup hydraulic pump and the hydraulic system selector valve is pulled OUT.
Test components must be capable of withstanding a working
pressure of 2000 psi. Also, NEVER tighten hydraulic lines
or fittings while the hydraulic system is pressurized.
Damage to tubes and fitting could result in personal
The gage should indicate between
100 and 300 psi (Fig. 27). If the pressure gage is not in the correct range,
you must troubleshoot the primary hydraulic system.
o Ensure the conveyor is fully deployed (TM 9-2350-267-10).
o Ensure the conveyor override safety switch is in the ON position.
o Check the flow control valve. If the flow control valve is closed, open the
valve and adjust the conveyor speed (Fig. 27).
