Installation of hydraulic oil pump is the reverse of the removal procedure with attention given to the following points:
Always replace hoses with appropriate parts to prevent hoses from bursting. Failure to comply may
result in injury or death to personnel.
Cleanliness is essential for correct and safe operation of the hydraulic system. Ensure dirt and debris
are not allowed to enter hydraulic system. Failure to comply may result in damage to equipment.
· Ensure all hoses and tubes are reconnected to positions noted prior to removal.
· Install cable ties as necessary.
Ensure pump is clean and free from foreign matter by wiping with a clean cloth.
Place new gasket on hydraulic pump.
Ensure new lockwashers are used and tighten all nuts to 190 lbf/ft (258 N·m).
c. New Pump Startup Procedure.
To avoid damage to hydraulic pump, do not run for more than 5 seconds if cavitation is heard. Failure
to comply may result in damage to equipment. If cavitation is heard, shut OFF hydraulic system, wait
30 seconds, and restart system.
Start engine and listen for unusual sounds (TM 5-2420-230-10). If unusual sounds or vibrations are noticed, shut OFF
engine and investigate to determine cause.
