M a i n t e n a n c e L e v e l s . This lubrication order (LO) is for operator/crew and organizational maintenance. The lowest
level of maintenance authorized to lubricate a point is indicated by either operator/crew (C) or organizational (0).
Operator/Crew may lubricate points authorized for organizational when authorized by organizational.
Lube Intervals. Lube intervals (on-condition or hardtime) and related manhour times are based on normal
operation. The manhour time specified is the time needed to do all the services prescribed for a particular interval.
The calendar interval may be extended during periods of low activity. If extended, adequate preservation precautions
must be taken. Engine oil/transmission oil/hydraulic oil/steering oil must be sampled at 90-day intervals as prescribed
by DA Pam 738750. Hardtime intervals will be applied in the event AOAP laboratory support is not available. For
equipment under manufacturer's warranty, hardtime oil service intervals shall be followed. Intervals shall be
shortened if lubricants are known to be contaminated or if operation is under adverse conditions, such as
longerthanusual operating hours, extended idling periods, or extreme dust.
Intervals shown in this LO are based on calendar times or calendar times and mileage. An example of a calendar
lubrication interval is: S, in which S stands for semiannually (every six months). An example of a mileage and
calendar interval is: 9/A, in which 9 stands for 9,000 mi (14,481 km), and A stands for annual (every 12 months).
Perform the lubrication at whichever interval occurs first. Special lubrication intervals and services are shown by the
use of asterisk (*) symbols. Notes are located on card 32.1.
