This LO is for operator/crew (C) or unit (O) maintenance. Lube intervals (on-condition or hard time) are based on normal
operation. Lube during constant use, and less during inactive periods. The task-hour specified is the time you need to do
all the services prescribed for a particular interval. Use correct grade of lubricant for seal temperature expected.
For equipment under manufacturers warranty, hard time oil service intervals shall be followed. Intervals shall be short-
ened if lubricants are known to be contaminated or if operation is under adverse conditions (such as longer than usual
operating hours, extended idling periods, extreme dust).
Chemical feed pump and R.O. pump oils must be sampled at 100 hour intervals as prescribed by TB 43-106. On-
condition (OC) oil sample intervals shall be applied unless changed by the Army Oil Analysis Program (AOAP) laboratory.
Ensure ROWPU is level before checking oil levels in chemical feed pump and R.O. pump. Drain oils while they are warm.
Lubricate trailer immediately after fording, or as soon after unit movement permits. Dry equipment before lubricating.
On the picture, a dashed line (--) means there are lubrication points on both sides of the equipment.
