LUBRICATION INSTRUCTIONS
GENERAL
The lubrication instructions include table 1, Lubrication Specifications and table 2, Lubrication Intervals
and Locations. Table 2 is used for lubricating the boat under normal operating conditions.
SERVICE INTERVALS
Service intervals are for normal operation of the boat in moderate temperatures, humidity, and atmospheric
conditions. The intervals are hard-time intervals performed in accordance with the boat's age, calendar, or
operating time. The hard-time intervals in table 2 are based on hour and calendar times. An example of
hour usage and calendar intervals is 250/Q; 250 stands for 250 hours of operation, and Q stands for
quarterly (every three months). The lubrication for the boat is to be performed at whichever interval occurs
first.
Hard-time oil service intervals must be followed for equipment under manufacturer's warranty. Hard-time
intervals may be shortened if lubricants are known to be contaminated or operation is under adverse
conditions, including longer than usual operating hours, extended idling periods, or extreme dust. Hard-time
intervals may be extended during periods of low activity, although adequate preservation precautions must
be taken.
Service intervals under abnormal conditions will increase the frequency of lubricating service, such as high
or low temperatures, or extended operations. These conditions can diminish a lubricant's protective quality.
ARCTIC CONDITIONS
Refer to FM 9-207, Operation and Maintenance of Ordnance Materiel in Cold Weather 0 to -65 F
(-18 to -54 C), or table 1, Lubrication Specifications.
CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army material is a continuing concern. It is important that
corrosion problems are reported so that corrections and improvements can be made to prevent future
problems.
While corrosion is typically associated with rusting of metals, it can also include deterioration of other
materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials
may be a corrosion problem.
If a corrosion problem is identified, it can be reported using Standard Form 368, Product Quality Deficiency
Report. Use of key words such as corrosion, rust, deterioration, or cracking will ensure that the information
is identified as a CPC problem. This form should be submitted to the address specified in DA Pam 750-8.
