RAPIDLY EMPLACED BRIDGE (REB)
NSN 5420-01-481-3959 P/N 12480471
This lubrication instruction is for field maintenance, and provides the lubrication requirements needed
to support the REB. Included are Fluid Capacities, Lubricant Requirements, Lubrication Intervals, and
Locations for lubricating the bridges and pallet.
Service intervals are for normal operation in moderate temperatures, humidity, and atmospheric
conditions. The intervals are hard-time intervals which are performed in accordance with the age of
bridge and pallet, calendar time, or usage such as operating hours. The hard-time intervals are
based on months of calendar times. An example of calendar intervals is: semiannually (every six
months), annually (every 12 months), or biannually (every 24 months). The lubrication for the
bridges and pallet is to be performed at whichever interval occurs first.
For equipment under manufacturer's warranty, hard-time oil service intervals shall be followed.
Hard-time intervals may be shortened if lubricants are used under adverse conditions, including
longer-than usual operating hours. Hard-time intervals may be extended during periods of low
activity, although adequate preservation precautions must be taken.
Lubricants are shown in table 1, and intervals and locations are shown in tables 2 and 3, and
figures 1 through 4.
CORROSION PREVENTION AND CONTROL (CPC)
Corrosion prevention and control (CPC) of Army materiel is a continuing concern. It is important
that corrosion problems are reported so they can be corrected 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
that the information is identified as a CPC problem.
The form should be submitted to the address specified in DA Pam 750-8.
Filter shall be changed and pre-filter cleaned as applicable when:
They are known to be contaminated or clogged.
Prescribed hard-time intervals are reached.
