M88A2 Recovery Vehicle . . .
✺
The transmission oil filters, NSN
2940-01-434-5206, normally become
clogged after the first 150 hours of
use in a new vehicle.
When the hour meter on your
vehicle’s engine reaches that 150-
hour plateau, TACOM says you may
want to consider changing the
filters. Of course, you can
always wait until the clogged
filter indicator comes on.
Filter life should be
normal, approximately
750 operating hours,
after the first change.
✺
Taking off the main winch assembly housing, or nose piece, means removing
the 44 bolts that hold it in place.
Each bolt that is removed puts extra stress on the remaining ones. That extra
stress can snap or strip some of the bolts.
Make sure you use a lifting device—a wrecker or another M88—to support
the weight of the nose piece as you remove the bolts. That prevents shifting and
keeps bolts in
good shape.

✺
The first report you get back from the Army Oil Analysis Program
(AOAP) will most likely point out an abnormally high level of silicon
in the engine oil.
Don’t worry. There’s nothing wrong with the engine. That initial
high silicon level comes from
the manufacturing process
and is
not
unusual.
Just follow the
AOAP report
instructions and
change the oil
and filter.
The next sample
should be fine.
