An Extra Step
While
you’re
checking
the
sight glass, pay special attention
to the
color
of the Fuid. ±luid
that
is
milky
is
probably
contaminated
with
water.
Let
your mechanic know right away
since contaminated Fuid will ruin
the seals.
Step 2
Open the access door all the
way before checking the Fuid
level. When the door is only
partially open, you’ll get a high
reading
because
the
hydraulic
cylinders aren’t fully extended.
Later,
when
you
drain
extra
±RH from the reservoir to bring
down the level, the system is
under-²lled. That lets air into the
system and may keep the door
from opening.
Open the access door to the
fourth detent on the support link.
That’s fully open.
Step 1
Park the vehicle on level ground. The reservoir sight glass won’t give an accurate
reading if your Bradley is parked at an angle.
Step 3
Eyeball the Fuid level in the reservoir. The
level in the sight glass should reach the full
mark line inscribed on the reservoir.
If it doesn’t, add ±RH until it reaches the
line. If the level passes the mark, drain some
of the Fuid. Use an AOAP vampire pump,
NSN
to
remove
the
excess Fuid.

then you shouldn’t
be surprised if you
have to open the door

next time.
checking the
reservoir level
is a
daily
task.
I
hate
