T
he sight glass on each of your Stryker’s wheel hubs
makes it easy to check the oil level.
Unless you try to do it too early.
Oil levels in the wheel hubs should be checked after
operation—but not until about an hour has passed.
That allows the oil to run back from the planetary
gears into the hub so you get an accurate reading in
the sight glass.
Checking too soon will make you think the level is
low. Then, oil is added causing overF
lling. That can lead
to blown seals—a mess and lots of work.
The correct oil level should be between
3
/
4
and
7
/
8
full in the sight glass.
Without the cover,
wash water gets into
the engine air intake
and exhaust. When that
happens, you could
blow the pack.
So before you get
that hose, grab the
environmental cover
and secure it in place!

f the shackles are installed
with the retaining nut and
cotter pin facing inside, the
ramp could hit them as it’s
lowered.
To prevent the damage—
and the noise—make sure the
retaining nut and cotter pin
are installed facing away from
the ramp. Then double-check
the shackles as part of your
before-operation PMCS.
M1A1 AIM Tank RHNB
Use NSN 6110-01-514-7369 to order a redesigned hull networks box (RHNB) with container
(NSN 8115-01-509-8851) for your M1A1 AIM tank with embedded diagnostics. The NSN
listed as Item 1 in Fig 153 of TM 9-2350-264-24P-1 has the wrong supply class. Make sure
you use the container when returning an unserviceable RHNB to prevent damage during
transport. The RHNB, NSN 6110-01-517-1380, without a container is a terminal item, but
is still available until stock is depleted.
