hecking the differential bolts on your Stryker is a before- and after-operation
PMCS check, drivers.
And it’s an important one. Heat, vibration, and collisions with brush, rocks
and other debris can be a real bolt buster. And that’s enough to make you lose a
differential.
Each differential has eight bolts, nuts and washers holding it in place. Each vehicle
has four differentials, so you have 32 sets of hardware to check.
W
hen retrieving the bridge on your AVLB, you don’t want
anything
in the way.
‘Cause if it is, it’s
gonna get crushed!
Unfortunately,
some
drivers
are
forgetting to remove
the
AS-1729
whip
antenna, NSN 5985-
00-985-9024, before
retrieving the bridge.
That antenna has a
lot of spring in it, but
not enough to recover
after being crushed
by the bridge.
So
remember
to
remove the antenna
before
recovering
the
bridge
like
it
says in Step 31 on
Page 0020-7 of TM
5-5420-202-10 (Dec
09). Then reinstall it
after the bridge is in
place.
Look for shiny spots around the nuts and washers that indicate loosening bolts. If
you see a shiny spot, report it.
Mechanics, add a few drops of sealing compound, NSN 8030-01-014-5869, to
the bolt threads before torquing the nuts to 58-64 lb-ft. That’ll help keep the nuts in
place.
Replace missing bolts with NSN 5305-01-297-1865. A new nut comes with NSN
5310-01-155-3858 and a new washer with NSN 5310-01-265-6333.
While you’re checking the bolts during after-operation PMCS, don’t forget to take
a quick look at the differential oil sight glass. The oil level should be 3/4 full in the
sight glass.
If it’s low, remove the Fll plug and add gear oil, NSN 9150-01-363-1192, until it
reaches the bottom lip of the Fll port.
