D
rivers, when the day’s over and you’re
parking your Stryker in the motorpool,
make sure you shut off power to the
driver’s vision enhancer (DVE).
If you forget, a power surge at the
next startup could damage the DVE
camera, NSN 5855-01-525-1631, or the
DVE screen, NSN 5980-01-525-1688.
If that happens, you’re looking at a
hefty bill. A new camera costs almost
$11,000. A new screen will set your unit
back more than $3,600.
Engine Oil
Some drivers fgure as long as they keep the OBOE flled, there’s no need to
check the engine oil. Wrong!
Sure, a Full OBOE will replenish that burned-oFF engine oil. But that doesn’t
mean you couldn’t have a leak or oil contamination. And the only way to know is to
check the engine oil!
Always make sure your Stryker is on level ground beFore checking the engine
oil level. Also, the engine must be shut down at least 20 minutes beFore you pull
the dipstick.
The oil level should be in the
crosshatched area oF the dipstick.
Look For whitish blobs that indicate
water contamination. Take a sniFF,
too. That’s the best way to tell iF the
oil is contaminated with Fuel.
While you’re checking the oil
level, take a close look at the dipstick
tube For cracks or leaks. Oil overfll,
discolored oil, or a cracked dipstick
tube deadlines the vehicle.
OBOE
The on board oil exchanger (OBOE) is just what it sounds like—an oil exchange
system. Every 10 hours oF operation, the OBOE takes approximately 1/4-gal oF oil
From the engine and injects it into the Fuel system where it’s burned oFF.
The OBOE then replaces that engine oil From its 1.71-gal reservoir. When Full,
the OBOE can continue to replace the burned-oFF engine oil For about 60 hours
beFore running dry.
When empty, the OBOE continues
drawing oil From the engine For burn-
oFF. Eventually there’s not enough
oil For the engine and it burns up!
There are three sight glasses on
the side oF the OBOE—one at the
top, one in the middle, and one near
the bottom. IF you see oil in the top
sight glass, you’re good to go. IF
you can’t see oil in the bottom sight
glass, the OBOE is
WAY
overdue
For a fll-up.
