Keep Oil on the Level
On Board Oil Exchanger
Don’t stop with just the engine oil dipstick. You’ll also need to check the oil
level in the on board oil exchanger (OBOE) after operation.
The Stryker’s engine burns about 3 drops
of oil for every hour of operation. That oil
comes from the OBOE. If the oil in the
OBOE runs out, you start burning engine
oil. The Stryker automatically shuts down
when too much engine oil is burned.
There are two sight glasses on the side of
the OBOE. 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 well
overdue for a fill-up.
Differential
It’s easy to forget to check the oil level in the differentials. After all, you have
to crawl under the vehicle to do it.
Take a close look at the sight glass. The
oil level should be at 3/4 full. If the level
gets to 1/2 or below, fill the differential to
3/4 with gear oil, NSN 9150-01-035-5393.
Don’t worry about overfilling. The bot-
tom of the fill plug is just below the top of
the sight glass, so you can’t overfill the
differential.

Engine Oil
Always make sure your
Stryker is on level ground before
checking the engine oil level after
operation. Also, the engine must
be shut down at least 20 minutes
before you pull the dipstick. The
oil level should be in the cross-
hatched area of the dipstick.
While you’re checking the oil
level, take a close look at the dip-
stick tube for cracks or leaks. Oil
overfill, discolored oil, or a
cracked dipstick tube deadlines
the vehicle.

H
ow important is it to keep up with the oil levels in your Stryker? Just ask that
Stryker driver on the side of the road. That’s him over there. The one with his thumb
