eed to add oil to the wheel hubs on your Stryker? Make sure you take it easy when
removing or tightening the hub’s fller/drain plugs.
The hex-shaped recessed area oF
the plug will strip and round oFF iF
you’re not careFul. That makes the
plug very hard to install or remove.
Make sure you insert your wrench
all
the way into the plug beFore
turning. IF you don’t, the wrench will
slip and the plug is damaged.
It’s also a good idea to keep a Few
extra plugs, NSN 5365-01-157-1347,
and gaskets, NSN 5330-12-156-4524,
on hand in case one is damaged. A
plug and gasket cost less than $2, so
having a replacement is more than
worth it iF a plug strips while you’re
in the feld.
Once the plug is removed, look
at the inside tip. The inside tip oF
the plug is magnetized, so you may
fnd tiny metal shavings stuck there.
Metal shavings could mean wear to
the planetary gears in the hub. Tell
your mechanic.

t’s only natural, mechanics. When doing repair work in the engine compartment oF
a Stryker, most oF your concentration is on what you’re doing with your hands.
But where you place your Feet needs attention, too.
A boot in the wrong place—say, on the thermal control maniFold—is a big
problem. Stepping on the maniFold can loosen or even crack the seals on the two
quick-disconnect couplings. Then you’ve got a hydraulic leak to fx and a big mess
to clean up.
IF you need a place to step on the engine, use the non-skid plate just to the side oF
the maniFold oF the CAT 3126 engine. Not only does that prevent damage, but you’re
less likely to slip and hurt yourselF.
