Reroute hose to
prevent rubbing
echanics, the way coolant hoses are routed can make the difference between
a Bradley that’s ready to go and one that leaks like a sieve.
On most Bradleys, the small surge tank coolant hose lays across the radiator
inlet hose. With the engine in place, the surge tank hose is pressed against the
inlet hose by a metal beam in the engine compartment.
That constant pressure is worsened by engine vibration. Eventually it cuts the
radiator inlet hose. Then you’ve got a leaky hose to replace.
You can prevent this damage by rerouting the surge tank hose. Use two 6-in
wire ties, NSN 5975-00-984-6582, to attach it to the second surge tank hose.
That keeps it above the radiator inlet hose and out of the danger zone.

rewmen, when erecting the boom on your M88A2 Hercules, pay special
attention to the hoist winch cables.
The cables often get hooked under
the cable lug (deadman). The pressure
frays the cables and can even snap the
bolt that holds the deadman in place.
With no way to anchor the winch
cables to the boom, you won’t be do-
ing any lifting.
So do yourself and your Hercules a
favor. Make sure the cables clear the
deadman as the boom is raised.

echanics, pulling and reinstalling the
M578 powerpack causes a lot of wear and
tear on the turbocharger air inlet hoses.
The cuts and tears that develop let in dirty,
unfiltered air—a real engine killer.
Look at those hoses every time you pull the
powerpack. If they’re badly scuffed or cut,
replace ’em with NSN 4720-01-058-5103.
Of course, the clamps that hold the hoses in
place are important, too. If they’re damaged
or no longer tighten enough to seal the hoses,
get new ones with NSN 4730-00-725-0537.
Good hose and clamp PM is a sure-fire way
to keep that vehicle breathing easy.
