he cooling fans on your howitzer or
ammo carrier do a great job of keeping
the engine cool. But they can also do
a number on your fingers if you aren’t
careful.
Always use fan blade screens anytime
you’re doing maintenance on a running
engine.
The screens, NSN 2510-01-247-2976,
keep fingers and anything else from being
pulled into the blades as you check for
leaky hoses, pipes and fittings.
Each screen has hooks and a thumbscrew
and locknut to secure it to the fan shroud.
The screens should be used only during
scheduled maintenance, though. Remove
them before regular vehicle operation or
the engine will overheat.
As a reminder to use the screens, put
a warning decal, NSN 7690-01-244-9849,
on both fan tower shrouds. Use some
general purpose cleaner, NSN 7930-00-
515-2477, to clean the shrouds before
applying the decals.

ew things are more frustrating than trying to reconnect broken track or install new
track on your Bradley and not being able to line up the bushing holes just right.
If you don’t line up the bushing holes just so, good luck trying to slide in the
connecting pin. Even using the track connector seldom makes the task any easier.
But don’t give in to temptation and break out the sledgehammer to bang in the
pin. That may help work out your frustrations, but it causes damage to the pin and
bushings. That’ll eventually result in track failure.
A much better tool is a tanker’s bar. Just wedge the end of the bar between the two
shoes and pull up and down to manipulate the bushings until they line up. Then the
pin slides in easily.
Be sure to follow the track alignment procedures outlined in the
-10 TM.
