echanics, there’s a right way
and a wrong way to install the
MLRS’ fan drive propeller shaft,
NSN 2520-01-108-9273. The choice
you make will determine how well
the prop shaft does its job—and for
how long.
The prop shaft connects the final
drive to the right angle drive. If it’s
put in backward, water works its way
into the yoke assembly. That causes
slack in the prop shaft, dried-out
bearings and eventually a broken
prop shaft.
You can prevent damage by
installing the prop shaft the right way.
The thicker portion of the shaft goes
down and attaches to the PTO yoke
on the final drive. Then water cannot
get into the yoke assembly
1.
Make sure all hull drain
plugs and both final drive
drain plugs are in place and
secure.
2.
Choose a spot to enter
and exit the water. Look for
firm ground without rocks,
stumps or other obstacles.
Try to avoid steep slopes.
3.
Flip the forward and rear
bilge pump switches to ON.

rivers, swimming your Bradley is no longer allowed, but you can still ford
water up to 31∕2 feet deep.
If you don’t ford properly, though, you may not make it out the other side of the
creek. So, follow these steps:
4.
Enter the water at no
more than a fast walking
pace (about 2 mph or less).
If you try to go faster, water
will splash up into the air
intake system and damage
the engine.
5.
Once into the water,
center the steering yoke and
try to keep the tracks on
solid ground. Feel your way
across, trying to avoid under-
water obstacles.
Be pre-
pared for sudden stops.
7.
After the bilges are empty, flip the bilge pump
switches to OFF.
6.
Exit the water with the steering yoke centered.
Don’t leave the water at an angle to the bank.
