rewmen, checking the FRH level in the replenisher of your M1129A1 Stryker’s
mortar is a before-operations PMCS check. And it’s not something you want
to forget!
If the hydraulic fluid level is low, the gun tube can recoil out of battery when it’s
fired. Besides damaging your mortar, anyone that’s in the way could be seriously injured
or killed!
Checking the fluid level is quick and easy. Here’s how:
With the mortar in the stowed
position, slide the dipstick all the
way into the replenisher port. If
the white band on the dipstick
goes inside the port while the red
band stays outside, the oil level is
good.
If the white band is still visible, the replenisher is
too full. Drain the oil to the proper level. But if the
dipstick slides in past the red band, you’ll need to
add oil to the replenisher.
When dealing with FRH, you’ll need to take
some precautions, too. Make sure you’re wearing
long sleeves, gloves, goggles and a faceshield
when adding or draining the oil. FRH contains a
chemical that can cause paralysis if it’s swallowed.
FRH can also be absorbed through the skin, so
wash thoroughly with soap and water if you get
any on you.
The 1W102-7 P8 connector for the Blue Force Tracker (BFT) system is mounted
to the turret roof next to the gunner’s dome light. That puts it right smack in the way
of the recoil path of the main gun when it’s ±red at maximum depression.
The 1W102-7 P8 connector bracket is being redesigned to eliminate this
interference. But until that happens, you’ll need to move the connector out of harm’s
way. Here’s how:
1.
Disconnect the 1W102-7 P8 connector from the 1W352-7 J1 harness connector.
2.
Remove the harness connector
from its current position on the
bracket tab.
3.
Connect the 1W102-7 P8 and
1W352-7 J1 connectors back
together.
4.
Move the reconnected cable
assemblies
behind
the
mounting bracket’s tab.
5.
Secure the cable assemblies to
the mounting bracket using
two cable ties.
