fittings. If you see fluid coming out of
any fitting, tighten the connections.
If the leak continues, replace the
leaking parts. They’re listed in callout
E in Fig 28 of TM 9-1450-646-24P.
Area 2
Look for a leaking connection at the
solenoid valve, NSN 4810-01-108-
5223.
A leak can limit the pressure at the
valve. Without enough pressure to
force fluid through the solenoid, the
system won’t lock the roadwheel sup-
port arms. Make sure the connections
are all tight.
Check for leaks at suspension

echanics, if you can’t get the sus-
pension lockout (SLO) system work-
ing on an MLRS, your first stop should
be the troubleshooting procedures in
TM 9-1450-646-20-1. The task list on
Page 3-9 tells you where to find them.
But if troubleshooting leads to a dead
end, don’t despair. There are two other
areas that could be the source of the
problem:
Area 1
The hydraulic lines that attach to the
SLO assemblies on the numbers 1, 5
and 6 roadwheel support arms could
be leaking.
Get someone to pump the SLO
