Dear Half-Mast,
TM 9-1450-646-10 tells us to raise and lower the cab on our MLRS
with the 1/2-in drive ratchet and 5-in extension from the BII. Problem is,
the cab jerks and bounces a lot. With the close clearances, it’s pretty easy
to bust your knuckles.
Isn’t there a better way to do the job while saving our skin? How about
using an electric impact wrench to get the cab up and down?

Dear Sergeant I.A.I.,
Do
not
use
any
kind of power tool to
raise or lower the cab of your MLRS.
That can damage the lift mechanism
and you can be injured if the cab falls.
There is another way to make cab
lifting and lowering easier and all
you’ll need is a $14 tool.
Socket wrench handle, NSN 5120-
00-249-1071,
has
a
brace-type
speeder handle with a single revolving
handgrip. The tool makes lifting and
lowering the cab quick and easy while
saving a lot of wear and tear on your
knuckles.
Table B-1 of CTA 50-970
is your authority for
ordering the handle.
