MLRS Launcher.
..
ood lubing is what some parts of the MLRS launcher need on a weekly basis to
prevent expensive damage.
Boom rollers
—If the rollers aren’t cleaned
and lubed weekly in the field, they develop flat
spots that can damage the W75 and W76 cables
and crack the screws that hold the end beam
mounting brackets.
So, clean the rollers weekly with lubricant
cleaner, NSN 9150-01-054-6453. Then clean off
the cleaner with dry cleaning solvent. After the
solvent dries, apply dry lubricant, NSN 9150-
01-443-9003. The complete procedure is spelled
out in Para 3-9(b) in TM 9-1425-648-13&P.
LLM hoist pulley crank
—If the
crank is frozen with rust, the MLRS
can’t be adjusted for different rockets.
Use dry lubricant on it, too, and exer-
cise the crank handle to work the lube
in the handle bearing and hinge pin. If
the handle doesn’t want to turn, don’t
force it. The aluminum handle can
snap right off. Tell your repairman.
Azimuth geared bearing
—If
the bearing’s old grease isn’t
cleaned out every 12 months by
your repairman before new grease
is applied, it can harden and make it
hard for the launcher to move. The
cleaning procedure is item 2b in the
PMCS Quarterly Service in TM 9-
1425-648-13&P.
If you get shaking as you move
the launcher, check the four bolts
that hold the azimuth speed reducer
in place. Loose, broken or missing
bolts are one of several possible
causes of shaky azimuth movement.
Report bolt problems immediately.
