I
f you have an RG-33L, RG-33 SOCOM, RG-33 HAGA, RG-33L Plus or HAGA
Plus MRAP here’s a shock about the bolts that attach shock mounts to leaf springs!
You need to replace all the lower forward shock absorber mount bracket bolts and
nuts that have not been marked with a torque marking. If you don’t have a torque
mark or your torque-marked hardware has become loose, use new nuts and bolts to
remount the shock mounts. These nuts and bolts are intended for one time use only.
Torque the new mount bolts to 420 ft-lbs. For RG-33 SOCOM, RG-33L or HAGA
variants, use NSN 5306-00-177-5672 to get new bolts. NSN 5306-00-576-2624 gets
new bolts for the RG 33L Plus and HAGA Plus variants. The replacement nut for all
variants comes with NSN 5310-01-484-7860.
After installing and torquing new
bolts and nuts, paint a torque mark
strip across each set. This will make
it easier to see if nuts and bolts are
working loose. It is also a visual cue
for seeing which of your vehicles
have had their nuts and bolts replaced
and torqued properly. If nuts and
bolts work loose again, replace them
with new nuts and bolts and make
another torque mark.
Dear Half-Mast,
I am deployed in Iraq and need to
know if service kits are available for
MRAP vehicles.
