Dear Half-Mast,
I need help! We can’t find an NSN for the stay line holddown clamps or
the tow cable mounting clamps for our M88A1 recovery vehicles.
The clamps for both locations look like they’re the same, but we can’t find
them in the parts TM.
Mr. J.C.P.
H
ow much lube an AVLB roadwheel hub gets depends a lot on how you install its
cover plate, mechanics.
There are two types of roadwheel hub cover plates still in use. The Frst cover plate,
NSN 5340-00-736-4254, has a plunger-type relief valve in its center. The second
cover plate has the relief valve located on the side. Though it’s no longer in the
supply system, the second cover plate is still in use on some AVLBs.
To ensure that all the hub gets grease during lubing, make
sure the cover plate is installed with its relief valve positioned
opposite
the grease Ftting on the hub.
Dear Mr. J.C.P.,
The clamp you need comes
with
NSN
5340-01-384-
9998 (PN 6208845, CAGE
19207). The original NSN
was cancelled by DLA and
had to be reprovisioned. It’ll
be included in the next update
to TM 9-2350-256-24P-1.
If the Fttings are close together, only part of the hub gets
new grease before new lube comes out of the relief valve.
The dirty grease doesn’t get pushed out and that can lead to
burned-out bearings.

there’s no
problem with the
first cover plate.
it’s the
second
one you have to
be careful with.
Replacement clamps come with NSN 5340-01-384-9998
hey,
my roadwheel
hub lube fittings are
too close together!
trust me, it’s
not
a match
made in heaven!
Make sure grease Ftting and relief valve are 180° apart
If Fttings are together, hub isn’t lubed properly
the nsn for the
clamps you need
must be lost!
I can’t find
them!!
hey,
you
can count on
half-mast’s
lost and
found service
for help!
