Engine Access Panels
Pull
latches
on
the
engine’s
access panels get caked with mud.
That rusts the latches’ internal
spring in place and makes the
latches a bear to pull open when
you need to get at the engine.
Free up the spring with a shot
of lubricating spray, NSN 9150-
00-458-0075.
Open
and
close
the latch vigorously a few times.
Then spray the spring at every
scheduled service.
Door Handle Latch
The
spring
latch
behind
the
door handle is constantly exposed
to
the
elements.
That
means
corrosion sets in and the latch
sticks in the open position. Then
you can’t shut the door or keep it
closed.
Get the “stuck” out with a shot
of lubricating spray. Open and
close the door a few times to work
the lubricant around the latch. Do
this once a month so the latch will
open and close smoothly.
A
shot of lubricating spray or a few pumps of grease in the right places will work
wonders on your scoop loader. Avoid unnecessary repairs by following these PM
lube pointers before heading out for the day’s run.
Pivot Pin Pointer
The
pivot
pins
on
the
clamshell
bucket and bucket lift arms need lots of
clean lube to do their job.
Those
grease
±ttings
are
usually
coated with dirt and sand. So make sure
you wipe any gunk off the ±ttings before
you start the lube job. And don’t forget
to wipe off the dirty end of the grease
gun between lube points. That way you
won’t pump any grit into a pivot pin.
Lube the pivot pins on the clamshell
bucket every week. If you don’t, the pins
will bind and break. Then your loader’s
down until the pins are replaced.
When you lube, pump grease into the
±ttings until you see clean grease oozing
out. Three to ±ve pumps should do it.
If
a
±tting
clogs
and
won’t
take
grease, report it. Your mechanic will
replace the ±tting with NSN 4730-00-
050-4208.
Snub the Smear Job
Windshields
on
some
scoop
loaders are getting a royal smear job.
That’s because the spray nozzle
for the windshield washer ²uid is
located smack dab in the middle of
a bunch of grease ±ttings just below
the loader’s windshield.
The
nozzle
looks
just
like
the
grease ±ttings, so it’s not surprising
that it gets pumped full of grease
each time the ±ttings are lubed.
That grease either clogs the nozzle or ends up on the windshield whenever you
push the washer ²uid button to clean the windshield.
One way to prevent this mess is to have your mechanic stencil a small note below
the nozzle that says, “Not a grease ±tting.”
MW24C Scoop

…PM Lube
Pointers!
this is a
spray nozzle,
not
a grease
fitting!
and keep your lube
instructions handy to
be sure you’re lubing
only
fittings…
…and that you
have lubed
all
of them
remember to
wipe off grease
fittings
before
you start
lubing!

That’s a nice
pointer you’ve
got there, but
your readers
will probably be
more
interested
in these…
