A
little lube in the right place works wonders on your scoop loader. Avoid unnec-
essary repairs with these PM lube pointers before your loader heads out for the day’s
run.
Engine Access Panels
Pull latches on the engine’s access
panels get caked with mud. That rusts
the latches’ internal spring in place
and that makes them a bear to pull
open when you need to remove the
panels 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 vigor-
ously 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, causing the latch to stick in the
open position. Then you can’t shut
the door properly 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 spray
around the latch. Do this once a
month so the latch will open and
close smoothly.

Pivot Pin Pointer
Pivot pins on the clamshell bucket and
the bucket lift arms need lots of clean lube
to do their job.
Those grease fittings are usually coated
with dirt and sand. Make sure you wipe
gunk off the fittings before you start the
lube job.
And don’t forget to wipe off the dirty
end of the grease gun. 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
fittings until you see clean grease oozing
out. Six to eight pumps should do it.
If a fitting clogs and won’t take grease,
report it. Have your mechanic replace the
fitting with NSN 4730-00-050-4208.
Snub the Smear Job
Windshields on some scoop load-
ers are getting the royal smear job.
That’s because the spray nozzle
for the windshield washer fluid is
located smack dab in the middle of
a bunch of grease fittings just below
the loader’s windshield.
The nozzle looks just like the
grease fittings, so it’s not surprising
that it gets pumped full of grease
each time the fittings are lubed.
Grease either clogs the nozzle or ends up on the windshield when you push the
washer fluid 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 fitting.”.
