Access Cover
The access cover for the SEE’s rear hydraulic oil tank holds water. Over time,
water rusts and deteriorates the cover.
In some cases, the cover has been known to spring a leak like a geyser when the
engine is working hard during backhoe operations. Those operations come to a halt
when the hydraulic system
loses fluid.
So eyeball the cover. If it’s in
bad shape with lots of rust,
report it.
Your mechanic can replace a
cover with NSN 5340-01-235-
2151 or sand away the rust and
use CARC paint, NSN 8010-
01-229-7546, for touch-up.

Windshield Washer Hose
The rubber hose that attaches to the
washer fluid reservoir can crack or split
from temperature changes (engine heat
and cold weather) and vibration.
Then the windshield washer pump
sucks air instead of fluid and you can’t
clean the windshield.
Mechanics can fix the problem like so:
Eyeball the hose where it attaches to
the nipple on the windshield washer jar.
That’s where the hose usually splits.
Snip off a half inch or so of hose and
push it back in place.
If you still don’t get washer fluid,
have your mechanic check out the pump
or replace the rubber hose with NSN
Power Steering Pump
Hard or erratic steering means either
the power steering fluid is low or the
steering pump’s filter is clogged.
So, eyeball the fluid level on the dip-
stick. Make sure the fluid level is
between the ADD and FULL marks.
Normal operation at the construction
site causes the pump’s filter element to
clog up. A clogged filter starves the
pump for oil. No oil means tough steer-
ing. So make sure your mechanic
replaces the pump’s filter element dur-
ing scheduled service.
