M917A1 Dump Truck . . .
Clean Out Wheel Rims
O
perators, wheel rim openings on the
M917A1 dump truck are havens for
packed mud, sand, small rocks and dirt.
All that crud breaks down the rubber
on the CTIS hoses that pass through the
wheel openings.
When the hoses start to rot, they leak.
Then the CTIS can’t inflate or deflate
the tires during operation. You could end
up stuck in the mud at a worksite.
So when you’re cleaning the vehicle, make sure you clean out the wheel
openings with high-pressure water. It’ll save on maintenance repairs down
the road.
attery and battery box maintenance on 130G grad-
ers is a team effort.
Operators, your job is to keep an eye on the tops of
the batteries. Sand and dirt that collect there turn into
mud in wet weather. Mud holds moisture that can close
the circuit between the positive and negative terminals
and discharge the batteries.
So take the time during battery checks to clean off
any dirt or mud.
Mechanics, any time you take the batteries out, eye-
ball the condition of the battery box. Water in the bot-
tom of the box causes rust.
Use a wire brush to scrape off rust and old paint.
After cleaning, protect bare metal inside the box with
bituminous coating compound, NSN 8030-00-290-5141.
