Rocking out.
These heavy trucks sometimes can be self extracted from soft area by rocking them out. Do not allow wheels to
spin! Shift the main power shift transmission between 1-2 gear and reverse gear slowly, Just matching the fore and
after movement of the truck. Starting with the engine idling, try it by very gradually increase accelerator pressure
with each rocking cycle. Do not attempt to return to idle each time, but keep the accelerator setting steady through
each cycle, as you shift from forward to reverse. The torque converter and PS transmission clutch packs smooth
the torque reversals so the wheels should not spin. As soon as the truck gains enough momentum plus traction
combination, if conditions are right, you'll be able to get out of the soft spot. Remember that, in using the torque
convertor and the clutch packs during rocking, you are creating a lot of heat. Keep an eye on those engine and
transmission temperature gages and if, after a number of tries, you see these temperatures going up (especially if
the PS transmission temperature exceeds 250 F), then stop rocking immediately and shift the main PS into neutral,
speed up the engine RPM to read about 1500 to 1900, and let things cool back down. If conditions for self
extraction aren't right and the soft spot is way too deep, then further steps are necessary.

Brute Force:
Again, what do you do if you're really, truly stuck, immobilized, can't move and you have proved it? There are many
steps to be taken under these conditions. Put one foot in front of the other and go for outside help! Make sure the
help you get has the capacity and the footing (drawbar pull on suitable soil conditions) to pull from 25 to 100% of the
weight of your stuck truck. Only in exceptionally easy cases will the Army field expedient methods be able to
extract heavy trucks of the CCE-IHC Dump Truck class. You can forget any ideas of connecting a team of trucks in
tandem or tridem or calling out companies of men to push and play tug-of-war. You'll need some real heavy artillery
to do this man size job. The CCE dump truck, like most commercial on-off-road heavy
