Prior to towing a truck, many factors must be carefully
considered. Serious personal injury and/or significant
property damage may result if important safety prac-

Both right and left planetary sun gears/drive axles
should be removed before any towing. Refer to
Section "G" in the Service Manual for these instruc-
tions.
Extensive secondary damage can occur to final
drive components and/or
transmission, if truck is towed without first remov-
ing sun gears/drive axles.

following MINIMUM precautions have been taken.
1. Shut down engine.

special instructions.
3. If truck is equipped, install hydraulic connections
for steering and dumping between towing and
towed vehicles.
4. Be certain tow bar capacity is approximately equal
to 1.5 times the gross vehicle weight of vehicle
being towed.
5. Determine that towing vehicle has adequate ca-
pacity to both move and stop the towed truck
under all conditions.
6. Protect both operators in the event of tow bar
failure.
7. Block disabled truck to prevent movement while
attaching tow bar.
8. Release disabled truck brakes and remove block-
ing.
