Best Practices for Recovery
Rigging
CAUTION
Recovery pull maximums assume the
tow
rigging evenly distributes the load
between both recovery hitches. See
examples in Recovery Rigging for de-
tails. Serious damage to the vehicle
may occur if rigging is not connected
properly.
CAUTION
When recovering ditched or bogged
vehicles,
stay well below Maximum
Capacities. Even at loads below maxi-
mum, the physical strain of recovering
a vehicle could damage axles, suspen-
sions, fifth wheels, etc.
Recovery Rigging Options
Use a double chain or cable setup that
distributes the load equally to both hitches
(see either example in Recovery Rigging
Options illustration):
•
Never loop a single chain or cable
through both hitches, also known
as reeving (not shown).
• Use a spreader or equalizer bar to
distribute the load on both hitches
(1), or
• If no spreader bar is available,
connect the main tow chain or
cable no closer than 6 ft. (1.8 m)
from the vehicle: (2) to (3).
• Secure the towed vehicle using two
additional chains or cables (see
Safety Chains) (not shown).
Returning to Service After
Recovering
Once the vehicle is recovered, the axles
need to have oil added to prevent gear
damage during operation.
1.
Into the pinion cage, add 1 pint (.47
liter) of lubricant or into the
interaxle differential, add 2 pints
(.94 liter) of approved lubricant.
2. After adding the specified type and
amount of lubricant, drive the
vehicle. It should be unloaded.
Drive 1 to 2 miles (1.5 to 3 km) at a
speed lower than 25 mph (40
km/h). This will thoroughly circulate
the lubricant through the assembly.
3. If the parking brakes were
manually released, they will need
to be modified back to their normal
operating condition.
4. If the differential lock was manually
locked, then the caging bolt needs
to be put back in its storage
location and the differential lock air
line needs to be re-installed in its
normal position.
Add lubricant back to the axles after
recovering the vehicle and before putting it
back into service.
