What are the Best Practices for
Recovery Rigging?
Use these guidelines when recovering a
vehicle with rigging and hitches.
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.
Use a double chain or cable setup that
distributes the load equally to both hitches.
See 1 or 2 in Recovery Rigging illustration.
Never loop a single chain or cable through
both hitches (3).
Use a spreader or equalizer bar to
distribute the load on both hitches (1).
If no spreader bar is available, connect the
main tow chain or cable no closer than 6 ft.
from the vehicle (2).
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
