2. Confirm lockdown pins are in the extended position. Both pins should be fully
extended through fifth wheel assembly frame rails and through lockdown plates
(see Figure 4).
3. Back up close to the trailer, centering the kingpin on the throat of the fifth wheel.
STOP.
4. Block the trailer’s wheels. Connect air lines and set the trailer brakes.
5. Check to see that the trailer is at the proper height for coupling. The front of the
bolster plate should contact the fifth wheel approximately 4 inches to the rear of
the fifth wheel’s articulation point. If not, raise or lower the trailer landing gear to
obtain this position (see Figure 2).
6. Back under the trailer, engaging the fifth wheel locks with the trailer kingpin. Pull
forward to test the completeness of the coupling as an INITIAL check. Set the
tractor brakes.
A direct visual inspection assures proper coupling. The trailer plate
must be on the top plate of the fifth wheel and the locks closed
on the kingpin as shown in Figure 3.
7. Engage manual secondary lock. To engage the secondary lock, remove the handle
loop end from the parking hole in the top plate and allow the handle to move in
which causes the secondary lock to pivot behind the locking yoke. (See figure 1).
8. Fully retract the trailer landing gear.
9. Remove blocks, release trailer brakes and “MOV-ON”.
Uncoupling Procedures
1. Position the trailer in the desired location, one that assures firm support for the
landing gear.
2. Set the trailer brakes. Tractor brakes should be released.
3. Extend trailer landing gear to ground to support trailer.
4. Block trailer wheels, disconnect and store air lines and light cord.
5. Check to see if the secondary lock is engaged. If it is engaged, release it by pulling
the secondary lock handle. To keep the lock open, place the handle loop end in the
parking hole of the top plate. This holds the lock away from the yoke (see Figure 1).
6. Push the fifth wheel lock control valve and hold in as you pull slowly out from the
trailer and “MOV-ON”.
Maintenance
1. Check top plate lockdown mechanism cables. With handle in “Highway Use”
position cable should be moderately tight and not sagging excessively. If cable is
loose, rotate turnbuckle to tighten cable (see Figure 5).
2. After tightening, cycle handle from “Yard Use” to “Highway Use” position several
times to confirm pins are extending and retracting as described above and to
confirm cables are not binding or being pinched.
