6.
Remove the arm dump valve and orifice block and reinstall the pressure line.
The pressure line was connected to the arm dump valve, directly to the arm pump. You will need
shorter bolts to tighten it down.

7.
Open the ball valve (or shut-off valve) that was closed in step 3.
8.
Start the truck.
Note that the second the truck is running there will be hydraulic fluid going to the arm valve
assembly. The Emergency Stop will not stop the hydraulics from working, only turning the truck
off will. Ensure everyone, and everything, is out of the way of the arm in case it moves on its own
should there be an electrical short or a catastrophic failure internal to the valve assembly.
Now that the arm dump valve is bypassed, we will be able to identify if the arm pump or arm
dump valve is faulty. Simply go to the arm valve assembly and operate the arm manually.
- If the cycle times and pressures are correct, then the arm dump valve is faulty.
- If the cycle times and pressures are still not correct, then the arm pump is faulty.

Assembly in the opposite of disassembly.
Tailgate-Locking Mechanism
N
OTE
:
See the main hydraulic schematic specific to your truck. A number of hydraulic schematics are
found in this manual starting on page 151.
The tailgate-locking mechanism is equipped with hydraulic safety devices that prevent accidental
unlocking of the tailgate during operation. One of these devices is the velocity fuse (see Figure 8
10)
with the
power bleed feature, another is the holding valve (see Figure 8
9).
