Final Installation Steps
After you are sure that the fifth wheel operates properly, wipe down the unit to remove any dirt or
oil. Touch up paint around welded area and newly installed metal. Cover the cylinder breathers so
that they do not get filled with paint.
Ensure protective face sheets from the warning decals located on the outside of the unit are
removed. Make sure that each decal is uncovered and that each decal is readable.
Apply the operating instruction decal inside of the cab in an area where the driver can clearly read
it. You may also have other decals or labels that are supplied with the unit. These should be
applied inside the cab near the controls.
Grease the top of the fifth wheel plate.
Warren suggests the use of a safety step deck plate (not supplied) to the area on top of the frame
where the driver will stand when hooking up trailer air lines and electrical lines.
When delivering the fifth wheel to the user, be sure to give them the operating instruction along
with this installation and service manual.
Check Out Installation
The 5
th
wheel installation should be thoroughly checked out before the unit is coupled with a
trailer. Then, it should be checked out while handling a loaded trailer.
Check components and Operation
PICK UP RAMPS:
•
Be sure the pick up ramps are properly installed to help slide the trailer up to the 5
th
wheel height. This is essential!
Framing and Reinforcing Members:
•
Are welds and fasteners tight?
Cylinder(s) and Front Elevators
•
Does the unit move up and down freely without rubbing or contacting other components?
Power Take Off:
•
Has transmission oil been replaced?
•
Does the PTO run smoothly and quietly?
•
Are there any leaks between the PTO and transmission or the PTO output shaft?
Hydraulic System:
•
Are there any leaks at pump output shaft, bushing reducers, hose unions or hoses?
•
Are hydraulic cylinder(s) leak-free?
•
Is tank full of oil?
•
Are all hoses properly routed and tied down to prevent pinches and wearing?
Check Out Performance
All 5th wheel assemblies are checked and thoroughly tested for proper locking before shipping.
However, it is imperative that before the unit is released for service it be thoroughly checked out
for coupling ability, and for the ability of the king pin jaws to properly lock. This is extremely
important, not only for safe operation, but for efficient performance as well.
