HYDRAULIC AND ELECTRICAL CONNECTIONS
HYDRAULIC PTO CONNECTION
Figure 7- Front PTO & Electric Connections
No PTO hoses or pump are supplied with customer installed truck beds because of the
variation in truck bed mounting. These parts are available for purchase and installation
through the Trinity Service department.
It is strongly advised that if your PTO system
does not have a pressure relief valve and filter that these items be installed before
using your truck bed to ensure system protection.
PTO PUMP PRESSURE LINE
If your truck bed has PTO system, the pressure line from the PTO pump connects
to the 3/4" hose (coming from the flow control valve located at the rear of the
truck bed) terminating at the front of the truck bed. A capped 1” NPT Male hose
fitting is supplied for this connection.
PTO PUMP SUCTION LINE
If your truck bed has PTO system, the suction line from the PTO pump connects
to the 1" hose (coming from the oil tank) terminating at the front of the truck bed.
A capped 1” NPT Male hose fitting is supplied for this connection.
