General Information
The descriptions and specications provided in this
section are applicable to the LeeBoy Model 8616
Conveyor Paver.
This section contains a description of how the major
components operate. It also includes specications for
the major system components. Included in this section
are paver weights, dimensions, performance, and major
system specications for the paver.
Major Components
The LeeBoy Model 8616 Conveyor Paver uses a
Kubota, 99 HP (74 kW) diesel engine to drive the
hydraulic function pump and steering pump. The
engine is mounted near the center of the paver and is
accessible through several access doors in the engine
cover.
A fuel lift pump mounted on the engine draws diesel fuel
from the fuel tank. The fuel tank is mounted at the right
side of the engine compartment.
An air cleaner is mounted at the back of the hood. The
air cleaner removes ne particles such as dust, sand,
chaff and lint from the air.
As air is taken into the air cleaner assembly, a cyclone
type action deposits some of the ne particles in the
evacuator mounted on the bottom of the air cleaner
housing. The evacuator is held closed during engine
operation by suction. When the engine is shut off the
weight of the debris helps to open the rubber aps
allowing the debris to fall out. The rubber aps can also
be squeezed to open for cleaning.
A fuel lter removes contaminants from the diesel fuel
before the fuel ows to the injection pump for injection
into the engine combustion chamber.
A radiator mounted in front of the engine cools the
engine. As coolant ows through the radiator, airow
from the engine-driven fan removes heat from the
coolant.
Refer to the engine owner’s Operation and Maintenance
Manual for a complete description of the engine.
The hydraulic system includes four hydraulic pumps
driven by the engine: 1) Left Drive Pump, 2) Right Drive
Pump, 3) Load Sense Pump and 4) Charge Pump.
The paver drive system contains two torque hubs. The
torque hubs provide power to propel the tracks.
The hopper wings are hydraulically controlled to raise
and lower. The hopper when fully open can hold a
payload up to 9 tons.
Material in the hopper is moved toward the back of
the paver to the screed by conveyors. The conveyor is
activated at the operator platform.
The RIGHT and LEFT augers rotate clockwise (CW)
to assist in moving material from the conveyors to
the screed. The auger can be manually controlled at
the operator platform on the paver or by the screed
operator on the screed.
The auger can also be controlled automatically when
the sonic auger system is installed and active. The sonic
auger sensor mounted on the screed endgates detect
the amount of material present and control the auger to
keep the material ow constant.
The operator platform allows easy and convenient
control of most all functions of the paver and screed.
The paver can be operated from either the left-hand
or right-hand side depending on which control panel
side is active and best suited to the working conditions.
Controls can also be lowered to run as a lowdeck or by
standing on screed walkboard.
