Leeboy Model 8515D Conveyor Paver 3-3
Component Location
Hydraulic System
The hydraulic system includes hydraulic pumps, motor
and cylinders that work together for optimum machine
component control. Valves regulate the directional,
pressure and uid ow throughout the hydraulic system.
The LeeBoy 8515D Conveyor Paver now features
a hydraulic test ports for ease and convenience in
checking pressure for its ve main functions.
Torque Hubs
The paver drive system contains two torque hubs that
provide power to propel the tracks. Two-speed motors
power tough planetary drives for smooth operation.
Hopper and Conveyors
The hopper wings are hydraulically controlled to raise
and lower the hopper. When fully open, the hopper can
hold a payload up to 7.5 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. Its wide, automatic
conveyors with a wide hopper design delivers asphalt
more evenly and efciently to produce a smooth asphalt
mat.
The hopper’s conveyor bed can be lifted hydraulically,
allowing easy access to the paver undercarriage and
tracks for service and cleaning.
Components Overview
This section describes the major components for the
LeeBoy 8515D Conveyor Paver. Become familiar with
these components before operating the machine.
Engine
The LeeBoy Model 8515D Conveyor Paver is equipped
with a Kubota, 74 HP (55.2 kW) diesel engine mounted
on standard heavy-duty vibration isolators. It is
accessible through several access doors on the engine
cover, especially the front service door mounted with
all fuel lter components for easier access. This paver
features improved visibility with a low-prole engine
cover along with easy access to engine relays and the
fuse panel.
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, the cyclone action deposits some
of the ne particles in the evacuator that is 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 opens
rubber aps, allowing the debris to fall out. These aps
can also be squeezed open for cleaning.
The fuel lter removes contaminants from diesel fuel
before it ows into the injection pump where it is injected
into the engine combustion chamber.
The radiator mounted in front of the engine cools the
engine. As coolant ows through the radiator, airow
from the engine-driven fan removes heat.

your paver for additional engine information.
