Maintenance
Replacement Procedures
Front Idler
Follow this procedure for replacing the front idler
(Figure 5-28):
1. Raise conveyor and insert safety prop.
(Page 5-6)
2. Locate track tensions manifold and back the relief
cartridge out of the aluminum block about three
turns until you hear the tension pressure release.
NOTE: Perform this additional step for poly or steel
tracks only: Rotate the track so the master
pin is at the rear bottom of the front idler and
back up the paver until the track clears the
front idler.
3. Jack up the paver at least two feet (61 cm) off
the ground for enough clearance under the
undercarraige to perform this procedure.
Crush hazard! Always use safety
blocks in addition to jack when working under the
paver to prevent serious injury or even death.
4. Remove the clip pin from the cylinder rod and idler
bracket. Idler will slide out.
5. Remove the idler bracket and bolt to the new idler.
6. Install idler, ensuring cylinder and clip pin are
aligned properly.
7. Lower sprocket back down toward the track
chain,ensuring the sprocket is about one (1) inch
(2.54 cm) from the chain.

Figure 5-27. Generator Flow Control Adjuster
1 - Gauge Port
2 - Fine Tune Speed Adjuster
Adjusting the flow-control adjuster on the front of the
manifold controls speed of the generator.
(Figure 5-27)
To perform this adjustment:
•
Locate the Flow Control Adjuster and turn to increase
or decrease the speed as needed.
•
Turning clockwise will decrease the generator speed.
Turning counterclockwise will increase the generator
speed.
If the generator will not operate at the correct speed,
test the hydraulic flow from the pump or check the
generator motor for excessive case drain flow. The
case drain should not leak more than one gallon per
minute. Replace the generator motor or paver pump if
either are operating incorrectly.
Generator Capacitor
The generator capacitor controls and regulates voltage
while the machine operates. If the capacitor fails, the
voltage will drop below normal or no output at all. It’s
located in the rear of the generator controls.
If experiencing a drop in voltage, replacing the capacitor
will help determine if the capacitor is at fault.
To perform this procedure:
1. Shut down the machine.
2. Detach the wires on top of the capacitor.
3. Remove the capacitor and replace with new one.
4. Reattach wires.
