Adjusting the generator belt every 250 hours (quar-
terly) for optimum performance is a simple procedure.
You can access the generator from the center engine
access panel or by raising the main cover.
To adjust the belt tension on the generator:
1. Slightly loosen the bolts on the generator plate.
(Figure 5-36)
2. Slightly tighten the generator mount bolt until you
have approximately 1/2 to 3/4 inches deection with
minimal force.
3. Retighten the bolts on the generator plate.

Beacon and Work LightsBeacon and Work Lights
Inspect lights for proper operation daily. If a light or
group of lights does not function:
• Check the fuse box panel for a blown fuse.
• Examine all visible wiring connections, ensuring they
are not frayed or damaged, and securely fastened.
• Check lighting mounts for proper ground.
• Inspect wiring harness for damage. If broken wires are
found, solder together and cover with a shrink-wrap
type of plastic covering (preferred) or electrician’s
tape to prevent contamination of the solder joint by
moisture.
If you make any repairs to the wiring harness, always
replace or repair the protective loom covering the
wiring to prevent future damage to the wiring harness.
Examine the routing of the harness and ensure it is not
subjected to excessive movement, which often causes
broken wiring.
Generator Speed CheckGenerator Speed Check
The generator should never be
operated at a speed of 2100 RPMs or greater.
A voltmeter set to read frequency (Hz) can be used to
test generator speed. When the engine is running at
2100 RPMs, the generator should operate at 60 Hz.
Make certain that the paver engine is running at 2100
RPMs and the hydraulic temperature is at normal oper-
ating levels.
Generator Capacitor Generator Capacitor
ReplacementReplacement
The two generator capacitors control and regulate
voltage while the machine operates. (Figure 5-35) If
the capacitor fails, the voltage will drop below normal or
no output at all. It is located under the generator cover.
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.
